Message from Executive Director
Snowy regions are ‘lightful’ and wet air masses are lighter
Many say that snowy regions are dark, butobservations using an illuminometer tellus otherwise. In winter, the cloud-filled
sky over a snowy region is actually more‘lightful’ by 10 percent than the cloudfree sky in a snow-free region. True, lesssolar energy arrives at the land surface insnowy regions because of clouds. However,almost all energy that reaches the groundis reflected upward on the land surface and Keynote Lecture at the Symposium on River & Basin

the brightness in snowy regions. In otherwords, a bright snowy region is a quality
luminous environment created by indirect lightning from the “natural reflective ceiling and floor.”
Next, let’s take a look at clouds. As you know, clouds consist of 10 to 100 μm water
droplets, into which water vapor condenses as it ascends from the ground to the sky.
Then, don’t you wonder why wet air masses, which seem heavier than the air, cankeep themselves floating in the sky?
The gas law tells us the secret. It says that the same number of molecules are included in a certain volume at a certain temperature and pressure regardless of gas type.
Dry air is a mixture gas of oxygen and nitrogen at a ratio of four to one. The average weight of an air molecule is 28.8 because the weights of oxygen and nitrogenmolecules are 32 and 28, respectively, while a water molecule weighs 18. Let’s consider an air mass with five molecules in a certain volume at a certain temperatureand pressure. The weight of a perfectly dry air mass is 28.8×5=144. A wet air masscan be expressed by replacing dry air molecules with the same number of watermolecules. If one dry air molecule is replaced with one water molecule, the weightis 28.8×4+18×1=132.2. If two, 28.8×3+18×2=122.4. This means that the air mass
becomes lighter as it becomes wetter.
If we are willing to observe and understand water’s mystique, we will be able to see
an amazing world existing right before us. And as the two examples show, sciencecan be a big help. Let’s enjoy exploring the world of water through science.

雪国は明るく、湿った空気は軽い
雪国は暗いと言われます。しかし冬に、一面雲で覆われた雪国の空と、
雪のない地域の晴天日の空を照度計で測って比較しますと、雪国のほうが１割程度明るいのです。雪国では雲が広がりやすいために地表に届く
太陽光は減りますが、届いた光のほ
とんどが雪面で反射され、それがまた雲の底面で反射され、光が多重に反射しあう光環境ができるからということが分かりました。つまり雪国
は、壁や天井、床を間接光で明るくした良好な光環境ということができます。
その雲は、地表付近の湿った空気が上昇して、上空で凝結して 10 ～100 ミクロンメートルの水滴になったものです。ところで、湿った空気は重いはずなのになぜ上空に昇っていくのか、不思議に思われませんか？
気体はその種類に拠らず、一定の
気温、気圧であれば、一定の体積に含まれる気体分子の数は気体の種類によらず、同じという法則があります。乾いた空気は酸素と窒素が１対４の割合で混ざった気体で、酸素の重さは 32、窒素の重さは 28 ですから、
乾いた空気分子の重さは 28.8 となります。一方水は水素２個と酸素１個が結合したものですので水分子の重さは 18 になります。ある容器に５個の気体分子があったと考えましょう。 完 全 な 乾 燥 空 気 の 場 合 の 重 さは 28.8 × 5=144 と な り ま す。 こ れを気温、気圧を変えずに少し湿った
空気にします。つまり 5 個の乾燥空気分子の１つを水分子に置き換えます。そうすると乾燥空気分子４、水
分子１となり、重さは 28.8 × 4+18
× 1=132.2 となります。さらに湿った場合を考え、乾燥空気分子 3、水分 子 2 と し ま す と、 重 さ は 28.8 ×
3+18 × 2=122.4 と な り ま す。 こ のように、空気は湿れば湿るほど軽くなるのです。
水の神秘性を素直に観ずることができれば、違った世界が広がるかもしれません。科学を通して、水の不思議を楽しんでみませんか。

The 9th International Conference on Flood Management (ICFM9)
第 9 回洪水管理国際会議（ICFM9）開催のお知らせ
The International Conference on Flood Management(ICFM) is held every three years to discuss a wide rangeof flood-related issues and achieve significant academic
and cross-disciplinary changes. The conference is an active
forum for engineers, planners, natural and social scientists,
health professionals, disaster managers, decision-makers, policymakers, and otherresearchers and practitioners to come together from around the world and share thelatest findings, information, and experiences. It has been an excellent opportunity
for people involved in flood management to learn the current status of water infrastructure systems in each country, get to know fellow experts in other countries, andactively participate in the co-creation of wisdom. Holding an ICFM in Japan will be
the first time in 12 years since ICFM5 took place in Tokyo in 2011.
Under its grand theme, “River Basin Disaster Resilience and Sustainability by All:
Integrated Flood Management in the Post-Corona Era,” ICFM9 plans presentations and discussions on important issues to be addressed in the post-corona era,
including how to rebuild a flood-sensitive society and how to shift the current flood
management to comprehensive and multi-layered water-related disaster risk reduction that combines hard and soft measures and takes climate change into account.

