Message from Executive Director
Resilience to Two Risks at Two Levels
Two years have passed since the
COVID-19 pandemic broke out.
Forced to respond to fearful impacts
by the unknown virus under scientific uncertainty, each nation has beenstrengthening medical examinations
and systems and transforming the society. These are literally ongoing efforts
to improve national resilience. At thesame time, the world has started realizing the urgent need to jointly establish
transnational resilience to cope with
attacks in waves by new variants andreduce vaccination coverage gaps
associated with income inequality.

Comparison among the outcome documents of three UN world conferences on
disaster risk reduction, “Yokohama Strategy and Plan of Action for a Safer World,”“Hyogo Framework for Action 2005-2015,” and “Sendai Framework for Disaster Risk
Reduction 2015-2030,” suggests that the emphasis on resilience became stronger with each meeting. The IPCC Fifth Assessment Report defines climate-resilient
pathways by combining mitigation and adaptation to realize the goal of sustainable
development. While acknowledging that national governments have the primary
responsibility for disaster risk reduction, the report particularly stresses that a joint
effort by the international community is imperative to fight climate change and promote sustainable development.
When UN Secretary-General A. Guterres addressed the 76th Session of the UN
General Assembly, he pointed out, “COVID and the climate crisis have exposed profound fragilities as societies and as a planet.” The world has come to recognize bothnational and transnational vulnerabilities. The recognition, however, is only possible
because of the global efforts that have been made incessantly. The world could not
identify these two levels of vulnerability and cooperate in developing a frameworkof what should be done without historical efforts to establish the political visionof sustainable development based on critical discussions about development andenvironment since 1972 and approving the SDGs in 2015. International response to
COVID-19 and climate change is the touchstone for improving resilience at the twolevels and achieving sustainable development.

新型コロナウイルス感染症（COVID-19）による災禍が勃発して2 年が経過しました。科学的不確実性の下で、感染拡大の衝撃に対して、国を挙げて検査・医療体制を構築・強化しつつ、社会の変容（トランスフォーメーション）による取り組みが続けられています。まさに実時間の国家のレジリエンス向上の挑戦と言えましょう。一方、各国のワクチン接種率に著しい所得格差が認められる中、新たな変異株の出現による波状的な脅威に対応するためには、国境を越え、世界が一体となってレジリエンス向上に取組む（トランス・ナショナル・レジリエンス）必要性
も肌身で感じるようになってきました。
これまで開催された 3 回の国連防災世界会議の成果文書、『横浜戦略(1994)』、『兵庫行動枠組 (2005)』、『仙台防災枠組 (2015)』を比較すると、回を追うごとにレジリエンスの向上が重視されてきた傾向を読み取ることができます。2014 年の IPCC の第5 次評価報告書では、持続可能な開発目標を実現するために緩和と適応を組み合わせて、開発のための気候
レジリエンスの道筋が定義されています。防災分野では一義的な責任は国家にあるとされているのに対し、気候変動や持続可能な開発の分野は国際社会が一体となって取り組むべき点が強調されています。
A. グテーレス国連事務総長は第76 回国連総会（2021 年 9 月）にて、「COVID-19 と 気 候 危 機 は、 社 会 として、そして地球としての深刻な脆弱性を露呈させました」と述べています。COVID-19 を通して、私たち
は、国家としての脆弱性と、国境を超えた一体としての世界の脆弱性を再認識することになりました。一方で、1972 年以来の環境と開発の関わりを踏まえて持続可能な開発の政
治理念を確立し、その実行目標を定めてきた歴史がなければ、これら二つのレベルでの脆弱性を認識し、その改善のための枠組はどうあるべきかについてすら考えが及ばなかったとも言えます。COVID-19 および気候変動への対応は、二つのレベルのレジリエンスの向上と、持続可能な開発目標達成のための試金石と言えましょう。

E-learning & Workshops for Strengthening Water-related Disaster Resilience andAchieving Sustainable Development under Climate Change by ALL

