Message from Director
Move on to a different dimension from 102 to 103
A hilly and mountainous area in northern Kyushu Island of Japan was seriously damaged inJuly 2017 by extremely heavy rainfall reaching
up to 900mm/12hr, which was estimated using
a radar-rain gauge network. Debris flows occurred throughout most of the area, covered
with thick decomposed Granodiorite. A hugeamount of sediment and fallen trees flowed
down with a violent torrent and changed thetranquil landscape of the valley plain dramatically. The narrow river channels were completely
filled with the sediment. Then, the flood flow Director Toshio Koike at Global Forum on Scienceand Technology for Disaster Resilience 2017with the driftwood spread while heaving up and(November 2017)
down across the valley plain, claimed human lives, and destroyed houses, farmland
and roads.
According to Chronicles of Japan, one of the country’s oldest histories, a royal palace was once constructed in the damaged area in the year 661. Since then, people
there have been constructing infrastructure for livelihood and production, building
communities, and developing and nurturing a culture for so long. The valley plain
has been formed through geomorphological processes as occurred in 2017 without any doubt. A geographer says, “This is a textbook case of microtopography
reformed by floods and sediment.”
In the recent flood management of major rivers in Japan, structures are planned forfloods of 80-200 year return period. The IPCC 4th Assessment Report, publishedin 2007, asserted that the warming of the climate system due to anthropogenic
green-gas emissions was unequivocal. Exactly the same expression was used in the
5th report in 2014. Associated with the climate change, heavy precipitation eventsare projected to increase in frequency, intensity, and/or amount. Actually, we arenow experiencing heavy rainfall events of an unprecedented scale with the return
period shifting from the 102 order to 103; events of that scale may cause far more
drastic topographical modifications. The impacts of the changes can be even more
serious in hilly and mountainous areas with smaller basin area and shorter flood
travel time. All hydrologists are supposed to know these processes well. I am deeply ashamed of immature scientific knowledge and low-level actions against thechanges. By developing our scientific imagination, we should urgently take up thechallenge of building a resilient society to disasters of a different dimension.

The International Flood Initiative (IFI) is a worldwide framework to promote collaboration in flood management amonginternational organizations such as UNESCO, the World Meteorological Organization (WMO), the United Nations University (UNU) and the United Nations International Strategy for Disaster Reduction(UNISDR). ICHARM has been its secretariat since the establishment of IFI.
In October 2016, the Jakarta Statement towards an interdisciplinary and transdisciplinary partnership to consolidate flood risk reduction and sustainable development, was adopted by the member organizations of IFI. As part of this effort, thePhilippines, Sri Lanka, Pakistan and Myanmar have already decided to establish
a Platform on Water and Disaster involving various government agencies, and
ICHARM has been supporting their decision as facilitator. This article reports theactivities of IFI at national, regional and global levels, which ranges widely fromstrengthening collaboration among international organizations to supporting individual nations in water-related disaster risk reduction.

Global activities
Among the global activities, three international conferences convened in 2017
should be addressed: the 3rd UN Special Thematic Session on Water and Disasters,
the 7th International Conference on Flood Management (ICFM7), and the World
Bosai Forum.