The Project for Development of a Hybrid Water-Related Disaster Risk Assessment
Technology for Sustainable Local Economic Development Policy under Climate
Change in the Republic of the Philippines (HyDEPP-SATREPS) is a joint research project between Japan and the Philippines under the Science and Technology ResearchPartnership for Sustainable Development (SATREPS). Since the kick-off of the project in June 2021, ICHARM and collaborative institutions, both in Japan and thePhilippines, have been conducting various activities.
On November 16, 2022, the 3rd
Joint Coordinating Committee(JCC) was held in Quezon
City, Metro Manila, with representatives from researchorganizations of the two countries. The JCC has so far met
every six months. However,since the kick-off and the 1st

and 2nd JCC meetings were
写真１ マニラでの第 3 回合同調整の集合写真
held online due to travel restrictions under the COVID-19 pandemic, the 3rd JCC was the first face-to-face meeting
since the project started. Japanese research members visited the Philippines for the
first time in three years since September 2019. At the JCC, each research groupreported on the progress of their assignments. For example, one group explainedthat the flood monitoring system using the RRI model in operation in the PampangaRiver basin in the northern part of Metro Manila successfully detected the flooding
caused by Typhoon Karding in September 2022. Before and after the meeting, theJapanese members also visited four cooperating government organizations and had
fruitful face-to-face discussions.
From
November27
toDecember 10, 2022, 14 project
members from the Philippines
were invited to Japan as part oftraining on flood risk assessmentand management technology.
During the first week, theyattended meetings at ICHARM,
where the Japanese members
explained the technologies

The invited members also took field trips to the Kinugawa River, the Tsurumi River,and other relevant sites. Since the western shore of Lake Laguna, a project site, hasbeen rapidly urbanized in recent years, the Filipino members showed great interest particularly in flood risk management technologies implemented in the Tsurumi
River basin as potential measures to cope with the urbanization.
In the second week, the Filipino project team moved to the Kyoto and Shiga area to
see flood management in Lake Biwa and its tributaries, including the Lake Biwa Canal.
They also met the Japanese project members of the University of Shiga Prefecture,

UPLB’s IdSCW First International Conference on Interdisciplinary Water Studies
The University of the Philippines Los Baños (UPLB) Interdisciplinary Studies Center for Water (IdSCW), which conducts
a collaborative 5-year SATREPS project with ICHARM, held the first International Conference on Interdisciplinary Water
Studies termed “iWatCon 2022” on November 10 and 11, 2022, under the theme of “REIMAGINING WATER FUTURE:
Connecting the Visible and Invisible.” This 2-day online conference was attended by more than 120 participants, with
Executive Director of ICHARM KOIKE Toshio as the keynote speaker.

Figure 1 iWatCon 2022 Online

In his keynote address, the executive director discussed the water
cycle consilience, a concept highly relevant to the conference
theme. It is about the integration of observations and models andstresses that the key to understanding the mechanism and relationship between phenomena occurring at different places andtime is data integration and analysis, after which the results should
be shared among communities worldwide. This translates to an
output of science that should be used in making evidence-based
decisions. He cited some examples of a water cycle consilience
framework that can connect the visible and the invisible: for
instance, groundwater variation using satellite data; the coupled Figure2: Executive Director Koike delivering his keynote address at
iWatCon 2022 participants
data assimilation of a land surface model and a dynamic vegetation model; and the three-month prediction in the seasonal production of wheat in Morocco, Algeria, and Tunisia.
This water cycle consilience as a framework may lead the participants and organizers of its advocacy to take conscioustransformative steps in having sustainable projects and programs that will be very useful in achieving evidence-based
policies and decisions.

ICHARM published a booklet entitled “Collection of Critical Situations during
Flood Emergency Response” on its homepage in June 2020, aiming to improve theemergency response capacities of local governments and promote more effective
management of flood disasters. Defining critical situations as ones in which local
government officers panic, do not know what to do, cannot make a decision, areconfused, struggle in dilemma, etc., during an emergency response effort, this collection introduces typical critical situations from the review reports of past flood
disasters. (https://www.pwri.go.jp/icharm/special_topic/20200625_flood_response_collection_e.html).

Introduction of ICHARM research projects / 研究紹介
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

主任研究員

I have been working with ICHARM since 2015, and my activities at ICHARM are aligned with ICHARM’s three pillars(i.e., research, education and capacity building, and information networking). My research is in the field of waterand sustainability in a changing climate. Hence, my major research contributions have been achieved in the field ofsatellite rainfall estimation, ensemble flow forecasting, and climate change impact assessment, as well as the development of an advanced hydrological model for seamless modeling to address various water-related issues (i.e., flood,
drought, and water availability) under a changing climate. Presently, I am working on the development of a system
for the integrated management of water resources and disasters in line with the mid- to long-term plan of ICHARM(2022-2027) (i.e., developing a highly reliable technology) by integrating multi-platform data, various state-of-theart models, and other technologies (Fig. 1) to support and implement the three major global agendas (i.e., Sendai
Framework on Disaster Risk Reduction, Paris Agreement on Climate Change, and Sustainable Development Goals) byobtaining evidence-based information for the effective management of water resources and water-related disasters
under a changing climate in poorly gauged basins around the world.
As shown in Fig. 1, the system for the integrated management of water resources and disasters is based on the following two major ongoing research activities at ICHARM:
1. Generating reliable distributed rainfall data in poorly gauged basins:
Real-time or near-real-time rainfall data with high spatial and temporal resolutions are a prerequisite for effective
water and disaster management. However, since they are rarely available for most river basins, freely-available global
satellite precipitation products (SPPs) are alternatively used thanks to recent technological advancement. ICHARM
has continuously collaborated with JAXA to maximize near-real-time SPPs for effective water resources managementin poorly gauged basins. As SPPs are subjected to various errors, information from ground gauges is incorporated to
improve the quality of SPPs in hydrological applications. ICHARM has investigated and proposed a network design
method for finding a threshold and configurations necessary for effective bias correction of SPPs and flood infrastructure investment (Zhou et al., 2022). A rainfall climatology map derived from SPPs can also alternatively be used
for finding the gauge threshold and its configurations to guide smart investment in poorly gauged basins in order toestablish rainfall observation infrastructure and merge real-time ground data with real-time SPPs to produce superior
rainfall products for the effective basin-wide management of water resources and water-related disasters.
2. Development and application of a hydrology and crop/vegetation coupled model:
Distributed Hydrological Models (DHMs) with the capability of simulating catchment-scale water and energy budgets