インドネシアに対する e ラーニング・ワークショップ「気候変動下における水災害レジリエンスと持続可能な開発」

ICHARM recently provided e-learning and workshops for Indonesian government officers working to solve issues related to climate change. The training program lasted fora month from October 5 to November 5, 2021, in the framework of “Strengthening
Water-related Disaster Resilience and Achieving Sustainable Development under
Climate Change by ALL.”As an activity of the International Flood Initiative (IFI), for which ICHARM has served
as the secretariat, Indonesia has organized the “Platform on Water Resilience andDisasters,” consisting of the Ministry of Public Works and Housing (PUPR), the National
Disaster Management Authority (BNPB), the Agency for Meteorology, Climatology, andGeophysics (BMKG), the Ministry of Environment and Forestry (KLHK), and the Ministryof Agriculture (KP). This e-learning opportunity was provided as part of this effort.
The aims of the e-learning and workshops were to provide capacity building training
for government officers and strengthen the collaboration among water-related ministries to help local stakeholders increase water-related disaster resilience and achievesustainable development under climate change. The participants were 35 government
officers from six ministries, i.e., the five ministries of the platform and the National
Institute of Aeronautics and Space (LAPAN).
The e-learning program had three courses: the participants learned about climatechange in course-1, government actions in course-2, and operation and management
in course-3. The lectures were produced and delivered through collaboration among
Japanese government agencies and other organizations, such as the Secretariat of
the Water Cycle Policy Headquarters of the Cabinet Secretariat, the Ministry of Land,
Infrastructure, Transports and Tourism (MLIT), the Japan Meteorological Agency (JMA),
the Japan Water Agency (JWA), the Japan Aerospace Exploration Agency (JAXA), Tohoku
University, and ICHARM. The e-learning program was designed for trainees to study
in their mother tongue as much as possible. The lecture materials were prepared withEnglish text and Indonesian audio for self-learning. Assignments were given in English,
but the participants were allowed to submit them in the local language. Also, three
joint workshops using a web conference tool were held between Japanese instructors
and local participants with Q&A and knowledge-sharing sessions using IndonesianJapanese simultaneous interpretation.
The opening session was held on October 5 with 70 participants by ministries and otherrelated agencies of the Japanese and Indonesian governments. At the session, H.E. Dr.
Basuki Hadimuljono, the minister of PUPR, delivered a video message to celebrate
the opening of the training event. Several representatives then delivered a speech,

ICHARM hosted the AWCI Session prior to the 14th AOGEO Symposium
第 14 回アジア・オセアニア地球観測に関する政府間会合（AOGEO）
アジア水循環イニシアティブ（AWCI）セッションの主催と AOGEO シンポジウム
The Asian Water Cycle Initiative (AWCI) Session was convened online on October 29,
2021, as a sectional meeting of the 14th Asia-Oceania Group on Earth Observations(AOGEO) Symposium. More than 50 people participated, including directors from
related organizations in the Philippines, Sri Lanka, and Indonesia. In this session,
among the activities of the IFI Platforms on Water Resilience and Disasters and
SATREPS, each country reported on the development of the Online Synthesis System
for Sustainability and Resilience (OSS-SR) and the implementation status and future
plan of the facilitator training, which were agreed on at the 13th AOGEO meeting.
Country reports related to the activities of the Platforms on Water Resilience andDisasters were presented by the representatives of the Philippines, Sri Lanka, andIndonesia. The representatives of the Philippines delivered a presentation on fostering
facilitators using an e-learning system in Davao and the activities of the project called
the “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)” and explained Typhoon Kompasu, which caused
the severe damage to the Philippines. From Sri Lanka, the representatives delivereda presentation on the background of the platform in Sri Lanka, the introduction ofan early warning system for the Mahaweli River, and plans for capacity developmentusing an e-learning system. From Indonesia, the representatives delivered a presentation on a recent project, “E-learning & Workshops for Strengthening Water-related
Disaster Resilience and Achieving Sustainable Development under Climate Change byALL” and explained the activities of their ministries for climate change adaptation inIndonesia.
In addition, three experts in respective fields spoke about cutting-edge researchand development: Prof. HOMMA Koki of Tohoku University on agriculture and food,climate change and water use, Associate Prof. YOSHIDA Takehito of the ResearchInstitute for Humanity and Nature of the University of Tokyo on ecosystem-based
disaster risk reduction, and Prof. KAWASAKI Akiyuki of the University of Tokyo on
floods and poverty.
Based on these discussions, AWCI’s implementation plan for 2022 and beyond was
discussed. The participants agreed to further integrate OSS-SR as a key knowledge
base in each Platform and accelerate fostering facilitators by making effective useof e-learning, and promote the Water Cycle Consilience in cooperation with various
socio benefit areas related to the Quality of Life (QoL), such as water-related disasterrisk reduction, urbanization, ecosystems, food, energy, poverty, health, education, andlabor.
The discussion results in the AWCI session were reported at the 14th AOGEO
Symposium (https://aogeo.net/2021-14th/), which was held online from November
10 to 12. The development of OSS-SR, the fostering of facilitators, and the promotionof the Water Cycle Consilience, all proposed in the AWCI session, were unanimously
agreed and successfully reflected in the final statement of the symposium.

