1.1 Research
1.1.1 Water-related disaster data archiving, sharing, and statistics
ICHARM developed a real-time flood forecasting system for the Pampanga River basin on
the Data Integration and Analysis System (DIAS) in collaboration with the Earth Observation
Data Integration and Fusion Research Initiative (EDITORIA), managed by the University ofTokyo, and started to provide flood forecasting information to related organizations in thePhilippines. ICHARM also developed the prototype system to upload the socio-economic,
damage, and hazard datasets of Davao City onto DIAS in collaboration with EDITORIA.
This system has a function to archive data with related meta-information such as theirelement, domain, period, spatial resolution, unit, and data-producing organization.
1.1.2 Water risk assessment
ICHARM developed the Water and Energy Budget-based Rainfall-Runoff-Inundation(WEB-RRI) model to analyze water-related hazard phenomena with high accuracy byintegrating the Hydro-SiB2 model capable of calculating the dynamics of the water andenergy balance with the Rainfall-Runoff-Inundation (RRI) model capable of 2D
runoff/inundation calculation. By using the new model in combination with atmosphericmodels, it has become possible to evaluate not only flood hazard impacts but also droughthazard impacts due to future climate changes. We developed another model that calculates
driftwood behavior as the density of sediment using a water/sediment momentum equation.
This model is suitable to reproduce typical flood and sediment hazard phenomena inmountain rivers. We have also been making efforts to disseminate these models by improving
their user interfaces and offering training activities for users.
In addition, we built a model for predicting the dam reservoir inflow by utilizing a runoff
model called the Water and Energy Budget-based Distributed Hydrological Model-snow(WEB-DHM-S), which estimates snowfall, snow cover and snowmelt quantitatively in
combination with rainfall forecasting information from ensemble weather forecasting. We are
studying the optimization of the current operation methodology for hydroelectric dams to
reduce ineffective dam discharges, improve power generating efficiency during a flood, andsecure the storage capacity of a dam reservoir after a flood.
1.1.3 Monitoring and forecasting water-related disaster risk changes
ICHARM proposed and applied a series of forecasting methods that can take theuncertainty of forecasting into account to three cities of Vietnam (Hue, Ha Giang, and Vinh
Yen) in an ADB project on climate-change impact evaluation. In this study, four GCMs were1

selected for their high expressiveness for meteorological factors; the uncertainty originatingin GCMs concerning future prediction were evaluated by applying statistical downscaling(DS); future climate scenarios were created using dynamic DS; and flood risk evaluation was
conducted using the RRI model.
1.1.4 Support through proposal, evaluation and application of policies for water disaster risk
reduction
In the World Bank Brazil project, ICHARM developed a real-time agriculture droughtmonitoring and seasonal prediction system for Ceará State in the Brazilian Northeast. By
using a Leaf Area Index (LAI), which is output from this system, a method was also devised
to estimate crop yield and the required volume of irrigation water. Furthermore, ICHARM
developed a high spatial-resolution system (1km grid) to estimate LAI growth for the
Banabuiú River basin, the most important basin in Ceará State. In addition, considering that
researchers familiar with local conditions should improve the system after learning its basic
theory, two researchers of the Northeast States Meteorology and Water Resources Foundation(FUNCEME), which is responsible for the meteorological drought monitoring and prediction,
were invited and received training at ICHARM.
Japan has many small and medium river basins. Since the water level during a flood rises
sharply in those rivers, riverside areas are exposed to a high flood risk with many residents at
a high risk of failing to evacuate safely. To address this problem, ICHARM developed an
inexpensive, simple technology for water-level prediction in the Public/Private R&D
Investment Strategic Expansion Program (PRISM), established by the Cabinet Office in
FY2018, in cooperation with local offices of MLIT. The system is designed to use real-timewater-level data collected from water gauges which have recently been installed in many
rivers specifically for emergency use during a flood.
In West Africa, flood disasters often occur in the Niger and Volta River basins, causing
deaths and hindering the development of the countries in the region. Hence, UNESCO
decided to develop flood monitoring and prediction systems over those basins and theirsurrounding areas in an effort to reduce human damage using flood information provided by
the systems. After concluding a partnership agreement with UNESCO in the framework of
the Water Disaster Platform to Enhance Climate Resilience in Africa, ICHARM developed aflood early warning system for the Niger and Volta River basins to help reduce water disasterrisks. Simultaneously, ICHARM invited engineers of AGRHYMET and VBA to Japan andprovided training about the flood early warning system and flood risk management.
As the representative organization for disaster risk analysis and evaluation in the ongoing
SATREPS project in Thailand, “Enhance regional resilience through visualization of disasterrisks with industry, government and academia collaboration,” ICHARM has been developing2

a flood inundation prediction model for the entire Chao Phraya River basin and the industrial
centers in order to prepare detailed information on water disaster risks.
1.1.5 Technological support for strengthening the capabilities of local governments inwater-related disaster management
ICHARM has been conducting research to assist local governments in strengthening theirwater-related disaster management capabilities. Our current research focuses on creating new
flood risk indicators using inundation simulation results by the RRI model and finding ways
to improve flood risk information sharing to assist local governments in mountainous areas
facing the lack of disaster information for the safe evacuation of residents. We also developed
a new portal site for disaster information sharing that allows one-stop viewing ofwater-related disaster information, and opened it for the public as test operation not only for
emergency use but also for improving the abilities of local governments and residents in
disaster prevention and mitigation in normal times.
In addition, we conducted questionnaire surveys from a perspective of behavioral
economics for residents living in areas affected by disasters in recent years. Based on thefindings that a flood experience leads residents to take appropriate actions such as early
evacuation, we developed simple simulation software using virtual reality (VR) technology
for people to experience simulated inundation in a private house.
We have also been studying new indicators to evaluate the aspects of disaster cases thathave not been evaluated adequately by existing methods. For example, we have conducted
on-site interviews and questionnaire surveys to identify indicators that can be used to evaluate
the resilience of residents and businesses in particular and the resilience of communities
affected by water-related disasters in general.
Furthermore, to assist local governments in improving its capacity to use a disaster
response timeline effectively, we studied disaster reports reviewing disaster response efforts
in past water-related disasters and analyzed issues to be overcome for strengthening thecapacity of administrative staff to take timely actions in time of a disaster.
1.2 Education and training
ICHARM has provided educational and training programs that are designed to strengthen thecapabilities of both individuals and organizations in disaster management.
The main programs include: 1. One-year master's degree program, "Water-related Risk
Management Course of Disaster Management Policy Program," conducted in collaboration withGRIPS and JICA; 2. Three-year doctoral degree program, “Disaster Management Program”
jointly conducted with GRIPS; 3. Short-term training programs held in Japan and overseas; 4.
Follow-up Seminar held annually overseas for graduates and trainees; and 5. Short- and3