Ameenah Gurib-Fakim delivered a keynote speech. His Imperial Highness Crown
Prince of Japan joined the conference through video and made a keynote lecture
on water and disasters. Japan’s Liberal Democratic Party Secretary General Toshihiro
Nikai was also at the conference among the keynote speakers. The plenary session
stressed the importance of awareness and dialogue to address the issues of waterand disasters for successful implementation of the new international decade for
Action - Water for Sustainable Development 2018-2028.
In the afternoon, the Special Session on Science and Technology was held, andDirector of ICHARM Toshio Koike served as a co-chair (photo 1). The session discussed a broad range of topics on water and disasters: a mechanism to promote
the concept of Alliance of Alliances on Water and Disasters, sediment disaster
research, research foundation to promote investment and financing, response to
Water-related Disasters, as well as Platforms on Water and Disaster, whose establishment has been underway in several nations with help from ICHARM. The representatives of WMO and UNESCO-IHP also proposed further promotion of theinternational initiatives in the field. The director of ICHARM wrapped up the session
as co-chair with a summary of the discussions.
ICFM7 was held at Leeds University in Britain, and the director of ICHARM chaired
an IFI special session, which took place on September 8. The session was attended
by many experts including Director of WMO Climate and Water Department Johannes Cullmann through a teleconference system. Dr. Abou Amani, the chief ofSection of UNESCO-IHP, Prof. Eduardo Mario Mendiondo of Centro Nacional de
Monitoramento e Alerta de Desastres Naturais (CEMADEN), and Researcher Mamoru Miyamoto of ICHARM made a presentation on the importance of establishing a
Platform on Water and Disaster in each country. Other speakers also delivered very
interesting presentations regarding the role of IFI and the need for water-related
disaster risk reduction in the world, Africa, Latin America, and Asia. The presentations stimulated insightful discussions that can lead IFI’s platform project, which iscurrently being implemented mainly in Asian countries, to a global effort covering
Africa and Latin America.
During the conference, the ICFM special committee met on September 4 and 7,
and proposed that the IFI special session be officially included in the plenary session at ICFM8 scheduled in 2020, though it was a parallel session at ICFM7. Thisshows high expectations of the global community towards IFI.
The World Bosai Forum was held in Sendai, Japan. ICHARM organized a technicalsession on November 28, and the director of ICHARM served as the moderator. The
session discussed the project of a Platform on Water and Disaster from multiple
perspectives of ICT, economy, community and dynamics while the invited panelists
from the Philippines, Sri Lanka, Pakistan and Brazil spoke about the present situation and efforts of their countries regarding disasters and their management. Prof.

Research

Introduction of ICHARM research projects
ICHARM sets three principal areas of activity: research, capacity building, and information
network. It plans and implements projects in these areas in order to fulfill its mission, always
keeping in mind “localism”, a principle with which we respect local diversity of natural, socialand cultural conditions, being sensitive to local needs, priorities, development stage, etc.,
within the context of global and regional experiences and trends of disasters.
At present, ICHARM conducts innovative research in the following five major areas:(1) Data collection, storage, sharing, and statistics on water related disasters(2) Risk assessment on water related disasters(3) Monitoring and prediction of changes in water related disaster risk(4)Proposal, evaluation and application of policy ideas for water related disaster risk reduction(5) Support in constructing the applicability of water-related disaster management

dry season. Therefore, topography in the lake coast has been constructed by theinteraction of sediment supply by inflowing tributaries, cyclic water level changes,
and flood flow near the lake coast. Evidently, sediment supply, transport and accumulation by inflowing tributaries play an important role in constructing the coastal
topography of the lake; however, lake level changes, particularly as a result of the
backwater effect of the lake, are also an essential component in the topographicaldevelopment of the lake coast. This study revealed the effects of lake level changes
on sediment transport by the Stung Sen River, which has the largest drainage basin (16,000 km2) in the Tonle Sap systems, focusing on modern channel bars in its
lower reach.
Fig. 2 shows channel bars that appear in the same place every year at the studysite near Kampong Thom city, which is located at 83 km from the lake. There is accommodation space for sediment accumulation at a meandering channel bend,
and a concave bank bench develops with recent alternate layers of silt and sand,as shown in Fig. 3. Fig. 4 illustrates calculated sediment transport capacity in the
study area on the basis of the water surface profile. The sediment transport capacity declines as the flow discharge decreases and the water surface level of the lake
increases. For example, the bed shear stress drops to a 60% level at the lowest flow
discharge of 200 m3/s. As sediment transport capacity depends on the n-th powerof bed shear stress (n > 1), the sediment transport capacity can decrease by morethan 60% in this case. Our investigation revealed that the accumulation of the alternate sediment layers and the development of the channel bar at the study sitewere accelerated by the decreased sediment transport capacity due to the severe
backwater effect particularly in the late rainy season, as well as due to the horizontal sediment transport caused by meandering channel bends.