ICHARM has been organizing R&D (Research and Development) Seminars on an
irregular basis to provide researchers with opportunities for self-development andupdating themselves with the latest research by inviting domestic and international
experts in the field of risk management and water-related issues.
The 67th R&D Seminar was held on
November 30, 2021, by inviting Dr.
YOSHINO Naoyuki, an emeritus professor of Keio University and theexecutive director of the Financial
Research Center, among other affiliations, as the speaker. In the lecture,
which was titled “Private Financing in
Infrastructure by Use of Spillover Tax
Revenues and Its Application to thePicture 1 A scene from the lecture

写真 1 ご講演の 1 コマ
YOSHINO explained “spillover tax revenues,” which are an increased tax revenue due to infrastructure investments andenhanced economic activities. He also highlighted the importance of appropriate
redistribution of spillover tax revenues to encourage the participation of the private
sector in infrastructure investment, with example cases from overseas. This concept
is highly in harmony with “River Basin Disaster Resilience and Sustainability by All,”
Japan’s new policy for water-related disaster risk reduction. It views a watershed as
an integrated space including the watershed and the floodplain area, and requires
national and local governments, private companies, residents, and water users totake concerted actions to promote disaster resilience and sustainability. The lecture
indicated that social systems should be organized in a way that the private sector
can benefit from investing in disaster reduction infrastructure, which plays a criticalrole in increasing social resilience to water-related disasters.
ICHARM has been making efforts to the promotion of this new policy by conducting
studies primarily on water-related hazards, such as flooding and climate change, andrisk management. The seminar, however, provided new perspectives and taught theimportance of considering the financial aspect in promoting and implementing sucha policy, which requires the participation of both public and private sectors.
ICHARM members are determined to widen the research perspective to further contribute to water-related disaster reduction. ICHARM will continue organizing
seminars at various opportunities in the future for further knowledge developmenton water-related issues from a wide range of perspectives.

Technology for Sustainable Local Economic Development Policy under Climate Change
in the Republic of the Philippines (HyDEPP‐SATREPS) is a 5‐year joint research project
between Japan and the Philippines under the Science and Technology ResearchPartnership for Sustainable Development (SATREPS). Since the kick-off of the projectin June 2021, ICHARM and collaborative institutions, both in Japan and the Philippines,
have been conducting various activities.
An open webinar titled “HyDEPP-SATREPS Research Project on Experience of Typhoon
Ulysses Disaster” was held on November 5, 2021, about a year after the typhoon hit
the Luzon Island of the Philippines on November 12, 2020, causing catastrophic
damage. This webinar was organized to mark one year after the disaster and shareresearch achievements related to the disaster. Therefore, the webinar was open to the
public, attended by a total of 243 people, including 186 non-project members.