and rainfall-runoff-inundation processes are essential tools for the Integrated Water Resource Management (IWRM)
and Water-related Disaster Risk Reduction (WDRR) under a changing climate. ICHARM’s RRI model mainly considers
the conservation of water balance and ignores several important physical processes, which can be sources of uncertainties. ICHARM has developed the Water and Energy Budget-based RRI (WEB-RRI) model to improve interception,
evapotranspiration (ET), infiltration, runoff, and inundation processes, thereby improving the accuracy of low-flow
estimation, flood onset timing, peak flood discharge, and inundation characteristics (Rasmy et al., 2019). Notably, it
is compatible with various input variables produced from multiple data sources such as satellites, re-analyses, in-situ
data, and GCM projections for long-term seamless simulations of past and future climates. The model has been
applied to several projects led by ICHARM/PWRI, such as flood forecasting and climate change impact assessments,
in different parts of the world. To expand the model applicability and simulate vegetation growth and crop yield, the
WEB-RRI model was coupled with the dynamic vegetation model (Sawada and Koike, 2014) and the Simulation of
Weather Rice – SIMRIW (Homma et al., 2017). The applicability of the coupled model is currently under verificationin the Pampanga River basin of the Philippines and the Solo River basin of Indonesia. By applying the coupled modelwith various forcing data (e.g., real-time and long-term predictions and climate projection data), the system cangenerate very useful socio-economic information for different purposes (e.g., hazard maps, disaster early warning,assessment of risk and damage, review of irrigation practices, evaluation of adaptation measures, and assessment of
impacts on the economy) to support and implement the three major global agendas.

Educational program updates
研修活動報告Since 2007, ICHARM, in cooperation with the Japan International Cooperation
Agency (JICA) and the National Graduate Institute for Policy Studies (GRIPS), hasprovided a master’s program, “Water-related Disaster Management Course, Disaster
Management Policy Program (JICA Knowledge CO-Creation Program on “Flood
Disaster Risk Reduction),” mainly designed for foreign government officers to obtaina degree in one year. The students learned theories and practices in the first halffrom October to March and work on their theses in the second half from April toAugust. The program started its 16th year, welcoming 13 new students on September
30, 2022.
●Opening ceremony

On September 30, the 16th opening ceremony of the master’s course for the academic year 2022 was held at the ICHARM auditorium. Deputy Director General of
JICA Tsukuba SHIBATA Kazunao, GRIPS Professor SUGAHARA Masaru, PWRI President
FUJITA Koichi, and other executives attended the ceremony and gave a warm welcome speech to the students. Ms. RANAPURA DEWAGE of Sri Lanka also deliveredan address on behalf of the students.
●Lectures<Special lectures >ICHARM occasionally invites experts in water-related
fields and holds special lecture sessions for master’sand doctoral students and ICHARM researchers to
update themselves with the latest knowledge andfindings and deepen their insights and understanding
in their research areas.

On October 4, ICHARM invited Dr. Zhongbo Su, a proSpecial lecture by Prof. Su
fessor at the University of Twente in the Netherlands,

to give a special lecture. He is one of the world’s foremost experts on remote sensing and modeling of hydrological processes and climate
data and information. It was an extremely valuable opportunity for newly enrolled
master’s students to start their one-year program.
On the same day, Professor Emeritus of the University
of Yamanashi TAKEUCHI Kuniyoshi also gave a special
lecture on NINOMIYA Sontoku, Japan’s famous social
reformer in the 19th century. He restored many towns
and villages devastated by floods and famines using
his extensive agricultural knowledge, civil engineering
talent, and unique administrative skills. The students
learned how the spirit of Sontoku has been inherited
in ICHARM’s mission of “Localism and Empowerment.”