long-term internship programs.
From 2018 to 2019, while continuing to provide these training programs, ICHARM steppedup the efforts to recruit quality candidates who are expected to be responsible for policy
development and implementation in the future in respective countries.
In 2018, JICA started a new scholarship program, “Disaster Risk Reduction Leaders Capacity
Development for the Sendai Framework Implementation,” for international doctoral students.
Since FY2018, two students have been enrolled, using the JICA scholarship. The program willcontinue to accept new students.
1.3 Information networking
ICHARM continues promoting information networking on a global scale. As a UNESCO
category 2 center, it keeps close ties with each UNESCO-IHP and its National Committee, other
UNESCO category 2 centers, and UNESCO Chairs. It also maintains cooperative relations withUN organizations such as WMO and UNDRR, and other international and regionalorganizations such as HELP and the Typhoon Committee (TC).
As the secretariat of IFI, ICHARM is promoting the global effort to establish Platforms on
Water Resilience and Disasters based on the Jakarta Statement, which was adopted by themember organizations as the basic action plan of IFI after the elaborations at the October 2016
workshop in Jakarta, Indonesia, and the January 2017 workshop in Tokyo, Japan. ICHARM has
been supporting the establishment of Platforms on Water Resilience and Disasters in thePhilippines, Myanmar, Pakistan and Sri Lanka. ICHARM has also started providing support forIndonesia.
At the Global Earth Observation System of Systems (GEOSS) Asia-Pacific Symposium andother similar conferences, ICHARM has held the Asian Water Cycle Initiative (AWCI) sessions
and invited representatives from the Platform implementing organizations of those countries
every year since 2017. In the past meetings, they reported the progress of their Platform projects
and discussed how to establish a regional cooperative framework among the participating
countries.
During the 2018-2019 period, important international conferences were convened around theworld, such as the 8th World Water Forum, the intergovernmental council meeting of
UNESCO-IHP, and the 4th UN Special Thematic Session on Water and Disasters. ICHARM
participated in those conferences and hosted sessions and side events, which strengthened therelationships with other participants and organizations and expanded the professional andorganizational network. Currently, a chief researcher of ICHARM assumes the chair of theWorking Group of Hydrology (WGH) in TC, which is an intergovernmental community jointly
organized by UNESCAP and WMO. ICHARM is playing the leading role in the implementationof the Annual Operating Plans (AOPs) in collaboration with the TC members.

２．Special topics
2.1 Development of a real-time agriculture drought monitoring and seasonal prediction system
In the World Bank Brazil project (Technical Assistance in Implementing a Pilot of Agriculture
Drought Monitoring and Prediction), DIAS collects and integrates three types of data in realtime: the NASA Global Land Data Assimilation System (GLDAS) meteorological global
forcing data, the GCOM-W/AMSR2 microwave brightness temperature global data, and theGeophysical Fluid Dynamics Laboratory Climate Model version 2.5 (GFDL) seasonal
predictive global precipitation data. By inputting these data into a land surface model, theCoupled Land and Vegetation Data Assimilation System (CLVDAS) can calculate the land
water cycle and the dynamic vegetation growth. Then, applying CLVDAS to the Brazilian
Northeast, ICHARM developed a DIAS
25km-gridded real-time agriculture droughtmonitoring and seasonal prediction system for
Ceará State in the Brazilian Northeast. The

Africa. The meetings were excellent opportunities for ICHARM to share its activities andachievements with the World Bank.
2.2 Study on Flood Awareness by Flood Simulated Experience using Virtual Reality
In recent years, floods have recurred frequently, causing significant damage. In particular,
many human casualties have resulted due to delays in evacuation. One of the causes that people
fail to evacuate timely is their low awareness towards floods; people tend to think that a disasterwill not occur to themselves.
To solve this problem, we developed a “Flood Simulation Experience Application,” whichenables the user to have a realistic flood experience by using VR technology, whose progresshas been remarkable in recent years. This application is expected to help people increaseawareness towards floods and thus to promote effective and efficient disaster prevention andmitigation activities by residents and other stakeholders involved in disaster prevention,
To verify whether the application raise flood awareness of the residents who have never seenor experienced a flood disaster before and motivate them to take action in time of flooding, we
conducted a questionnaire survey for 111 general visitors who tried out the application at anopen house event jointly held by NILIM and PWRI on April 19, 2019.
The survey found that the virtual flood experience gave a strong sense of fear to some people
who had never experienced a flood before. In addition, for more than half of the participants,
even though it was a virtual flood, the experience increased the level of concern about flood
disasters. Those who felt fear more intensely during a simulation were more motivated to lookat hazard maps.
Overall, the results confirmed that the application helped increase public awareness towards
floods and suggested that VR-driven flood experience can contribute to raising public awarenessof disaster prevention and increase their motivation to take action for safer evacuation.
We are planning to modify the VR
application to realize area-specific flood
simulation for different communities.
In addition, we conducted a poster
presentation at the World BOSAI Forumin Sendai, Japan, in November 2019 andprovided an opportunity for visitors to

Flood simulation experience by VR

have a VR flood experience.

62.3 Research Group on River Basin Design with Sediment Transport Processes
Flood hazards take place often in mountainous areas, and they are characterized by floodingwith a huge amount of sediment and driftwood, which are produced in numerous landslides anddebris flows owing to severe rainfalls. Sediment and driftwood carried by flood flows worsen
damage by causing river channel variation and closure. Predictions indicate that the intensity ofrainfall is likely to increase temporally and spatially due to climatic change and thus that suchflood hazards may occur more frequently. To address this type of flood hazards with runoffs ofsediment and driftwood, tools for river channel design should be developed. Focusing on suchcircumstances, ICHARM formed a research group with domestic researchers in this area andheld the first research meeting on January 25 and 30 and the second research meeting on May
25 and 28 in 2018. The participants discussed the results obtained by each researcher andclarified the applicability and issues of existing tools and methods that may be useful tosimulate and evaluate floods with sediment and driftwood.
Concurrently, the committee on hydro-science and hydraulic engineering held a workshop on
September 11, 2018, to discuss and summarize research findings and their applicability and set a
direction for future research regarding debris flows, river bed variation due to sediment runoff,and rainfall events caused by climatic change. The workshop consisted of researchers’ reports
and panel discussions. The following topics were chosen for the report session:
・ Actual conditions and technological issues derived from flood and sediment-related
disasters resulting from the Northern Kyusyu Severe Rainfall in July 2018 (Dr.
AKIYAMA Juichiro, professor emeritus, Kyushu Institute of Technology)
・ River planning and management in view of sediment runoff from mountains (Dr.
7