In the webinar, researchers from bothcountries

reported in a series of situational reports published by the National Disaster Risk
Reduction and Management Council (Picture). The system was used to comprehensively compile the data and information on flood damage caused by Typhoon Ulysses.
Dr. Patricia Sanchez, the project manager at the University of Philippines Los Baños,
presented the preliminary results of the interview survey on the assessment of thedamage caused by the disaster. The webinar was successfully closed with a panel
discussion, where many questions and comments were made by the project members
and the public.
On November 17, 2021, two weeks after the webinar, an online Joint Coordination
Committee (JCC) meeting was held. The committee meets twice a year, gathering therepresentatives of the research organizations, collaborative institutions, and funding
agencies (JICA and JST). In the online meeting, the leader of each research subgroupreported their progress after the kick-off meeting in June. For example, one groupreported having integrated a hydrological model (WEB-RRI) and an agricultural crop
growth model (WIMRIW) and proceeding to model validation in the Pampanga Riverbasin, one of the target areas of the project. The meeting demonstrated that although
the situation had been difficult and on-site studies limited, ICHARM and collaborative
institutions in Japan and the Philippines were able to make good progress.

Before joining ICHARM, I worked under an assistant chief cabinet secretary ineconomic cooperation and infrastructure at the Cabinet Secretariat of Japan from
October 2018 to January 2021. I was assigned to coordinate projects to expand
Japan’s infrastructure systems overseas. In this article, I will explain Japan’s effortson this matter.
The government of Japan strives to expand the country’s quality infrastructure systems overseas for the following objectives:- The demand for infrastructure development around the world, especially in developing countries, is enormous, and further market expansion is expected in the future
due to rapid urbanization and economic growth. In these circumstances, the government aims to capture this robust worldwide demand by utilizing Japan’s technology
and know-how in infrastructure development, thereby also leading the country toachieve strong economic growth. These aims are consistent with Japan’s general
growth strategy and international business promotion strategy, which are designed
to stimulate private investment and attain sustainable growth.
- The government of Japan has adopted the SDGs Implementation Guidelines (partially revised on December 20, 2019) and has been promoting efforts to establish
its own models to achieve the SDGs, including the realization of Society 5.0 byimplementing high-quality infrastructure. The government plans to maximize thisexperience and support overseas countries in solving social issues and achieving theSDGs by continuously providing high-quality infrastructure tailored to their needs.
However, for Japanese companies to participate in overseas infrastructure projects, they must have technological capabilities and win global price competitions.
Infrastructure projects generally have a long project period and involve many stakeholders such as the companies, government agencies, and local governments of thepartner country. Risks include those related to business (e.g., demand estimation,
toll collection, land expropriation, environmental and social considerations), foreignexchange, system changes (e.g., ones regarding the Public Private Partnership), andcontract breaches committed by governments. In some cases, private companies

are forced to bear the risks that the partner government is supposed to bear. Many
issues are often too complex for the private sector to solve by themselves. Thus, thepublic and private sectors need to work together, for example, by getting involved inprojects from the early stages and improving the investment environment.
For these reasons, the Ministerial Meeting on Strategy for Infrastructure Export andEconomic Cooperation (chair: Chief Cabinet Secretary) has formulated strategies forexporting infrastructure systems overseas to strengthen concerted efforts involving
various public and private organizations, such as government ministries and agencies,
the Japan International Cooperation Agency (JICA), the Japan Bank for International
Cooperation (JBIC), the Japan External Trade Organization (JETRO), the Nippon Export
and Investment Insurance (NEXI), and the Japan Overseas Infrastructure Investment
Corporation for Transportation and Urban Development (JOIN), in addition to private
corporations that undertake projects. Based on recent changes in the environment
surrounding infrastructure, in December 2020, the ministerial meeting stepped up
its effort and adopted the Infrastructure System Overseas Promotion Strategy 2025
(Figure 1) by including new themes such as response to the COVID-19 pandemic,
contribution to carbon neutrality, and active use of digital technology. Under thisstrategy, cooperation among related ministries and agencies has been promoted.