Forecasting in the Upper Indus Basin considering snow and glaciermeltwater

LIU Tong, Research specialist

専門研究員

Flooding in the monsoon season is a challenging problem in the Indus River, Pakistan. The operational flood early
warning system, known as Indus-Integrated Flood Analysis System (Indus-IFAS), was established by ICHARM througha UNESCO project in conjunction with Japan International Cooperation Agency (JICA). IFAS provides the Flood Forecasting Division (FFD) of the Pakistan Meteorological Department (PMD) with scientifically based flood forecast
information along the main stream of the Indus River and the Kabul River, which originates in Afghanistan and is
known as one of its main tributaries[1]–[5]. This system can forecast the peak discharge with hours of lead time withboth ground-observed and satellite-based rainfall as input. The objective of this study is to improve the simulated
discharge by the current flood forecasting system in the Upper Indus Basin by developing and applying degree–day
method for simulating glacier and snow meltwater reliably with limited observed meteorological data (Fig. 1)[6].
The simulated discharge with glaciermelt and snowmelt
could capture the variations of the observed discharge
in terms of peak volume and timing, particularly in theearly monsoon season. It can be concluded that the snow
and glacier meltwater methods are effective when precipitation is properly observed. According to the analysis,
glaciermelt and snowmelt contribution at Skardu was estimated to be 43.2–65.2% of the average daily dischargeduring the monsoon season in 2005–2012. Glacier andsnow meltwater occurring between Skardu and P. Bridge
was estimated to be 22.0–29.3% of the average daily discharge observed at P. Bridge. The glaciermelt and snowmelt originating from sub-catchments between P. Bridge
and Tarbela were calculated to be 6.3–19.9% of the average daily discharge observed at Tarbela.

A three-member team from ICHARM composed of Senior Researcher Atsuhiro Yorozuya, Researcher Hiroshi Koseki (PWRI,
Hydrologic Engineering Research Team), Research AssistantAhmad Ali Gul visited Bangladesh from August 19-26, 2017 to
conduct field investigations and measurements in collaboration with Bangladesh Water Development Board (BWDB) in
the Jamuna River at Bahadurabad. Mr. Tanjir Saif Ahmed, SubDivisional Engineer at the BWDB and an ICHARM alumni, also
accompanied the team during the measurement exercise.
The processes of sediment transport and riverbed evolution
vary in rivers where sediment transport is dominated by bedload or by suspended load. While a lot of research has been
conducted in understanding sediment transport processes in
bedload-dominated rivers through observation and numericalsimulation, similar research is uncommon for suspended-sediment-dominated rivers. The measurements in Jamuna River,which is a large, braided, suspended-sediment-dominated river are therefore an important part of ICHARM research activities. The Jamuna river flows into Northern Bangladesh from
India (as Brahmaputra) having a catchment area of 583,000
sq. km and a length of 2,850 km before entering Bangladesh.
High flows occur between April and October during monsoon
season with a mean peak discharge around 69,000 m3/s andmaximum recorded peak at 102,535 m3/s (Sept, 1998). Field
measurements were conducted at Bahadurabad section which
is located 30 km downstream of the Teesta-Brahmaputra

confluence (Figure 1). The measurement exercise focused on
the suspended sediment generation and distribution, and bedform changes during high flows. The measurement
setup consisted of a TRDI RiverRay aDcp mounted on a tethered boat, along with turbidity meter, water sampler, anddredge sampler for point measurement of turbidity, suspended sediment and bed material composition respectively.
Dense measurements were also conducted in various parts of the Bahadurabad section, including locations where extensive boil ejection was observed at the river surface. Boil occurs due to turbulence on the lee side of dune formations which can resultin ejection on the surface of the river (as shown in figure 2). Measurements of flow
velocity distribution, bed form, bed and suspended sediment composition were madeusing the measurement setup described earlier, to help create a better understandingof the boil phenomenon and its role in generation of suspended sediment.