視察後に、学生は自国の状況と比較しながら今回の視察で学んだことをレポートとして提出しました。その一部を以下、掲載します。
【学生からの声】■ パキスタンの場合、洪水警報局は設置されているが、その数は限られており、すべての河川をカバーしているわけではない。特に丘陵地の急流は、今年のように大きな鉄砲水が発生することがある。また、新しいコン
セプトである霞堤がないため、帰国後、関係当局に霞堤の設置を提案する予定である。
（パキスタン修士学生）■ フィリピンのような発展途上国では、非構造的な対策と構造的な対策を統合したアプローチを採用する必要がある。問題は、フィリピンが災害軽減よりも災害対応に重点を置いていることである。予測や早期警報といった非構造的な活動だけでは不十分で、堤防やダムといった構造的な減災のための構造物の支援が必要であり、この 2 つを組み合わせることが、洪水の影響を軽減する最も効果的な方法であると考えられる。日本はその最たる例を採用していると言える。
（フィ
リピン修士学生）■ 現在、スリランカは頻繁に洪水に見舞われる傾向にある。そのため、日本で行われている洪水管理手法の多くは、スリランカでも有効に活用することができる。また、自然の保水・遊水機能の保全を含む総合的な洪水管理の推進は、スリランカにとって重要である。しかし、現在の経済状況を考えると、ポンプ場や砂防ダムの建設は非常に高価な洪水管理技術である。さらに、スリランカのいくつかの河川流域では水文データの測定と収集が包括的でない。したがって、一連の水位観測所を適切に維持している
日本のやり方は、スリランカが未測量の河川流域に独自のテレメータ付き河川計測ネットワークを設計する上で実に良い例となる。

●Field trip

A ceremony of the Best
Presentation Award

Best Presentation Award 授賞式<Watarase and Kinu River basins>

On October 19-21, the master’s students took a three-day field trip and visited the
Watarase and Kinu River basins, accompanied by officers of the Kanto Regional
Development Bureau of the Ministry of Land, Infrastructure, Transport and Tourism
and HARADA Daisuke, a research specialist of ICHARM. At the Watarase River basin,
they listened to an officer explaining the basin’s history, including the economic
development of Japan, which was closely related to the copper mining at the Ashio
Copper Mine, located near the river, and the resulting environmental destruction. At
the Kinu River basin, they learned about the construction of open and continuous
levees, flood control measures, the history of water resources development andpower generation, including dams, and the levee breach and flood inundation in2015.

After the visit, students submitted a report on what they learned during the field trip,
comparing the various measures they saw with the situation in their countries. The
following are parts of their reports.

【Comments from students】■ Student from Pakistan: In the case of Pakistan, we
have installed flood warning stations, but these are limited and not covering all streams. Especially hill torrents
are ungauged, causing huge flash floods like this year.
We do not have open-type levees, which are a new concept, and I will propose some open-type levees at somelocations in Pakistan to the concerned authorities upon
my return.
■ Student from the Philippines: In developing countries
like the Philippines, an integrated approach using bothnon-structural and structural measures must be adopted. The problem is that the country focuses on disaster
response rather than mitigation. It can only do so many
non-structural activities like forecasting and early warning, but we all know that it isn’t enough because there isa need for the support of structural mitigating measures
like levees and dams. A mixture of these two is seen to be
the most effective way of mitigating the impacts offloods, and Japan caters the best example for that.

Students listening to an explanation

Prevention Station

At Kawaji damu
川治ダムにて■ Student from Sri Lanka: Currently, Sri Lanka is prone to frequent flooding. Thus,
most of the flood management methods practiced in Japan can be effectively used in
Sri Lanka. The promotion of integrated flood management, which includes the preservation of the natural retention and retarding functions, is really important for Sri
Lanka. However, considering the current economic condition of the country, the construction of pumping stations and sabo dams are really expensive flood management
techniques for Sri Lanka. The hydrological data measurement and collection are notcomprehensive in some river basins in Sri Lanka. Therefore, Japan’s practice of maintaining a proper series of water level measuring stations is a really good example for
Sri Lanka to design its own telemetered river gauging network for ungauged river
basins.
Finally, ICHARM would like to express the deepest gratitude to all the staff andofficials who cooperated on this field trip.

Supervisor: USHIYAMA Tomoki

My name is Jayasekara Sachintha from Sri Lanka. I have been working as a Meteorologist in the
Department of Meteorology in Sri Lanka. I have obtained my first master’s degree in Applied Statistics
from the University of Peradeniya, Sri Lanka and I completed my second master’s in Environmental Sciences in
the University of Tsukuba, Japan. I am currently pursuing my PhD degree in Disaster Management at GRIPS.
I am interested in extreme weather forecasting, and hope to focus my study on improving the extreme weather forecasting in pre-monsoon and post-monsoon seasons in Sri Lanka. Thus, I am glad to have this opportunity to study and work with experts in water-related hazard and disaster management. This will be a perfectopportunity for me to enhance my knowledge and skills and contribute to the betterment of my department
and country.

Hote Hassan Haren

Supervisor: KOIKE Toshio

I am an employee of the Government of Pakistan and belong to the Pakistan Administrative Service,
which enables me to work across the country in different roles. I hold a Master of Governance andPublic Policy degree from the University of Queensland, Australia under the Australia Awards scholarship programme. After having worked in flood disaster situations across different regions of the country, I developed
an interest in addressing policy and governance related issues of the disaster management paradigm. The
focus of my research is to explore avenues for improving flood disaster risk governance in Pakistan. Today’s
literature tells us that disasters result due to human actions or inaction because hazards by themselves do
not cause disasters, as it is the vulnerability of a society that exposes it to a hazard situation, which in turn results into a disaster. My aim is to find ways for making Disaster Risk Reduction (DRR) a continuous process ofthe disaster management system in Pakistan, by addressing cross-sectoral and multi-disciplinary aspects forachieving integrated management of flood related risk.
I am thankful to JICA, GRIPS, PWRI and ICHARM for allowing me this opportunity to work for the bettermentof my country.