Figure 1 Outline of Infrastructure System Overseas Promotion Strategy 2025
図 1 インフラシステム海外展開戦略 2025 の概要

The economic cooperation and infrastructure section also developed the Overseas
Expansion Strategy in Disaster Risk Reduction as one of the overseas expansion
strategies for major industries and fields. Experiencing so many disasters for so long,
Japan has accumulated so much knowledge and developed advanced technologies
to fight against disasters. Japan can help other countries establish a safe society andachieve stable economic development by offering practical viewpoints on disasterrisk reduction and high-quality technologies for building quality infrastructure. In
addition, the global disaster-related market is a promising one, for it is expected
to continue expanding, as water-related disasters are likely to be more intense andfrequent due to climate change.
In this strategy, the economic cooperation and infrastructure section created, in collaboration with the Disaster Management Bureau of the Cabinet Office, a catalog oftechnologies and know-how developed in Japan for disaster management (Figure2). The catalog includes a list of preventive actions and measures that should betaken in different phases – pre-disaster, early warning and evacuation, emergency

2018 年 7 月の西日本豪雨や 2019年 10 月の東日本台風（台風第 19 号）
では AMeDAS 地点で観測史上 1 位を更新する降雨観測地点が多発し、広い範囲で河川の氾濫、浸水、土砂災害等が発生するなど甚大な被害がもたらされました。
2020 年 12 月に公表された「日本の気候 変 動 2020（文部 科 学省及び気象庁）」によると、今後気候変動
により豪雨 ( 日降水量 200mm 以上 )の日数が増える一方で降雨日や降雪・融雪が減少することも指摘されています。また、2021 年 6 月に策定された「2050 年カーボンニュートラルに伴うグリーン成長戦略」の中で、未利用の水資源を活用した水力発電の向上が挙げられています。

Extreme rainfall events in western Japan in July 2018 and eastern Japan in October
2019 due to Typhoon Hagibis recorded the highest rainfall in history at many
AMeDAS stations, causing severe flood and sediment disasters at many locations
across the country.
“Climate Change in Japan 2020,” published by the Ministry of Education, Culture,
Sports, Science and Technology (MEXT) and the Japan Meteorological Agency inDecember 2020, points out that the number of heavy rainfall days (over 200 mm/day) will increase, while the number of rainy days and the amount of snowfall andsnowmelt will decrease, due to climate change.
In addition, “Green Growth Strategy Through Achieving Carbon Neutrality in 2050,”
a new policy adopted by the Japanese government in June 2021, addresses the
improvement of hydroelectric power generation utilizing unused water resources.
Under these circumstances, ICHARM has been studying a dam operation method to

ICHARM Newsletter Volume 16 No. 4・January 202210

achieve both flood risk reduction and effective use of water resources by applying
dam water pre-releases based on inflow predictions. The research was conductedunder a MEXT-led project, “The Program to Promote the Development of EarthEnvironmental Information Platform (Development of Water-related Application),”in collaboration with the University of Tokyo, Nippon Koei Co., Ltd., Chubu ElectricPower Co., Ltd., and Tokyo Electric Power Renewable Power Co., Ltd.
In this report, I will present some of our achievements gained in the investigation
conducted for the Hatanagi Daiichi Dam located upstream of the Oi River in Shizuoka
Prefecture, Japan, by citing Koike et al. (2021)1) (hereafter, the paper). The paper
proposed a dam operation method using ensemble inflow prediction and performed
simulations to look into the practicality of the method. The results found that the
proposed operation can work effectively in reducing flood risk and generating more
electricity.
In order to investigate how well dam operations work to control flooding downstream of a dam while improving the effectiveness in power generation, it is necessary
to employ a hydrological model that can seamlessly and quantitatively estimate thebase flow, the peak flow, and snowfall and snowmelt runoff while reflecting theeffect of dam operations at the same time. The paper used a model called “Water
and Energy Budget based - Distributed Hydrological Model-4 component Snow
(WEB-DHM-4cS),” for it can calculate the spatial distribution of the initial hydrological conditions (soil moisture, groundwater level, snow cover, snowmelt, etc.), which
greatly affect the runoff prediction every hour. WEB-DHM-4cS has a considerable
advantage in this respect for estimating the inflow with high accuracy.
After being calibrated for the period from October 2013 to September 2015, WEBDHM-4cS was validated for the period from October 2015 to September 2017 using
the dam inflow data provided by Chubu Electric Power Co., Ltd. The accuracy level ofthe model was evaluated to be a Nash-Sutcliffe coefficient of 0.71 for those four
years.
The paper proposed the basic dam operation using a range width of 32 ensemble
inflow predictions calculated by inputting the data acquired from ensemble rainfall
forecasting (3-km spatial resolution, 1-hour temporal resolution up to 39 hours
ahead, 32 ensembles). The proposed operation consisted of the following five steps:
1) Use the upper 25% ensemble time-series if the priority is flood control, or use thelower 25% ensemble time-series if the priority is securing water for more hydropower generation; 2) check whether the inflow exceeds the amount that can be safely
discharged from the dam during the forecasting period when the dam is operated
under the existing operating regulations; 3) check whether the accumulated inflow
within the forecasting period exceeds the storage capacity at the forecasting start
time; 4) If the inflow exceeds the designated amount in steps 2) and 3), the excess
amount will be released evenly by prioritizing securing water for power generation
within the forecasting period; and 5) If the inflow does not exceed the designatedamount in steps 2) and 3), the average value of the predicted inflow up to 39 hours
ahead will be applied as the amount of water to be used for power generation in thenext hour.
The evaluation index of flood control was set to keep the dam water level below thefull water level when the maximum flood release was set at 600 m3/s. The power
generation was evaluated using the Power Generation Volume Index, which takes
into account the effective head of the amount of water for power generation use.
Figure 1 shows the results of the simulations in which the proposed dam operation
was applied continuously during the warm season of 2018 and 2019 (July to October).
The flood events exceeding 600m3/s occurred twice during the two warm seasons
from September 30 to October 1 in 2018 and from October 12 to 13 in 2019.
Figure 2 shows the details of the two flood events. The 2018 event is a typical casethat may take place when the dam water level is high at the forecasting start time. In
this event, the inflow was predicted while the dam water level was almost the same