FUJITA Masaharu, professor, Kyoto University)
・ Evaluation of debris-flow behavior and sediment-driftwood runoff (Dr. TAKEBATASHI
Hiroshi, associate professor, Kyoto University)
・ Scaling of target phenomena and associated modelling, and a simple numerical method
for evaluating three-dimensional open channel flows (Dr. UCHIDA Tatsuhiko, associate
professor, Hiroshima University)
・ Prediction of sediment transportation and channel changes (Dr. SHIMIZU Yasuyuki,
professor, Hokkaido University)
・ Change of the severe rainfall pattern resulting from climatic change (Dr. YAMADA
Tomohito, associate professor, Hokkaido University)
・ Unified method for evaluating flood flows with sediment transportation and channelchanges (Dr. EGASHIRA Shinji, research and training advisor, ICHARM)
In the panel discussion, moderated by Prof. KOIKE Toshio, the director of ICHARM, theparticipants discussed the conditions of severe rainfall and corresponding flood andsediment-related hazards, qualitative resolutions of hazard prediction and evaluation methods,
and a suitable research system. The discussion confirmed that analyses and predictions ofrainfall occurrences and characteristics suggest that severe rainfall tends to increase its
frequency and areal locality. In fact, the occurrence of sediment-related flood hazards has been
increasing in local areas as experienced in the Hokkaido-Tohoku severe rainfall event in 20l7
and the Northern Kyushu severe rainfall event in 2018. In these events, the river channels
clogged and changed drastically owing to supplies of sediment and driftwood, which worsened
damage severely. The panel proposed developing methods for river channel design as well as forthe delineation of hazardous areas in order to prepare for such hazards. In response to this
proposal, the panel discussed, together with the attendees, the current state of the existingmodels for evaluating landslides and debris flows and their runoff processes involving
driftwood, as well as the relation of resolutions and objectives in their predictions, and finallyproposed methods to treat these sediment processes occurring at different scales of basin, slope,
stream, and reach. A numerical model to evaluate local flows in steep open channels was also
proposed, which is useful for designing hydraulic structures.
In addition, the participants discussed issues arising in applying the methods to actual cases,
as well as how the research system should be organized and how research findings should be
implemented in society. Although a flood flow, for instance, can be evaluated at the reach scaleusing the depth-averaged Reynolds equation and corresponding sediment-transport anddriftwood models, the computed results depend largely on the upstream conditions employed
for sediment and driftwood supplies. To specify their boundary conditions reasonably,
evaluations need to be done on the spatiotemporal transport processes of sediment anddriftwood resulting from landslides and debris flows. Thus, to understand such compound8phenomena, collaboration with associated research fields is essential. The panel proposed
coordinating a collaborative research system in which hydraulic engineering and erosion control
engineering will play the leading role while cooperating with meteorology, forestry, geology,
geography, and geotechnical engineering. It also proposed facilitating educational interactions
among individuals in different areas of research and stressed that close cooperation between theriver and Sabo research groups is indispensable to implement ideas in society.
2.4 New Ph.D. Training for “Water and Disaster” Policy Leaders in Collaboration with GRIPS
In 2015, the international community agreed on the Sendai Framework for Disaster Risk
Reduction, the Sustainable Development Goals, and the Paris Agreement. In December 2016,
the UN General Assembly adopted the Decade of Water for Sustainable Development. These
processes have led to the development of a framework for creating a society that can reduce therisk of water disasters and achieve sustainable development under climate change.
In 2010, ICHARM opened a doctoral program, “Disaster Management Program,” incollaboration with GRIPS, aiming to produce experts who can plan and practice disasterprevention and mitigation at a national level and can play a leading role in producing moreexperts in the field. As of September 2019, the program has graduated nine students with adoctoral degree.
In addition to these achievements, ICHARM and GRIPS jointly planned and created a new
doctoral program, aiming to foster specialists with expertise in disaster prevention andmitigation and policy development and implementation, capabilities to create social value, andthe leadership in planning and executing policies.
At the same time, JICA launched a new scholarship program, “Disaster Risk Reduction
Leaders Capacity Development for the Sendai Framework Implementation,” to support
international students in this new doctoral program.
The new doctoral program is targeted at executive candidates of government agencies
responsible for disaster management in 11 Asian countries (the Philippines, Vietnam, Indonesia,
Myanmar, Fiji, Sri Lanka, Mongolia, Nepal, Bangladesh, Pakistan, Iran), which arecharacterized by high natural disaster risks and for which JICA has been providing continuous
assistance in disaster prevention.
Since the program shares the fundamental concept with the Disaster Management Program,i.e., the original doctoral course ICHARM jointly offers with GRIPS, the new program has been
carried out using the framework of the original course. Since FY2018, two students have beenenrolled, using the JICA scholarship. The program will continue to accept new students.
2.5 Key activities of IFI
IFI is a worldwide framework to promote collaboration in flood management among9

international organizations such as UNESCO, WMO and UNDRR. ICHARM has been serving
as the secretariat since its establishment. In October 2016, the Jakarta Statement was adopted by
the member organizations to establish an interdisciplinary and transdisciplinary partnership for
consolidating flood risk reduction and sustainable development. Based on the statement,
ICHARM is promoting activities to contribute to integrated flood management in collaboration
with the relevant organizations of the participating countries.
As part of this effort, the Philippines, Sri Lanka, Pakistan, and Myanmar have already
decided to establish a Platform on Water Resilience and Disasters involving various government
agencies, and ICHARM has been supporting their decision as a facilitator. Further, ICHARM
has started assisting Indonesia in the establishment of a Platform.
At the GEOSS Asia-Pacific Symposium and other conferences, ICHARM has held AWCI
sessions, inviting representatives from the organizations of the Platform implementing countries
every year since 2017. In these sessions, they reported the progress of their Platform projects
and discussed how to promote a regional cooperative framework among the participating
countries.
In April 2016, the United Nations and the World Bank Group created the High-Level Panelon Water (HLPW), which consisted of 11 sitting heads of states and governments and one
special adviser. The panel was set to provide the leadership required to champion acomprehensive, inclusive and collaborative way of developing and managing water resources
and improving water and sanitation-related services. On March 14, 2018, the HLPW mandate
ended with the release of an outcome document, in which HLPW endorsed IFI’s initiative on
Platforms, saying: “Platforms on Water Resilience and Disasters among all stakeholders should
be formulated in countries to facilitate dialogue and scale up community-based practices.”