exercise was around 61,300 m /s with a decreasing trend as the flood wave receded (Figure 2). Suspended Sediment
Concentration (SSC) was calculated using aDcp acoustic backscatter, using equation by Kitsuda et al, 2006 calibrated
by Turbidity measurements. Using velocity measurements at each depth interval and multiplying with calculated
SSC, suspended sediment discharge at Bahadurabad was calculated as 24.87 m3/s (Figure 3). Bedload discharge at
Bahadurabad, calculated using Egashira et al, (1997) and using bedload velocity measured by the aDcp was calculated as 1.13 m3/s. The ratio of suspended sediment discharge and the bedload discharge was 22.01 which is inagreement with the findings of Okada et al, 2016 also from Jamuna River. The data collected and associated analysis
is part of ongoing research exploring suspended sediment characteristics and generation mechanisms in suspended

ICHARM is involved in the Cross-ministerial Strategic Innovation Promotion Program (SIP), Japan’s national project led by the Council for Science, Technology andInnovation, and is assigned to study disaster response and risk reduction support
technology for multiple-hazard disasters in the Tokyo metropolitan area. This particular research project is led by Kogakuin University for the period 2014-2018 as
one of the research tasks aiming at the development of applications for regional
disaster response as regional collaboration, which is categorized in the Enhancement of Societal Resiliency against Natural Disasters. ICHARM participates in thisresearch project as a joint research organization. The goal of the project is to develop an application to support smooth disaster response by quickly delivering earthquake and flood information to local businesses and other stakeholders according
to an action plan prepared for emergency.
On September 26, 2017, the research project team including ICHARM held a workshop for businesses around the West Exit of Yokohama Station. The West Exit area
is one of the study areas and is considered to be at high inundation risk because it
is located on the prefecturally-managed Katabira River. The workshop was attended
by major businesses in the underground shopping mall and in its surrounding area,
which jointly organize a community council for fire and disaster management. The

purpose of the workshop was to have a concrete image of how it would be if inundation actually occurs and discuss how businesses should respond to the situation
and what problems may arise during the response efforts.
In the workshop, the timeline of events was presented, starting from the landfall ofa typhoon, followed by evacuation preparation, evacuation of elderly and other vulnerable citizens, evacuation advisory, evacuation order, flooding, and restoration inthis sequence. The participants discussed what each business needs to do in order
to collect information, prevent inundation, lead evacuation, and make decisions onwhether to continue or stop business activities (Figure 1), as well as whether businesses need support for disaster response using disaster management applications.
ICHARM, in charge of preparing an inundation scenario, also provided images ofpossible inundation around Yokohama Station (Figure 2), created using a 3D spatialmodel in collaboration with Asia Air Survey Co., Ltd. The simulation helped the participants to have a common image of disaster damage that the area may actually
suffer.

Remote Sensing Technique. In November, Mechanics of Sediment Transportation
and Channel Changes by Prof. Egashira and Practice on Forecasting and Inundation Analysis also started. Since this master’s degree program is a one-year course,
the schedule can be extremely tough particularly in the first half of the year; thestudents sometimes have to attend four lectures a day. However, they are so motivated that they have scarcely had any problems managing the course work.
On October 12, the students participated in a lecture at Tokyo and visited the
Honjo Life Safety Learning Center of the Tokyo Fire Department with the studentsof the International Institute of Seismology and Earthquake Engineering (IISEE). It
was planned to promote the exchange between the students of IISEE and ICHARM,
as their master’s courses are both part of the Disaster Management Policy Program(DMP), which the two institutes collaborated to establish with JICA and the National
Graduate Institute for Policy Studies (GRIPS).
On October 25-27, the students went on the first study tour to the Kinu River basinin the northern Kanto region to see progress in recovery from the damage causedby the Kanto Tohoku heavy rain in September 2015. They visited restoration sites
along the Kinu River and the Kawaji and Ikari dams located in the upper Kinu River.
On November 10, the students visited the Geospatial Information Authority of Japan (GSI) and learned the roles of GSI in disasters.
From November 27 through December 8, the students attended the two-week intensive lectures at GRIPS.
The second study tour took place on December 13-15. The students visited themulti-purpose retarding ponds and Kawawa retarding basin in the Tsurumi Riverbasin in Kanagawa Prefecture and the Metropolitan Area Outer Underground Discharge Channel in Saitama Prefecture to learn about flood control measures specifically designed to protect urban areas. They also visited the Kanto Regional Development Bureau of the Ministry of Land, Infrastructure, Transportation and Tourism(MLIT) and listened to lectures about river management in general and the disaster
response efforts during the 2015 Kanto Tohoku heavy rain.
The major activities of this M.Sc. program for the last three months, which havebeen reported here, are also posted on the ‘ICHARM training course’ Facebook