as the pre-release water level, and pre-releases were performed on the morning of
the 29th (pink range). As a result, the simulated dam water level (gray dotted line)
decreased, and the simulated peak flow (pink range) was successfully controlled toremain below the 600 m3/s level when the inflow (solid blue line) peaked. If the
pre-releases had not been performed, the gate discharge rate would have exceeded
600m3/s, as shown in the orange range.

the forecasting start time. With the water storage capacity still available, the inflow
was stored effectively up to the full water level (red dotted line) in advance, and thegate discharge was successfully controlled to remain below 600 m3/s. According to
the Power Generation Volume Index, the average power generation during the warm

2019.
The basic dam operation introduced by the paper will be applied to other floodcases to establish stable and reliable dam operations for effective management offlood risk and hydro power generation.

in late November, all 13 students were able to start their studies at ICHARM from
December 6.
During the week starting on December 6, Prof. Emeritus
TAKEUCHI Kuniyoshi of the University of Yamanashi, andMr. WATANABE Masayuki, the president of the Institutefor International Social Development Cooperation,
started a series of lectures entitled “Basic Concepts ofIntegrated Flood Risk Management (IFRM).” It was thefirst face-to-face lecture in two years for Prof. Emeritus Lecture by Prof. Emeritus TAKEUCHI
Takeuchi, who had to give all lectures online last year Kuniyoshi of the University of Yamanashi
due to the COVID-19 pandemic. He also gave a special 竹内邦良山梨大学名誉教授による講義
lecture on NINOMIYA Sontoku, Japan’s famous social reformer in the 19th century.
The students learned how the spirit of Sontoku has been inherited in ICHARM’s mission of “Localism and Empowerment.”
Mr. WATANABE lectured under the title of “Application examples of IFRM overseas.”
The students were given an assignment in advance to read a book, “PROVIDENCE
WAS WITH US,” written by the late Mr. NAKAMURA Tetsu, who was a doctor andthe leader of Afghanistan’s green project but unfortunately shot in Afghanistan in
2019. The lecture was designed for the students to learn how to foster a “sense of mymatter“ in people regarding disasters by analyzing the situation in their country withreference to the purposes and effects of the green project.
● Inception Report Presentation
On October 18, the students presented inception reports, explaining their organizations, the work they were in charge of, and the issues facing their countries. After
their presentations, supervisors and other researchers at ICHARM gave presentations
on their research topics and had discussions with the students about the topics theywanted to work on. It was an excellent opportunity for them to talk about the directionof their thesis research with experts at the beginning of the course.