Participants in the AWCI session during the 11th GEOSS Asia-Pacific Symposium
2.6 Special lecture by Mr. Koïchiro Matsuura, the 8th Director-General of UNESCOICHARM organized a special lecture by inviting Mr. Koïchiro Matsuura, the eighth
Director-General of UNESCO, as a Research and Development (R&D) Seminar on January 16,
2019. After becoming the first Asian who assumed the top position of UNESCO, Mr. Matsuura
led the organization for 11 years from November 1999 to November 2009. During his tenure, he10carried out so many projects, including the establishment of ICHARM as a UNESCO category 2
centre in March 2006.
In the lecture, he spoke about the current global situation under the title of “Global trend andJapan.” Dividing the post-WWII era into three phases – the Cold War, America as No.1
superpower, and China’s rise and global disorder, he explained how the recent surge of
populism around the world became possible and how the power shift in Eastern Asia had
evolved over time. Referring to the fierce competition between China and the U.S., he insisted
that Japan should waste no time in meeting global expectations and playing a vital role inrestoring global order.
The special lecture was very fruitful and successful. The ICHARM auditorium was packed toits full capacity of about 70 people. Many people, including master’s and doctoral students
studying at ICHARM, listened to him intently and asked many questions after his lecture.

often suffers serious damage from flood disasters due to typhoons, such as Ondoy in 2009 andPedring in 2011, and monsoonal rainfall. Flood risk reduction and sustainable development
are critical issues in the basin. In February 2019, ICHARM developed a real-time flood
forecasting system for the Pampanga River basin on the DIAS in collaboration with the
EDITORIA, managed by the University of Tokyo, and started to provide flood forecasting
information to related organizations in the Philippines. Using 17 ground rain gauges of thePhilippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA),
hourly rainfall data are collected and accumulated on DIAS in real time and automatically
input into the RRI model developed by ICHARM.
ICHARM also developed the prototype system to upload the socio-economic, damage andhazard datasets of Davao City onto DIAS in collaboration with EDITORIA. This system hasa function to archive data with meta-information such as their element, domain, period,
spatial resolution, unit, and data-producing organization.
3.1.2 Prototype system development
ICHARM developed a prototype system for flood monitoring, forecasting, and early
warning incorporating real-time data integration techniques for various platforms (groundrainfall, GSMaP and clouds (Himawari, and re-analysis data from global models), advancemodels (e.g. WEB-RRI, ensemble rainfall forecasting), and information technologies such as
DIAS. The system is placed under test-operation from 2018 to now in Sri Lanka andinformation is shared with relevant organizations.
3.2 Risk assessment on water-related disasters
3.2.1 Development and dissemination of the Water and Energy Budget-based Rainfall Runoff
Inundation
The proper risk evaluation of flood disasters requires an analytical model that can
reproduce a flood event from runoff to flooding accurately. The RRI model developed someyears ago has been used in various regions as a simple model for calculating runoff andinundation during a heavy rainfall event. On the other hand, because it is not designed tohandle important hydrological factors, such as soil moisture, canopy interception,
evapotranspiration, and soil-vegetation-atmosphere interaction, the model has been found not
12applicable to the detailed analysis of flood and other water-related events in arid andsemi-arid areas and not suitable for the accurate evaluation of the impact of global warming
on hydrological phenomena.
ICHARM developed the WEB-RRI model to analyze water-related hazard phenomena withhigh accuracy by integrating the Hydro-SiB2 model capable of calculating dynamics of thewater and energy balance with the RRI model capable of 2D runoff / inundation calculation.
By using the new model in combination with atmospheric models, it has become possible toevaluate not only flood hazard impacts but also drought hazard impacts due to future climatechanges. We developed another model that calculates driftwood behavior as the density of
sediment using a water/sediment momentum equation. This model is suitable to reproduce
typical flood and sediment hazard phenomena in mountain rivers. We have also been making
efforts to disseminate these models by improving user interfaces and offering training
activities for users.
In addition, we built a model for predicting the dam reservoir inflow utilizing a runoff
model called the Water and Energy Budget-based Distributed Hydrological Model-snow(WEB-DHM-S), which estimates snowfall, snow cover and snowmelt quantitatively in

combination with rainfall forecasting information from ensemble weather forecasting. We are
studying the optimization of the current operation methodology for hydroelectric dams to
reduce ineffective dam discharges, improve power generating efficiency during a flood, andsecure the storage capacity of a dam reservoir after a flood.

3.2.2 Development and implementation of a method to simulate the flood flow with sedimentand driftwood
As part of technical assistance forthe “Policy Vision on Rebuilding
Flood-Conscious Societies,” ICHARM
developed a model to simulate theflood flow with sediment, which
frequently

in

both

mountainous areas and boundary areas
between mountains and floodplains. In
this model, a method was proposed toanalyze the behavior of driftwood in

driftwood in the Akatani Rivertransportation, erosion and deposition

processes. Observations found that, in the flood disaster of the Akatani River in July 2017, ahuge amount of fine sediment and driftwood from upstream affected the flood flow in
downstream areas. Numerical simulations of the Akatani River event using the proposed method
verified the method’s high reproducibility regarding the event. The simulation results are
expected to contribute to developing hazard
maps in similar areas.
In addition, the proposed model has been

discussions on disaster prevention.
3.2.3 Research on an optimized dam operation method using precipitation forecasting data
Due to climate change, events of extreme and no rainfall are predicted to become evenmore severe in the future. It is thus necessary to increase the efficiency of water use and theeffectiveness of flood control. For this reason, ICHARM developed a dam inflow prediction
14

system by integrating precipitation forecasting data estimated by an ensemble numerical
weather forecasting model and the Water and Energy Budget-based Distributed HydrologicalModel with Snow (WEB-DHM-S), which can estimate snowfall, snow cover and snowmelt.
This system was applied to the electric power generation dams in the Oi and Sai river basinsin Japan in a case study jointly conducted with electric power and consulting companies inwhich the dam inflow was estimated for several flood events in those basins and used to
optimize the dam operations in order to reduce ineffective dam discharges, increase theefficiency of power generation, and secure the reservoir volume after a flood. This study
showed the possibility that the system can contribute to maximizing the water use for electric

3.3 Monitoring and forecasting water-related disaster risk changes
3.3.1 Evaluation of climate change impact
In June 2018, ICHARM submitted the final report of the ADB Study Project “Climate
Change and Flood Hazard Simulations Tools for ADB Spatial Application Facility (SC109094REG).” The main objective of the project was to evaluate future flood inundation risk
due to climate change in the three cities of Vietnam: Hue, Ha Giang and Vinh Yen.
In this study project, four GCMs (CESM1 - CAM5, CNRM-CM5, GFDL-CM3,
MPI-ESM-LR) were selected from CMIP5 for their high expressiveness for the following six
meteorological factors in the target area: rainfall, upward longwave radiation, sea surface
15

pressure, temperature at the 850hPa surface, east-west wind, and north-south wind.
Each selected GCM was bias-corrected using the Nyunt et al. method and daily rainfall
observations at 53 ground gauges in Vietnam. Statistical downscaling (DS) was also applied
to the selected GCMs, and then the uncertainty caused by those GCMs in making future
predictions was evaluated. Dynamic DS was conducted using the WRF model ver. 3.7.1 forthe past climate and the end-of-21st-century climate of the RCP 8.5 scenario calculated by the
MRI-AGCM 3.2S model. All data and analytical tools used for the study were available on
DIAS.
In order to evaluate future
flood risk, future rainfall fromthe dynamic DS results was
inputted to the RRI model, andrainfall-runoff-inundation
analysis was conducted. The
model development was carried