Supervisor: KOIKE Toshio

I am Subash Tuladhar, a Senior Divisional Hydrologist at Department of Hydrology and Meteorology
under Ministry of Energy, Water Resources and Irrigation in Nepal. I have been working with Snow
Survey and Glacial Lake Section in my organization. I have completed MSc in Water Resources Engineeringfrom Tribhuvan University, Nepal in 2009.
It is great opportunity for me to join the PhD course in Disaster Management at GRIPS and to carry out research work in ICHARM. My research interest is to study on impact of climate change on water resources ofmountainous catchments with frozen water (snow, glacier and permafrost) and to understand the basin hydrology of mountainous catchments of Nepal by assessing the contribution of snow and glacier-melt in river
runoff. I intend to utilize the knowledge gained from the course to serving the wider society and my country.

My sincerest thanks and gratitude to DPWH for their trust in nominating me for this course; to JICA, ICHARM – PWRI
and GRIPS for giving me this rare opportunity to become one of the scholars for this Masters Course and to learnmuch about Flood Disaster Risk Management. I am looking forward in acquiring all knowledge and skills, in givingback to my country in addressing our problems in flooding and in fostering closer ties between my country andJapan.
Mabuhay! I am John Paul Luching Lusabia from the Philippines. I work as a Local Disaster Risk Reduction
Management Officer (LDRRMO) in the Municipality of Mambusao, Capiz. I think the biggest challenge inthe practice of Disaster Risk Reduction Management in the Philippines is the ability penetrate consciousness and turn knowledge into behaviors. As a LDRRM Officer, who focuses on the four thematic areas ofdisaster management i.e., Prevention and Mitigation, Preparedness, Response and Recovery and Rehabilitation, it is
my duty to ensure that DRRM will not remain a concept but rather a lifestyle for ALL. By so doing, DRRM becomesa positive value and a conscious behavior geared towards building a resilient and sustainable community. For whatis structural and non-structural measures in managing disaster risks without the right values and sensible behaviors.
This is what sets the Japanese apart from any other and I am learning it first-hand here in Japan.
I am truly honored of this once in a lifetime opportunity and I am hoping to be able to bring something, if not all,back to the Philippines when this learning journey ends. Thank you so much, JICA. Arigato Gozaimasu, PWRI and
ICHARM. Maraming Salamat po, GRIPS.

I am Allen B. Orogo, from the Philippines. I am a Hydrologist working at the Philippine Atmospheric,Geophysical and Astronomical Services Administration. I majored in Physics in my bachelor at Ateneo deNaga University. Fundamentally, my task is to provide hydrological forecast for the entire Bicol River Basinincluding daily hydrological forecast, Flood Advisories and Flood bulletins. These are used as guides by ourDisaster management officers for decision-making during the occurrence of flood-related hazards.

The first time I have heard of pursuing Master’s degree in ICHARM was in 2017 when I participated in a capacity
development for flood risk management in the same institution. My enthusiasm was stirred as I envisioned meaningful professional experiences ICHARM is offering. Soon enough I was accepted as a Master’s Student in Flood
Disaster Risk Reduction for the year 2022-2023. It has been a great privilege being endowed with scholarly education through series of lectures, research activities and field trips. I will forever be indebted to JICA and ICHARM forgiving me such an opportunity for professional growth that I can use for the enhancement of my functions in giving
accurate and timely flood forecast for the Bicol River Basin community.

Senior Civil Engineer, Malaysia Public Work Department,
PWD (Jabatan Kerja Raya Malaysia)

Being one of the Civil Engineer in Malaysia Public Work Department (PWD) who graduated from a
Flood Risk Reduction Master (Disaster Management) program offered by JICA, GRIPS and ICHARM
was such a great pleasure and opportunity for me. Although it was during the pandemic Covid19 and the 1st year of quarantine period, it is still such a great experienced and exposure to me. I
was also blessed to receive the study leave permission from the Public Service Department (Jabatan
Perkhidmatan Awam, JPA) and Public Work Department, PWD on joining the Master program.

To start with, I joined PWD in early 2005, three years
after I graduated a degree from the local university.
Being in service with the government sector for 17
years, brings me to a numbered of experience where
the human resources (HR) strategic in PWD was togive the officer a job rotation experienced. I was with
Building and Facilities Maintenance Branch for 6 years
from 2014-2020, it’s one of the 24 branches in PWD.
My experienced was to performed condition assessment which called Building Condition Assessment(BCA) to government buildings by assessing the
A Building Condition Assessment (BCA) activity at one of the schools involvedin the flood
defects present, determining the risks if the structureis left in its original condition with or without maintenance work and finding out the maintenance work that need
to be done to preserve the building in its working condition. I brought my experienced on how PWD did the BCA
into my thesis writing during the master program. In which, it became a starter for the BCA to become a tool toassessed building condition after the flood occurred and it was used for the assessment after the flood event inNovember- December 2021. Currently BCA has become the important tool for PWD and Malaysian Government
on managing the asset in both pre and post disaster.