The seminar is usually attended by former participants and students of ICHARM education and training programs, offering lectures
on new development and technology in the field of disaster management and astudy tour to local sites having water-related problems.
This year’s Follow-up Seminar was held on December 13-14, 2017, in Yangon, Myanmar. The seminar was attended by 28 participants from the two countries. From
Myanmar, Mr. Htun Lwin Oo, the director general of the Directorate of Water Resources and Improvement of River Systems, participated along with other officials
from the Irrigation and Water Utilization Management Department, Relief andResettlement Department, the Yangon Technological University, and a JICA local office. Participants from ICHARM were Director Toshio Koike, Deputy Director Hisaya
Sawano, Research and Training Advisor Shinji Egashira, Chief Researcher Tetsuya
Ikeda, Chief Researcher Yoshio Tokunaga, and Assistant Maiko Sano.
On the first day, a series of presentations were delivered from both sides. ICHARM
researchers spoke about recent activities of the International Flood Initiative andthe Asian Development Bank project and gave a technical lecture. From the Myanmar side, seven former master’s students and seven former training participants of
ICHARM educational and training programs made presentations on their activities
and advice for ICHARM to improve the programs.

Follow-up seminar in Yangon, Myanmar

Participants in follow-up seminarOn the second day, the researchers of ICHARM visited Nyandong near Yangon with
14 seminar participants. At the first place of Nyandong, they listened to explanation about irrigation and flood-control structures installed along the Line River, atributary of the Ayeyarwady River, and how thearea will be in case of a flood. The party also
visited a few other places in Nyandong andlistened to local river managers explaining thecurrent situation and their activities. One waswhere floodwaters overtopped the levee, andthe other was where the river bank erosion is inprogress near the piers of a bridge across theSite visiting at Nyandong
Ayeyarwady River.
The two-day seminar was very informative, gathering scientists and engineers inwater-related disaster management from Japan and Myanmar. Both parties learned
a lot from each other including the current practice in disaster management andissued faced by Myanmar. The Japanese researchers were particularly interested in
the flood fighting corps system and skeleton work employed in Myanmar as flood
control measures, for those measures are just like traditional measures that havebeen widely used in Japan.

The forum was organized to recognize the importance of a solid evidence and science base for risk-informed development and investment, just as it was emphasisedat the Sendai Framework for Disaster Risk Reduction 2015–2030. The forum also
aimed to highlight the important linkages and mutual reinforcement for disasterrisk reduction with the 2030 agendas: the Sustainable Development Goals (SDGs),
the Paris Agreement on Climate Change, and the New Urban Agenda. The forum
meeting brought together scientists and researchers from universities and academic institutions, representatives of disaster risk reduction national authorities and key
United Nations and international organizations, policy makers, and other relevant
development partners. The participants were 228 from 42 countries in total.
To pursue steady implementation of the four priorities for action* of the Sendai
Framework, the forum aimed to call on all stakeholders to develop plans for thefollowing two outputs:
1) Guidelines for strengthening DRR national platforms and coordination mechanisms through enhanced contribution of science and technology; and
2) Periodic synthesis reports on the state of science and technology for reducing
disaster risk.
(*) Priority 1: Understanding disaster risk.
Priority 2: Strengthening disaster risk governance to manage disaster risk.
Priority 3: Investing in disaster risk reduction for resilience.
Priority 4: Enhancing disaster preparedness for effective response and to “Build
Back Better” in recovery, rehabilitation and reconstruction.
For this purpose, it was composed of seven working group sessions on the fourpriorities for action and three cross-cutting topics (promotion of interdisciplinary
collaboration, strengthen national platforms for more effective use of science andtechnology for disaster risk reduction in each country, and synthesis), and eachgroup produced a “Policy Brief”.
On the last day, with the attendance of H.I.H. Crown Price of Japan, the High Level
Panel session was held, attended by Mr. Hachiro Okonogi, the minister of State
for Disaster Management, Professor Juichi Yamagiwa, the president of the Science
Council of Japan, Dr. Robert Glasser, the special representative of the UN SecretaryGeneral for Disaster Risk Reduction, and other representatives from international
agencies. At the end of the forum, “Tokyo Statement 2017 -Science and technology
action for a disaster-resilient world-” was adopted.