Climate Change Resilience (UCCR) program in Asian 25 cities.
3.4 Support through proposal, evaluation and application of policies for water disaster risk
reduction
3.4.1 Development of a real-time agriculture drought monitoring and seasonal prediction
system
In the World Bank Brazil project (Technical Assistance in Implementing a Pilot ofAgriculture Drought Monitoring and Prediction), ICHARM developed a real-time agriculture
drought monitoring and seasonal prediction system for Ceará State in the Brazilian Northeast.
The DIAS collects and integrates three types of data: the NASA GLDAS meteorologicalglobal forcing data, the GCOM-W/AMSR2 microwave brightness temperature global data,
and the GFDL seasonal predictive global precipitation data. Using these data, ICHARM
applied the CLVDAS, which can calculate the land water cycle and the dynamic vegetation
growth, to the Brazilian Northeast and developed a DIAS 25km-gridded agriculture droughtmonitoring and seasonal prediction system (Drought system). Using a crop database of the
Ceará State (the Northeast Drought Monitor: NEDM, monitordesecas.ana.gov.br) provided by
FUNCEME, ICHARM also developed a method to estimate crop yield and the required
volume of irrigation water for Ceará State using LAI output from the drought system. The
Banabuiú River basin was
selected as the target area
becauseit

importantisahighlyarea

inmeteorology, hydrology, andagriculture.

Thehigh-spatial-resolution (1kmgrid) WEB-DHM was also
developed for this river basin.
By applying WEB-DHM to
the Banabuiú River basin,
ICHARM devised a method
to estimate 1km-gridded LAI

from WEB-DHM and CLVDAS. However, to achieve a high level of reliability for drought
information, more data were needed, such as land-cover data with a high spatial resolution
and in-situ precipitation data collected at multiple stations. In addition, researchers familiar
with local conditions should be able to work on the system. Hence, in October 2019,
ICHARM offered one-month training to study the basic theory and operation of the system
for two researchers of FUNCEME, which is a Brazilian organization that collects land-cover,precipitation and other data through meteorological drought monitoring and prediction.
3.4.2 Development of a flood forecasting system for small and medium rivers
In recent years, disasters due to torrential rainfall have become more frequent and severe in
Japan, consequently causing more human damage. At present, flood forecasting has not been
implemented for many small and medium rivers, though the water level tends to rise rapidly
in those rivers during a flood; thus, many residents living in nearby areas are more likely not
to be able to evacuate in time and exposed
to a high risk of suffering damage fromflooding.
In

collaboration

withrelatedorganizations such as MLIT, ICHARM has
been

3.5 Support for improving the capacity to practice disaster prevention and mitigation
3.5.1 Implementation of the UNESCO project “Water Disaster Platform to Enhance Climate
Resilience in Africa” (WADiRe-Africa)
In West Africa, floods in the Niger and Volta rivers cause devastating damage, including
casualties, and hinder the development of the countries in the region. For this reason,
UNESCO decided to implement measures to promptly initiate flood monitoring andforecasting systems in areas around the Niger and Volta rivers and reduce human damage byfacilitating safe evacuation based on flood information. After signing a partnership agreementwith UNESCO in the framework of the Water Disaster Platform to Enhance Climate
Resilience in Africa, ICHARM installed a flood early warning system (FEWS) for water
disaster mitigation in the Niger and Volta River basins and invited experts from AGRHYMETand VBA to Japan and provided training on the flood early warning system and flood risk
management.
On June 17 and 18, 2019, the representatives of related organizations attended a kick-off
meeting held in Lome City, Togo. ICHARM played a central role in sorting out key issues atthe local and national levels regarding flood management, data utilization, capacity
development, hydrological model development, and platform construction and finalizing the"Key

Pointsof

Lome

Declaration." Training on flood
forecasting systems and flood risk
management was conducted at
ICHARM for two African experts
in November 2019 for about one
and a half months and one moreexpert in March 2020.

provided to design Area-BCM to improve the disaster resilience of local communities.
Specifically, ICHARM develops a basin-scale and an industrial park-scale flood inundation
model to create advance risks and detailed information on the occurrence of water disasters.
3.5.3 Research on flood risk assessment for river basins in mountains and information sharing
To assist local governments in mountainous areas facing the lack of disaster information
for the safe evacuation of residents, ICHARM has been conducting research on creating new
flood risk indicators using inundation simulation results by the RRI model and improving
flood risk information sharing. For Iwaizumi Town, located along the Omoto River in Iwate
Prefecture, Japan, we proposed the introduction of “flood diagnostic charts,” which wedeveloped to evaluate flood risks of communities using eight indicators: ①Lead time before
inundation exceeds the first-floor level, ②Duration when evacuation is required during aflood, ③Maximum inundation depth in the community, ④Maximum inundation depth atevacuation shelters, ⑤Traffic disruption between the community and the municipal office,⑥Maximum number of isolated people during a flood, ⑦Number of vulnerable people
likely to be affected by a flood, ⑧Amount of debris and waste after a flood. Using these
indicators, we conducted a study on the development and application of flood diagnostic
charts, which categorize an area into several sections and indicate possible flood risks in eachsection. We drafted a manual on how to create flood diagnostic charts.
We also developed a new disaster information portal site called “ICHARM Disaster Risk
Information System (IDRIS),” which allows one-stop viewing of water-related disaster
information in the area. The system is designed not only for emergency use but also for
improving disaster prevention and mitigation in normal times. A preliminary operation of the20system has started in Aga Town, Niigata Prefecture, which is located in the middle reach of
the Agano River. The customized system of IDRIS for Aga Town was named “Aga Town
Risk Information System (ARIS).”IDRIS was awarded a prize as innovative technology by the Institute of Social Safety
Science of Japan in May 2019.
In August 2019, the test version of ARIS was opened to the public (moving to a site thatcan be viewed by general users). Through the test operation, we investigated the applicabilityof the developed system tothe actual local area. We
conducted

another

test

operation of the system in
Iwaizumi

Town,

Iwate

Prefecture, starting fromthe second half of fiscal
2019.

From these

test

operations, we confirmedthat IDRIS can be used

effectively by any local
governments.