Sontoku, who restored many towns and villages that had been devastated by floods
and famines, using his rich knowledge and experience about agriculture and civil engineering. They also mentioned his unique management skills, which were embodied
in his four teachings: “Act sincerely to others,” “Work hard to repay for the virtue ofothers,” “Keep the living standard within your income,” and “Invest the residuals forthe future.”<December 15-17: River basins in the Shikoku region>
In mid-December, accompanied by ICHARM Executive Director KOIKE Toshio andResearcher MIYAMOTO Mamoru, the students took a four-day study trip to Shikoku,
a region located southwest of the mainland of Japan.
On the first day, at the Ishii Disaster Prevention Station in Ishii Town, Tokushima
Prefecture, the students learned water disaster prevention and mitigation methods
from Shikoku disaster prevention experts and the staff of the Tokushima River and
Highway Office of the Ministry of Land, Infrastructure and Tourism (MLIT). First, theyreceived an overview of the Yoshino River, a first-class river system that runs throughKochi and Tokushima prefectures and one of the three most violent rivers in Japan.
After observing flood prevention methods, such as
the sand-bag ringing method and the sheet-covering
approach, they received practical training in rope work,
which is essential for flood prevention activities. After
that, the students moved to Kagawa Prefecture, where
they received a brief explanation about Mannoike (Lake
Manno), one of the largest reservoirs in Japan, by an Exercise on rope work at Ishii Disaster
Prevention Station
official of Kagawa Prefecture and the secretary general
石井防災ステーションにてof the Mannoike Land Improvement District.
ロープワーク実習
On the second day, the students moved to Kochi Prefecture and received an explanation about the Sameura Dam from an official of the Japan Water Agency. The Sameura
Dam, completed in 1973 as part of the Yoshino River Comprehensive Development
Plan, is the largest multi-purpose dam in western Japan. As the “water reservoir of
Shikoku,” it supports the lives and industries in the region and reduces flood damage
in the basin.
The students then visited the Nagoya chinka-bashi (“submersible bridge”) over the
Niyodo River in Hidaka Village and a commemorative statue of HIROI Isami, who laid
the foundation for modern civil engineering in Sagawa Town, his birthplace. After that,they went to the construction site of a new Kusaka River floodway and listened to an
explanation by a staff of the Kochi River and Highway Office of MLIT in Hidaka Village.
Since the slope of the riverbed of the Kusaka River is extremely gentle (about 1/3,000),
floodwaters do not flow down easily to the mainstream of the Niyodo River, causing
frequent inundation damage. Although two floodway tunnels have been constructed,
they could not prevent the extensive flood damage caused by the typhoons that hit
the area in August 2014, which led the government to build the third floodway. The
construction is scheduled to end in the next fiscal year, with the total floodway length18.5 km, the longest in Japan.
On the third day, at the Mt.
Godai observation deck,
which offers a panoramic view of Kochi City, thestudents received a brief
explanation from officials

December 2018, has kindly contributed the following article to this issue.