Asia-Pacific countries are closely related
through water and many water-associatedphenomena. Water supports lives, economies and ecosystems in the region. On theProf. Koike, Director, ICHARM, the co-chair,other hand, it also causes hazards such as
and the panelists of Part 3
floods and droughts, which are exacerbatedby climate change and posing a threat to mountains, coasts, and small islands inthe region. The commonality and inter-connection of water issues in the Asia-Pacific region necessitates a holistic approach to problems emerging across the region
from mountains to islands.
In this regard, the session was a unique platform for high-level leaders and representatives of Asia-Pacific states, in which they discussed water-related disaster andenvironmental risks intensified by climate change, explored common challenges
and their solutions, and sought for collaboration in the development of effective
frameworks for action.
The session was composed of three (3) parts:● Part 1: Keynote speeches were delivered by high-level leaders: H. E. Dr. José
Ramos-Horta, the senior minister of the Democratic Republic of Timor-Leste,
the former president of Timore-Leste, and the Nobel laureate for peace prizein 1996; H. E. Mr. Keiichi Ishii, the minister of Land, Infrastructure, Transport andTourism, Japan; and H.E. Dr. Swarnim Wagle, the vice chair of the National Planning Commission of Nepal.
● Part 2: Country presentations on water and disasters were delivered in the context of climate change from seven countries of the Asia-Pacific region: Myanmar,
Bhutan, Indonesia, Japan, Korea, Sri Lanka, and Tonga.
● Part 3: Panel discussion took place, co-chaired by Dr. Kyaw Moe Oo, the director
general of DMH, Myanmar, and ICHARM director Toshio Koike. The co-chairs andfive panelists talked about problems presented in the country presentations andhighlighted key issues from their expertise.
The outcomes of the session were reported by Chief Researcher Tetsuya Ikeda on
the afternoon of December 12 along with those of the other sessions. Finally, theYangon Declaration was adopted at the closing plenary.

Meeting on a new SATREPS project
The Japan Science and Technology Agency(JST) and JICA is planning to launch a newresearch project of the Science and Technology Research Partnership for Sustainable Development (SATREPS) from 2018 inThailand, aiming at the implement of “AreaBusiness Continuity Management (AreaBCM)” for the enhancement of resilience ofindustry complexes in Thailand. As part of Meeting at the College of Population Studies of
Chulalongkorn University
this effort, a project planning meeting washeld at Chulalongkorn University in Thailand on October 10, 2017, and Researcher
Mamoru Miyamoto participated in the meeting along with other Japanese experts
including Prof. Kenji Watanabe*1, Prof. Haruo Hayashi*2, Dr. Ryohei Misumi*3, andDr. Hideyuki Kamimera*4. The representatives of Thailand were from the Collegeof Population Studies of Chulalongkorn University, the Thai Environmental Institute, the Urban and Local Planning Bureau of the Public Works Department of the
Ministry of the Interior, and the Asian Disaster Preparedness Center (ADPC). In thismeeting, Miyamoto outlined ICHARM and its activities related to flood and inundation forecasting and its possible contribution to the new Area-BCM project. He alsojoined the discussion about how this project should be carried out, based on the
progress in its preparation process on the Thai side, including the current status ofdata collection.
On October 11, Miyamoto and the others attended an Area-BCM workshop heldin Ayutthaya, which was co-hosted by Japan’s Ministry of Economy, Trade and Industry with other organizations. Discussing issues about the 2011 flood, he learned
what kind of information corporations were hoping to have in the middle of thedisaster and what kind of information should be offered to produce effective
Area-BCM. On October 12, they paid a courtesy call on the director general of the
Department of Disaster Prevention and Mitigation (DDPM) of the Ministry of theInterior. After that, they had a meeting with officials of the departments in chargeof the new project and collected information about industrial complexes besides
Rojana Industrial Park. The meeting was a good preparation for starting up the new
project.