3.5.4 Development of a risk communication system for enhancing public awareness ofwater-related disasters
In Hita City, Oita Prefecture, which suffered severe flood damage in 2012 and 2017, andIwaizumi Town, Iwate Prefecture, which also suffered severe flood damage in 2016, weconducted questionnaire surveys for residents from a perspective of behavioral economics.
From the viewpoint that a flood experience leads residents to take appropriate actions suchas early evacuation, we have developed simple simulation software for people to experience a
virtual inundation in a private house using a head-mounted display driven by VR technology.
After about 200 residents tried out this device, we confirmed that it can help raise people’s
awareness of the danger of floods. In addition, we are developing VR flood experience
software specifically designed for Hita City and Aga Town, combining actual cityscapes andthe results of flood and inundation simulations in the areas.
3.5.5 Study on globally-applicable multiple-risk assessment of water-related disasters and ona method of building a resilient society based on assessment results
Based on the results of a questionnaire survey in Joso City, Ibaraki Prefecture, which wasdamaged severely when the Kinu River flooded in 2015, we have been studying new21

indicators to evaluate the aspects of disaster cases that have not been evaluated adequately byexisting methods and proposed indicators to evaluate "resilience in daily life and businessactivities." The new indicators were used for the estimation of the resilience of affectedbusiness activities in "Technical Study Report on Countermeasures against Giant Disasters
that Cause National Crisis" by the Japan Society of Civil Engineers. They were also used toestimate resilience in the "Simulation tool for flood damage estimation at business activities"
published by the Economic Consortium for Disaster Management, hosted by the Cabinet
Office. In addition, we are conducting similar surveys in Iwaizumi, Iwate prefecture, which
was damaged by Typhoon No. 10 in 2016, and in Okayama and Hiroshima Prefectures, whichwere damaged by the heavy rain disaster in July 2018.
We have begun studying another set of new indicators to evaluate the effectiveness of
disaster prevention measures and investment in an easy-to-understand manner, focusing on
the level of damage at which a pre-disaster level of population and gross regional product canstill be sustained after a disaster. We are trying out the new indicators to Iwaizumi, Iwate
Prefecture, and developing an evaluation method.
3.5.6 Research on disaster response timeline and the ability of local governments to respondto water-related disasters
We developed a timeline showing a series of actions that should be taken in case ofunderground mall inundation caused by a river or urban flood in cooperation with businesses
around the West Exit of Yokohama Station in Japan through participation in the
Cross-Ministerial Strategic Innovation Promotion Program (SIP).
We analyzed disaster reports reviewing disaster response efforts in past water-related
disasters and identified problems regarding the ability of administrative staff to respond todisasters in order to improve their capacity to use a disaster response timeline effectively.
Through this analysis, we collected cases in which disaster management personnel
experienced difficulties, troubles, confusions, frustrations, and so on, in response efforts, andcompiled a “Collection of Tense Moments during Flood Disaster Response” to make it easierfor local disaster response staff to learn from past disasters.

４．Training
4.1 Master’s program: Water-related Risk Management Course of Disaster Management Policy
ProgramSince 2007, ICHARM has provided a one-year Master’s program, “Water-related Risk
Management Course of Disaster Management Policy Program (JICA Training Program:Training for Expert on Flood-Related Disaster Mitigation),” as a joint effort with JICA and
GRIPS. This program is targeted at officials of administrative organizations and designed forthem to obtain a master’s degree within a single year. In the first half of the course from
October to March, the classes consist mostly of lectures; in the second half from April to theend, students work on research and graduation theses. In addition, several study trips are
conducted during the program for students to visit dam, river, and other management offices
around Japan, where they can learn firsthand knowledge and experience in current flood
management in Japan from experts of MLIT and other organizations.
Between 2007 and 2019, the master’s program of ICHARM graduated 139 students from 33
countries.
In September 2018, the 11th batch of 14 students from 10 countries (Bangladesh, Brazil, Fiji,
India, Nepal, Pakistan, the Philippines, Sri Lanka, Tanzania, Vietnam), who entered theprogram in October 2017, graduated with a master’s degree. In the following month, the 12th
batch of 8 students from 8 countries (Bangladesh, India, Liberia, Myanmar, Nepal, Pakistan, thePhilippines, Sri Lanka) entered the program.
In September 2019, the 12th batch of 7 students from 7 countries graduated, and in thefollowing month, the 13th batch of 11 students entered the program from 6 countries(Bangladesh, Bhutan, Brazil, Myanmar, Nepal, Pakistan).
In 2019, a paper submitted by the 11th batch student was published in the American
Meteorological Society's Journal of Hydrometeorology.
This was the first case that a master's thesis research at

ICHARM started a doctoral program, “Disaster Management Program,” in 2010 incollaboration with GRIPS to produce experts who are capable of developing policies onwater-related disaster risk management and taking the leadership in implementing them.
By the end of 2019, 11 students from 7 countries completed the doctoral program.
In September 2018, the 6th batch of 2 students graduated with a doctoral degree in disastermanagement. In October, the 9th batch of 3 students entered the program.
In September 2019, the 7th batch of 2 students graduated with a doctoral degree in disastermanagement.
Currently, 4 doctoral students (1 third-year, 3 second-year students) are studying in the
program.
Among the four students, two were enrolled in September 2018 using JICA’s newscholarship program for international doctoral students, “Disaster Risk Reduction Leaders
Capacity Development for the Sendai Framework Implementation.” This program was realized
in response to international discussion on water hazards about promoting cooperation between
policy and science. It aims to provide high-level training for individuals who are expected to24

assume an executive position of their governments in the future. It has been implemented
through coupling the ICHARM training program with the GRIPS policy program.

implemented for water disaster mitigation and conducted “Town Watching”, in which theystudied the town in groups while walking around and created disaster prevention maps so thatthey could improve the ability to plan water disaster mitigation measures.
4.3.2 Support for Malaysia’s disaster management course
The Malaysia-Japan International Institute of Technology (MJIIT), an academic entity toprovide Japanese-style engineering education in Malaysia, was officially launched in
September 2011 as part of Universiti Teknologi Malaysia (UTM). The institute opened its
fifth course on disaster risk management in September 2016, which is targeted at
middle-ranking government officials in charge of disaster management. Japanese universities
and research institutes formed a consortium to provide the institute with assistance ineducation, research, management and other areas, and ICHARM has been part of it, involvedin planning the course and sending teaching staff. ICHARM staff has so far lectured about theflood forecasting and hazard mapping. On July 25, 2018, and July 22, 2019, ten andseventeen faculty members and students, respectively, visited ICHARM and participated in
lectures on research on integrated disaster prevention and human resource development.
4.3.3 Trainings on climate change
Trainings were conducted in Myanmar, the Philippines, and Sri Lanka on climate change
prediction model analysis using DIAS climate model analysis tool. These trainings provided
an opportunity for the participants to increase the understanding of climate change impact,
and the analysis method of a climate change model using DIAS efficiently.