Besides that, right after graduating and returned to Malaysia, I was placed in the Competency Development andExamination Unit. It is one of the Unit in the Policy, and Corporate Management Branch, PWD. Blessing with thegrade promotion during the study, my return to fill in the placement was somehow, a challenge and an opportunity for me. My task is to oversee the opportunity on the in-service training for all the officers in PWD, initiatinga collaborative works with the local Universities on enhancing the officer’s competency and development, and to
upgrade the competency model that used by PWD since 2014. Getting myself placed in the branch is out my control, but what I have learned while I was in Japan and from master program is that I could use the experienced toestablish something. Favorably, a medium to interact with all the government agencies and universities to initiate
any works and collaborative study especially on the disaster management and policy program that involved with
PWD. These also a medium for me to identify the gap about disaster knowledge among the officers in PWD andthen bridge them together with the collaboration among agencies that connected with the gap.
As the civil service in Malaysia must interact effectively with the private sector, PWD’s officers need to initiate
and be the catalyst for the private sector, transforming it to become more proactive rather than reactive. Prior to17

this, one of the activities that I am involved was organizing a Master on Disaster Risk Management program with
Malaysia-Japan International Institute of Technology (MJIIT). PWD, previously had identified about 20 numbers ofofficers with a multi-disciplinary technical background to joined in the program.

This program was a structured program
tailored with the PWD where, the syllabus was agreed to be custom-made withthe scope of work in PWD. As PWD is
one of the key agencies involved in mitigating and disasters especially on thefederal roads and slope management,
PWD need more effort to establish theirrole and responsibility when it comesto the disaster mitigation and risk
reduction. One of the objectives of this PWD’s officers involved in the collaborative program and studies with MJIIT on Disaster Risk
program was to incorporate the disserManagement
tation study with the current situation in
PWD on implementing the mitigation and risk reduction. The findings and output of the thesis or dissertation isused to propose to the PWD’s top management on way forward for the PWD to emphasize, engage, and undertake the responsibilities to become the relevant to in control with the responsibilities on disaster mitigation andreduction. Besides that, PWD and MJIIT is also collaborating in other activities related to disaster. One of the
programs is the National Slope Plan that schedule to be enhance sooner in 2023.

Vincent and the Grenadines, Timor-Leste, and Bangladesh. They first received a lecture on flood forecasting and hands-on training on how to use theRainfall-Runoff-Inundation (RRI) model. Then, they practiced operating the RRI
model on their personal computers for a sample basin, creating basin models, calculating river discharge, and displaying results such as water depth and flood area. The
participants whose expertise is not river engineering also engaged actively in the
training, asking many questions, including ones about the RRI model and ICHARM’sefforts in flood forecasting. Some of the participants commented that they would
like to introduce the RRI model to flood forecasting in their countries, realizing its
high forecasting accuracy and operability through the training.

On this occasion, he delivered a presentation entitled “Global changes and theirimpacts on the hydrological cycle,” addressing current global issues in water scienceand the prospects for freshwater resources in the 21st century. Pointing out that
extreme floods, droughts, and other events have been more frequent in recent years,
with an example of 100-year floods occurring every 20 years in many parts of theworld, Professor Szollosi-Nagy concluded that the current infrastructure approach,which is based on the concept of “T-year design flood” developed using the stationary hydrological cycle hypothesis, is no longer effective. He then suggested theurgent need for new approaches and standards adjusting to the non-stationary
nature of the hydrological cycle. He also added that conventional structural measures should be reviewed regardless of their scales to cope with new challenges
and mentioned the construction of more infrastructure for floodwater storage, forexample.

Participation in the stakeholder consultation meeting and preparatory meeting of UN
2023 Water Conference
国連水会議のステークホルダー協議会合、準備会合に参画
The UN 2023 Water Conference, officially named the United Nations Conference on
the Midterm Comprehensive Review of the Implementation of the Objectives of theInternational Decade for Action, “Water for Sustainable Development,” 2018–2028,
will be held on March 22-24, 2023, at the United Nations Headquarters in New York.
It has been 46 years since the last UN Water Conference took place in March 1977
in Mar del Plata, Argentina. A preparatory meeting was convened for this long-overdue conference at the headquarters on October 24-25, and Mr. MORI Noriyuki, theDirector for Special Research, participated from ICHARM.
On October 24, a stakeholder consultation meeting was held in a round table format
with related organizations and groups to discuss actions to be included in the Water
Action Agenda. Based on the results, a preparatory meeting was held to discuss andfinalize the dialogue themes for the upcoming UN Water Conference.