Training on discharge observation and riverbed topography measurement
ICHARM has been involved in a UNESCO Pakistan project, “Strategic Strengtheningof Flood Warning and Management Capacity,” since 2012. In phase I of this project,
ICHARM assisted local experts in developing a localized flood inundation forecasting system using the Integrated Analysis System (IFAS) and the Rainfall-RunoffInundation (RRI) model. Phase II started in 2015, aiming to equip the developed
system with the capabilities of estimate flow discharge and riverbed topography sothat the system works with better forecasting accuracy. To this end, ICHARM provided river discharge observation equipment for the Pakistan Council of Researchin Water Resources (PCRWR). ICHARM also offered training for local engineers tolearn how to use the devices.

A team of researchers from ICHARM and PWRI conducted a field survey in theWest Rapti River in Western Nepal. The survey was carried out from October 31
through November 5, 2017, to characterize the longitudinal grading of the river
based on the grain size of riverbed materials. As sediment production is high in theupper reach and no dams have been built in the river, the sediment produced istransported downstream to the middle and lower reaches. For this reason, the target river offers significant survey points to observe the longitudinal grading phenomenon.
The survey team used a rubber boat, moving downstream in the 25-kilometer section of the river running in Nepalgunj and confirmed changes in the distribution ofriverbed materials while taking photos for the area grid method and sampling fine24

results of this survey provide valuable
information to understand the phenomena of the topography, flow and sedimenttransport in the mountain area. We willcontinue in-depth analysis for better understanding of those phenomena.

Field Survey in the Sittaung River of Myanmar to Investigate Riverbank and Coastal
ErosionThe downstream of the Sittaung River in Myanmar consists of complex and dynamic system of shoals and braided channels. Morphology of the estuary changes
actively owing to river flow and tidal motion including tidal bore. Severe riverbank
and coastal erosion around the mouth of the Sittaung River has been a pressing issue in Myanmar. Since 2014 erosion at the west side has caused substantial loss ofagriculture land.

Under the background, in May 2017, the government of Myanmar requested ICHARM to plan erosion control measures. After discussing how it should respond to
this request, ICHARM decided to conduct a joint field survey with the University ofTokyo, which has been involved in other research projects in Myanmar, to investigate and understand the current situation of erosion-related issues. The survey
was conducted on October 29 and 30, 2017, assisted by the Directorate of Water
Resources and Improvement of River Systems (DWIR). From ICHARM, Research andTraining Advisor Shinji Egashira, Deputy Director Hisaya Sawano, Senior Researcher
Badri Shrestha, and Research Specialist Young-Joo Kwak joined this survey.
Before the field survey at the selected sites, the preliminary image analysis was applied to severe coastal change region using ALOS-2 and Landsat-8 satellite data
between 2007 and 2017 processed by Dr. Kwak. For example, Figure 1 shows thatthe maximum lateral erosion distance on the right bank is over 2 km despite one
year.
During these two days survey, the team collected sediment materials from the riverbed and the bank for analysis of grain size distribution and sediment properties.
The Arial photos and videos were also captured the representative eroded areas(H marks in Figure 1) using Drone (MAVIC pro, DJI) to investigate river bank ero25

The team also measured river water level which seems to be affectedby tidal level by installing water pressure senor at the River in Su Pa Nu Village forthese two days. The water depth along the boat route during the field investigation
were also measured using fish detector (fish sonar).
Based on the findings of this primary study, additional investigations and data thatwill be required for detailed planning of the feasible measures for riverbank andcoastal erosion control will be proposed.