4.4 Follow-up Seminar for ICHARM Alumni
ICHARM has held a Follow-up Seminar once a year since 2007 in a country of graduatesfrom ICHARM educational and training programs to provide additional assistance and visit
rivers and other places with water-related problems. This annual meeting is a great opportunity
for ICHARM to see how graduates are using the knowledge and skills they learned at ICHARM
and to share issues they face in their practices. Such information is used to improve ICHARM’straining programs and enhance its research activities.
From January 23 to 24, 2019, the FY2018 Follow-up Seminar was held in Kathmandu, Nepal,
with 25 participants, including officials from the Nepalese government, and the Embassy ofJapan in Nepal, JICA Nepal Office, and ICHARM. The seminar consisted of presentations anddiscussions and a field trip to flood-prone areas in the Jhiku River.
The FY2019 Follow-up Seminar was held on February 12 and 14, 2020, in Colombo, Sri
Lanka. A total of 32 people participated from the Irrigation Department, the Department of
Irrigation-Eastern Province, the Sri Lanka Land Reclamation and Development Corporation, theEmbassy of Japan in Sri Lanka, JICA Sri Lanka Office, and ICHARM. The first day was spentfor presentations and discussions, and the second day for a field trip to the Maha River near
Negombo and the Deduru River near Chirawa, where the participants observed the situation ofriverbank erosion.
4.5 Internship

５．Information networking
5.1 International Flood Initiative
5.1.1 Global activities
A new strategy and an action plan of IFI were approved at the UNESCO-IHP
Intergovernmental Council held at the UNESCO headquarters in June 2016. At the side eventof the 8th HELP meeting in Jakarta, Indonesia, in October 2016, the Jakarta Statement was
adopted by the member organizations of IFI to establish an interdisciplinary andtransdisciplinary partnership for consolidating flood risk reduction and sustainable
development. The Jakarta Statement explains the current status of water-related disaster risk
reduction and sustainable development and presents the direction and actions to take for thepromotion of those two ultimate goals. Based on the statement, ICHARM is promoting the
global effort to establish Platforms on Water Resilience and Disasters.
ICHARM participates in various international conferences. By utilizing these opportunities,
ICHARM organizes sessions and side events to promote IFI activities in general and Platform
activities in the IFI implementing countries.
In June 2018, ICHARM organized a side event at the UNESCO-IHP Intergovernmental
Council meeting in collaboration with UNESCO, WMO and IAHS. ICHARM also held
sessions at the 8th Civil Engineering Conference in the Asian Region (CECAR8) in Tokyo,
Japan, in April 2019 and at the panel on water and disasters during the UNESCO
International Water Conference in Paris, France, in May 2019. The sessions were great

ICHARM also sent researchers to other IHP-related conferences to speak about its
activities and exchange views and ideas with other participants.
During the United Nations High-level Political Forum on Sustainable Development(HLPF), held in July 2018, WMO and UNESCO-IHP organized a side event, “Hydrology
Towards Sustainable Resilient Societies,” on July 10, which ICHARM joined as a partnerorganization of UNESCO and WMO. HLPF is the main United Nations platform onsustainable development and plays a central role in the follow-up and review of “the 2030
Agenda for Sustainable Development: Sustainable Development Goals (SDGs)” at the global
level. At this side event, ICHARM made a presentation on “Progress of the Platforms on
Water Resilience and Disasters in the IFI active countries.” ICHARM also explained how
Japan had revised its policies and laws to cope with the changing patterns of climate andwater-related hazards in recent years and stressed the important role of science and31technology in water-related disaster risk reduction.
ICHARM convened the “Panel on Water and Disasters” on May 13, 2019, with HELP at
the International Water Conference, which UNESCO organized for the first time. Two
ministers, the minister of Land Management, Water and Sanitation Services from Botswana
and the minister of Water andSanitation

from

BurkinaFaso,joined this panel and introduced
issues on water and disasters in theircountries. ICHARM explained theend-to-end approach to achieving
sustainablesocio-economic

development against water-related
disasters and climate change, and
the

ICHARM researchers, including the director, the research and training advisor, chief andsenior researchers, and research specialists, were invited by overseas organizations anduniversities to give lectures and presentations or join discussions as a panelist on flood
forecasting technology, flood forecasting and warning, and hydrological models.
5.3 Contribution to the Typhoon Committee38

TC is an intergovernmental community jointly organized in 1968 by UNESCAP and WMO topromote and coordinate the development and implementation of plans to minimize human andphysical damage caused by typhoons in the Asia-Pacific region. The members are composed ofgovernmental organizations of 14 nations and territories in East and Southeast Asia. The
committee consists of four Working Groups of Meteorology, Hydrology, Disaster Risk
Reduction, and Training and Research, each of which works on its projects independently.
Integrated Workshops and Annual Sessions are also held periodically. A chief researcher of
ICHARM has been the chair of WGH. As an AOP1 of the WGH, ICHARM implemented the“Flash Flood Risk Information for Local Resilience” project during the 2017-2019 period incollaboration with the WGH members. In 2019, ICHARM started another project, “Platform of
Water Resilience and Disasters under the International Flood Initiative,” as an AOP7. The
following lists the TC-related meetings held in the 2018-2019 period:
・ The 13th Annual Meeting of Working Group of Disaster Risk Reduction and the Advisory
Working Group (Ulsan, Korea; May 29-June 1, 2018)
・ The 7th Annual Meeting of WGH (Tokyo, Japan; October 9-12, 2018)
・ The 13th Annual Integrated Workshop (Chang Mai, Thailand; November 5-9, 2018)
・ The 51st Annual Session (Guangzhou, China; February 25-March 2, 2019)

51st TC Annual Session (Guangzhou, China in February 2019)
The 7th Annual Meeting of WGH held in October 2018 was co-organized by MLIT and
ICHARM. It was the first time for Japan to host a WGH meeting after 2012, when WGH started
to meet annually. The director general of MLIT gave an opening address, and the ICHARM
director delivered technical presentations.
In the 13th Integrated Workshop held in November 2018, ICHARM proposed a new AOP on“Platform on Water Resilience and Disasters under the International Flood Initiative”. In
39response, the WGH members joined an IFI meeting held in February 2019 in the Philippines, amember of TC, to observe discussions on the progress of IFI Platform activities. The 51st
Annual Session in February 2019 approved the action and budget plans for the new project of
WGH, i.e., Platform on Water Resilience and Disasters under International Flood Initiative, as
an AOP7. The session also appointed a chief researcher of ICHARM as the new chair of WGH
after the predecessor, who was also a chief researcher of ICHARM.
Playing an important role in TC, for example, by continuously assuming the chair of WGH in
collaboration with its members such as MLIT and JMA, ICHARM actively participated in the
Annual Meeting of WGH in October 2019 and the Annual Integrated Workshop in November
2019.
The Panel on Tropical Cyclones (PTC) for the Bay of Bengal and the Arabian Sea targets theregion prone to tropical cyclones as an intergovernmental body of WMO and UNESCAP justlike TC targeting the typhoon-affected region. Since ICHARM has recently been working on“Platform on Water Resilience and Disasters under the International Flood Initiative” as an
AOP7 of TC-WGH, it also supports the establishment of an IFI Platform in Myanmar, Sri Lanka
and Pakistan, which are members of PTC. On September 9-13, 2019, the 46th session of PTC
was held in Nay Pyi Taw, Myanmar, where ICHARM provided a presentation on its activities,
including those related to IFI. During the session, the participants discussed how to develop
regional collaborative activities and expressed their expectations for ICHARM to build a bridge
between the PTC and TC through IFI activities.
5.4 Leading the International Atomic Energy Agency (IAEA)/Regional Cooperative Agreement(RCA) RAS/7/030 Project on “Assessing Deep Groundwater Resources for Sustainable
Management through Utilization of Isotopic Techniques” in Japan