Opening Address by Li Junhua/UNDESA・Under Secretary General@ UN Water Conference - Stakeholder Consultation Meeting
国連水会議・ステークホルダー協議会合（Li Junhua/UNDESA・Under Secretary General の開会挨拶）

Approximately 1,200 stakeholders participated in the stakeholder consultation
meeting. It was divided into five roundtables (Governance, Capacity Development,
Data and Information, Innovation, and Finance) for interventions and discussions.
Mr. MORI mainly participated in the roundtable on Capacity Development and madean intervention claiming as follows:- For resilience and sustainability against water-related disasters, it is important toincrease the understanding and collaboration of all stakeholders in river basins.
- However, each basin has its own uniqueness, facing different problems, nurturing
indigenous knowledge and experiences, and requiring site-specific solutions.
- Moreover, as water-related disasters impact the water-food-energy-nexus and thequality of life, including health, education, labor, and poverty, inter-sectoral cooperation and actions are essential.
- Thus, it is crucial to foster “Facilitators,” that is, catalytic beings capable of integrating and translating interdisciplinary scientific and indigenous knowledge for all
stakeholders to cooperate in building social consensus in their river basin.
Moreover, he proposed specific actions to develop a platform in each river basin
and use it to foster facilitators by explaining, for example, the “Online Synthesis
System for Sustainability and Resilience (OSS-SR),” which has been implemented in
the Philippines, Indonesia, Sri Lanka, and West Africa under the International Flood
Initiative (IFI).
Approximately 20 stakeholders made interventions at each round table, which werereported at the preparatory meeting on October 25 as the High-Level Summary of
Stakeholder Dialogue of the Preparatory Meeting for the UN 2023 Water Conference(https://www.un.org/pga/77/2022/10/25/high-level-summary-of-stakeholder-dialogue-of-the-preparatory-meeting-for-the-un-2023-water-conference/).

宮城県多賀城高校ご訪問
宮城県多賀城高校災害科学科の 1
年生 38 名と引率の先生方が、11 月
1 日と 2 日との２班で ICHARM を訪問され、職員からの講義や質疑応答を行いました。
この「災害科学科」は、2011 年の東日本大震災により未曾有の被害を受けた宮城県において、復興の重点として掲げられた災害教育の充実の一環として、大震災から学んだ教訓を確実に次世代に伝承するとともに、将来国内外で発生する災害から多くの命とくらしを守ることができる人材を育成するため、防災系の専門学科として設置されたものです。
講義では、ICHARM の概要紹介に始まり、中小河川水位予測システムの開発や気候変動将来ハザード予測、国際ネットワーク展開に関する話題、そしてフィリピンでの技術援助プロジェクトなど幅広い内容を紹介しました。
質疑応答では、「ICHARM が 行 っている取り組みの中で、今後の日本に最も必要とされることは何ですか。
」といった鋭い質問も出されるなど、生徒さんたちの意識の高さ、将来への希望を感じるとともに、我々職員も刺激を得た良い機会となりました。

Thirty-eight first-year students of the Disaster Science Department of Miyagi
Prefecture Tagajo High School and their teachers visited ICHARM in two groups on
November 1 and 2. ICHARM researchers welcomed the students, giving lectures andanswering questions.
The Disaster Science Department was established as a special department to enhancedisaster education, which was a priority of the reconstruction project started after
the Great East Japan Earthquake in 2011, from which Miyagi Prefecture sufferedunprecedented damage. The department aims to pass on the lessons learned fromthat catastrophe to the next generation and develop human resources who can contribute to mitigating damage in future natural disasters.
The lectures started with an overview of ICHARM, which was followed by others covering a wide range of topics, including developing a water level forecasting system
for small and medium-sized rivers, forecasting future hazards due to climate change,
promoting international networking, and conducting a technical assistance projectin the Philippines.
During the Q&A session, students asked sharp questions such as “What is the mostimportant thing that Japan needs in the future among the initiatives that ICHARM isdoing?” The event turned out also to be a good opportunity for ICHARM staff to feel
hopeful about the future and take a fresh look at their work.

Field Survey

Field Survey

A field survey in Thailand
タイにおける現地調査等の報告

Senior Researcher MIYAMOTO Mamoru and Exchange Researcher NUMATA Shingo
visited Thailand for five days, from October 24 to 28, 2022, for a field survey anda research meeting on the SATREPS*1 program in Thailand, “Regional resilienceenhancement through establishment of Area-BCM*2 at industry complexes inThailand (research representative: Professor WATANABE Kenji, Nagoya Institute ofTechnology).” This project aims to develop an Area-BCM tool for three industrial
parks in Ayutthaya Province to visualize the impact of disaster risks on the industry
by region and then build an operation system to utilize the tool for the industrial
parks and surrounding areas, thereby realizing a community that is resilient to disasters. ICHARM is in charge of building and analyzing flood inundation models andassessing risks in order to establish an Area-BCM.
During the field survey in Ayutthaya Province,
the two researchers investigated the shapesof water channels, water channel networks,
and the height of flood walls at multiple locations in the two industrial parks that had not
yet been surveyed. The water levels of the
Chao Phraya River and its waterways werehigh due to the heavy rainfall from August
to October, which caused flooding on a scalesecond only to the 2011 event that promptFlooding in farmland around an industrial park
ed the country to start this project. Therefore,
工業団地周辺の農地での浸水の様子
they also checked the effectiveness of thecurrent flood control that draws water from the Chao Phraya River through floodgates to farmland and observed the inundation of low-lying land. Flood inundation
models for the two industrial parks are already under development, and the resultsof this survey are expected to further improve the accuracy of the models.
In the research meeting, the ICHARM
researchers listened to Assistant Professor
Piyatida Ruangrassamee of Chulalongkorn
University explain the progress in the development of flood prediction for the Chao
Phraya River, another joint project of theirs
with the Hydro-Informatics Institute (HII) of
Thailand, and discussed calibration methMeeting at Chulalongkorn University
ods with the professor and other experts.
チュラロンコン大学での打ち合わせ
In relation to this, they also talked about aworkshop on the application of the RRI model scheduled at HII in May 2023, including cooperation in dispatching lecturers from ICHARM.
In addition, the day after the survey, the ICHARM researchers visited the Thai
Meteorological Department (TMD) to consult with them about the current flood
forecasting and warning system. Since TMD possesses multiple types of rainfall data,
including those collected using Doppler radars, they discussed future cooperation
between TMD and ICHARM in synthesizing and effectively utilizing such data forflood forecasting and warning.
In this project and others, ICHARM hopes to continue promoting new research andinitiatives with related organizations in Thailand.