６．Academic Field Surveys in Japan and Overseas Countries
6.1 Field Surveys of the July 2018 Torrential Rain Disaster in Western Japan
From July 5 to 7, 2018, continuous rainfall in western Japan induced numerous landslides,
debris flows and floods with a massive transport of sediment in several prefectures of the
Chugoku and Shikoku regions, including Hiroshima, Okayama, and Ehime. Those events
caused severe damage with about 230 people dead or missing throughout Japan. ICHARM has
been studying public responses to disasters resulting from levee breaches. In addition, focusing
on floods with massive sediment supplies, which often take place with landslides and debris
flows, ICHARM has conducted field investigations to identify the geomorphologicalcharacteristics of this type of floods and evaluated them from an engineering viewpoint.

6.2 Field Surveys of Disaster Damage by the Torrential Rainfall Due to Typhoon No.19(Hagibis)
On October 12, 2019, Typhoon No.19 (Hagibis) hit the Izu Peninsula and broughtrecord-breaking heavy rainfall over a wide area of Japan. At one location, the accumulated
precipitation exceeded 1,000 mm. At many locations, mainly in eastern Japan, the 3-, 6-, 12-,46

and 24-hour precipitations reached a record high, causing floods with a massive transport of
sediment, as well as landslides and debris flows. Considerable damage resulted, including 102
people dead or missing throughout Japan. Since this event, ICHARM has been conducting
research on floods with a massive transport of sediment, which have been frequent in recent
years, to clarify their mechanisms and phenomena and study effective methods for sharing
information in the event of such a disaster.
(The damage statistics cited in this section is quoted from the Disaster Report issued by Cabinet
Office on December 12, 2019.:
http://www.bousai.go.jp/updates/r1typhoon19/pdf/r1typhoon19_42.pdf

6.3 Field Survey on Geomorphological Changes of the Sittaung River Estuary
The Sittaung River drains the area of 36,000 km2 and plays an important role in the water
resources of Myanmar. The funnel-shaped estuary had a bed and banks composed of silt-clay
particles and a shallow flow field; thus, active sediment transportation takes placecorresponding to the river flow and tidal currents, resulting in sand bar deformation and channelchanges with bank erosion. In particular, bank retreat occurs at the rate of 1,000 m/year in some
sections where the retreat is most active.
Such bank erosion has caused losses ofagricultural

land

and

settlements.

ICHARM has studied the bank erosion andassociated issues with the Directorate of
Water Resources and Improvement ofRiver Systems (DWIR) since 2017 throughdata

analyses,field

surveys,flume

experiments and numerical simulations.

The research activities have led to important achievements such as a tidal-current model, amethod for evaluating sediment transportation and channel changes, the relationship between
the periodicity of bank line changes and associated village formation and disappearance.

6.4 Field Survey on Sediment Transport Processes and Associated Changes in Coastal
Geomorphology in the Tonlé Sap Lake
This study has been conducted to investigate the role of riparian sediment transportation in
the geomorphic development of the Tonlé Sap Lake coast, focusing on the Stung Sen River andthe corresponding coastal area of the lake. The study is supported by the Department of Geologyof Ministry of Mines and Energy of Cambodia with partial financial assistance from the Japan
Society for the Promotion of Science. ICHARM has investigated the physical characteristics ofriverbed material and sediment transport processes along the river reach in relation to seasonalchanges in the lake water level and obtained interesting results. Morphologically, the river
channel can be divided into three sections: the natural channel section, the channel section
influenced by the backwater effect of the lake, and the submerged channel section by the lakewater. The natural channel section ischaracterized by a meandering channel

7.3 Virtual flood experience for the public
To achieve effective water-related disaster management, it is critical that each citizen keeps
in mind that a flood disaster can occur to anybody and trains themselves to take appropriate
evacuation actions when noticing signs of a disaster or receiving warnings. ICHARM has been
studying practical disaster management measures to support citizens in attaining those goals and,as part of such effort, developed a virtual flood experience system using VR technology.
VR provides an opportunity for people to virtually experience water-related disasters before
they actually occur. Since not many people experience a flood in reality, VR is very useful forthem to see and feel what a flood would be like before they experience a real one.
In 2019, we conducted a questionnaire survey on VR at two outreach events held by
ICHARM and PWRI. In those events, the participants used VR and experienced a virtual flood
situation, in which they tried to evacuate to the second floor. After collecting 226 answers(adults: 111, children: 115), we statistically analyzed them to see whether the VR experience
had any effect on how people view a flood. We also compared adults and children in the effectof the VR experience.

Virtual flood experience
The results found no difference in the perception of a flood between adults and children. All
age groups answered that being in a flood situation was very scary, even knowing that it was
only virtual. Merely 40% were worried about a future flood before the virtual flood experience,but the figure went up to 80% after the VR experience. These results indicate that VR can be aneffective tool to help people realize the destructive nature of floods and the importance of51

preparing for future events.
7.4 Newsletters and website
The ICHARM Newsletter has been published four times
a year since March 2006 to publicize its activities ofresearch, education and training, and local practice projects,
as well as a list of published papers. During the 2018-2019
period, the newsletter was published eight times from No.
48 of April 2018 to No. 55 of January 2020. The number ofsubscribers has reached over 5,000. Since No. 47 ofJanuary 2018, the online survey on the newsletter has
started. The results have been published in the newsletterand used to further improve the contents. In addition, the

ICHARM Newsletter No. 54

table of contents has been added to improve theaccessibility to each article, and more efforts have been made to diversify news topics bycollecting contributions from people outside the institute. In 2019, for example, the newsletter
started to include contributions from graduates of ICHARM educational programs to enrich thecontents, diversify the topics, and establish and maintain a continuous relationship with them.
ICHARM’s website has gone
through a great renewal. A new