さった皆さま、ありがとうございました。

Stay period: April 1 - December 2, 2022

I enjoyed eight months in ICHARM, finding an attractive
world of river sediment. In my previous view, rivers are culture, like a mirror reflecting people’s mind, thought, or philosophy. But now, I can see rivers as sediment flows. Rivers
flow on their own, even though there remain many unknown
topics; sorting, bank formation, and supply estimation. I
realized river engineers must chase them desperately. During
the internship, I studied 1-D river flow computation, whichgave me fundamental knowledge of sediment hydraulics and the difficulties oflive rivers. Thanks to Egashira-sensei, Harada-san, and Qin-san for great guidance and to everyone for the opportunity to take my first step toward understanding rivers.

Dr. Sebastian Lopez from Argentina (National University of Cordoba)

Stay period: September 6 - October 20, 2022

My name is Sebastian Lopez, I´m currently a Phd. Student at the National University of Cordoba, Argentina. Working
in the “Institute for advanced studies in engineering and technology” (IDIT-CONICET), the institution is one of theinstitutions participating in the Argentina SATREPS Project “PREVENIR”, as well as ICHARM. The main purpose of thisSATREPS project is to develop a flood alert early warning system for densely populated areas in Argentina, which will
couple meteorological forecast with flooding simulation in the target area. Hydrological simulation is needed, therefore
my main task during my seven weeks stay in ICHARM was to learn about RRI-Model, develop a model for Suquía river´s
Basin, calibrate and validate it.
During my stay, I was under the supervision of USHIYAMA-sensei, AIDA-sensei and KAKINUMA-sensei, which they very kindly give me all their knowledge and support for accomplishing the proposed goals, as well as letting meknow a lot about Japanese culture and cuisine (which I enjoyed it very much).
I developed the model for the target area and calibrate the parameters toachieve a good performance according to observed data. These results arevery important for the SATREPS project. We visited Kinugawa River´s dams
and let me learn a lot about how dams are operated in Japan. Finally, I
attended to hydrological lectures, that will enforce my Phd. Carrer.
I would like to thank Prof. MIYOSHI (Principal Researcher of SATREPS

Mr. Chamal Perera from Sri Lanka (Nagoya University)

Stay period: November 7 - November 21, 2022

My name is Chamal Perera and I am from Sri Lanka. I am a PhD student from the Nagoya University and my supervisor
is Dr. Shinichiro Nakamura.
I was very fortunate to do an internship at ICHARM during 7-21st November 2022 under the supervision of Dr.
TAMAKAWA Katsunori, Dr. Mohamed Rasmy and Dr. USHIYAMA Tomoki. During my internship, I learned to use Global
Climate Models (GCM) to analyze the future climate variability in the Kelani River Basin, Sri Lanka. The predicted highrainfall conditions from the GCMs were used to simulate a hydrological model (HEC-HMS) to identify the high flow
conditions in the study region. As per the analysis,
I was able to understand the possibility of occurrences of more frequent flood conditions by theend of the 21st century. The knowledge I acquired
during the internship is very important for theincorporation of climate change factors to my PhD
research.
I would like to thank ICHARM staff and all thestudents for their support and cooperation during
my stay at the ICHARM.

Editor's Note
編集後記

Thank you for reading the ICHARM Newsletter. I hope everything is going wellwith you all.
Here in Japan, we have had pretty cold weather but at the same time started
sensing that spring is approaching little by little, as the Mt. Tsukuba Plum Blossom
Festival is scheduled to begin on February 18 for about a month in the plumgrove of Mt. Tsukuba overlooking PWRI.
Things in our country are slowly returning to normal, although we are having the
8th wave of COVID-19. More Japanese have started going abroad, and more foreigners have started coming to Japan.
As mentioned in this issue of the newsletter, ICHARM will host the 9thInternational Conference on Flood Management (ICFM9) in Tsukuba City, Ibaraki
Prefecture, starting on February 19.
Back in August 2021, about a year and a half ago, at a special webinar held asa replacement for ICFM8, which was canceled due to the worldwide pandemic,
Executive Director KOIKE Toshio announced that ICHARM would host ICFM9 in
Tsukuba, Japan, in February 2023. Since then, all its staff has been working hard
for a successful event. We are now expecting nearly 400 participants.
Under the grand theme of “River Basin Disaster Resilience and Sustainability by
All: Integrated Flood Management in the Post-Corona Era,” ICFM9 will be an invaluable occasion for presentations and discussions on a broad range of flood-related issues, such as restructuring societies into highly flood-conscious ones.
We look forward to seeing you in Tsukuba when spring is just around the corner.