Robin Kumar Biswas

Superintending Engineer (Civil), Directorate of Planning-III
Bangladesh Water Development BoardI spent seven stimulating years in Japan, starting from 2009. ICHARM is a place where I
spent most of my time in Japan. ICHARM started its journey of an international education
program in 2008. I became acquainted with ICHARM in 2009 when I joined the Disaster
Management Program as a postgraduate student. After that, ICHARM became an important part of my professional development. No matter where I am, I always remember
the numerous sweetest memories of ICHARM. I consider myself very fortunate that myresearch endeavors have been in parallel with ICHARM’s success.
I joined ICHARM’s Ph.D. program in 2013 and began to work with Prof. EGASHIRA Shinji. In Sanskrit, a teacher iscalled ‘adhyāpaka,’ whose sole business is not to teach, preach, instruct or advise but to guide, help or facilitate
an aspirant to attain the true knowledge by transcending the limitations of instruments, as well as to enlighten
them to seek the truth incessantly. Prof. EGASHIRA Shinji was more than a Ph.D. supervisor to me. I always feelproud to introduce myself as one of his students.
In the Ph.D. program, I studied the suspended sediment transport process, the morphodynamics of megarivers, and numerical modeling. I learnt the fundamentals of channel changes in braided rivers and proposed amodification to the erosion rate term by including the lateral bed slope. I also proposed a bank erosion model
capable of computing the bank shifting using coarse-sized grids. Afterward, I worked at ICHARM as a research
specialist for two years from December 2018, studying river bed evolution and sediment sorting during a large
flood event and how to assess their impacts on the stage-discharge relationship.
After returning to Bangladesh in December 2020, I joined the Bangladesh
Water Development Board (BWDB) as an executive engineer (Civil). Since then,I have been working at BWDB. Last February, I was promoted to superintending engineer (Civil). Assuming the charge of the Directorate of Planning-3 of
BWDB, my first mission was to complete the execution of the Dutch-aided Blue
Gold Program (BGP). The BGP aimed to reduce poverty in the coastal area byenhancing the livelihood of the rural population through more efficient water
resources management and also to increase the productivity of crops, fisheries, and livestock in the polders by empowering the communities to be thedriving force. The execution of the BGP’s activities started in 2013 and ended
in December 2021. Recently, I made the final presentation on the BGP in thepresence of the State Minister of the Ministry of Water Resources, Bangladesh,the Dutch Ambassador, and other high-level government officials. I also provided a lecture on Participatory Water Management in a workshop arranged
outcomes of the BGP in the presenceby the General Economic Division of Bangladesh. The details of the BGP are Presentingof State Minister, Ministry of Water Resources

Bangladesh lies in the deltaic deposits of the Ganges-Brahmaputra-MeghnaRiver system, which is more commonly known as the Bengal Delta, the second
largest delta in the world. Every year, these rivers carry about one trillion cubic
meters of water and one billion tons of sediment. The huge amount of sedimentis the main driver behind the dynamic morphological nature of our rivers. The
mega rivers in Bangladesh, such as the Ganges and the Brahmaputra, are very
dynamic. It is difficult to manage such rivers without solid scientific research.
Recently, I have initiated a research project aiming to conduct hydro-morphological analysis for identifying the dynamic behavior and erosion-accretion
pattern of sandbars in the Jamuna River. The total cost of this research projectis 4450 million Bangladeshi Taka. Under this project, attempts have been undertaken to prepare an inventory of the sandbars and identify the zones where thespatio-temporal changes of the sandbars are most frequent.
Bankline shifting and avulsion are frequent phenomena. The alluvial floodplainsof the rivers are prone to erosion as they are composed of highly unconsolidated and erodible sediment. Monsoon floods associated with severe riverbank
erosion occur across the country every year, affecting thousands of hectares of
those floodplains. Erosion prediction for medium rivers holds crucial importance,
just like it does for large ones. For this reason, I have also started a research
project for riverbank erosion prediction and vulnerability assessment for the
medium rivers of Bangladesh. Nine medium rivers have been selected for thisstudy, including Teesta, Atrai, Ichamati, Pungli, Dhaleshwari, Arial Khan, Gorai,
Kaliganga, and Sangu. The development of such a prediction system involves
planform analysis using satellite images and mathematical modeling. I am also
involved in research projects on integrated water management and climate
resilient infrastructure and livelihood for the coastal population. The projects
also include sediment management in a tidal river. It is worth mentioning that
I have been nominated as a member of the ICID Asian Regional Working Group(ASRWG) by the Bangladesh National Committee of ICID (BANCID). ICID stands
for the International Commission on Irrigation and Drainage.

Selected medium rivers for erosion
forecasting in Bangladesh

At ICHARM, I had the privilege of meeting excellent mentors, supervisors,researchers, friends, and expert colleagues. The precious experience of working
with an outstanding research group has enabled me to connect with researchers around the world and also contributed to easing my work in Bangladesh. I
still miss after-lunch badminton at the entrance hall, smiling faces of the staff,
thought-provoking discussions with experts’ groups, the warm welcome of
fellow researchers, and a lot of support from experts. I wish every day that I
could join them again.
Currently, the whole world is facing the consequences of the COVID-19 pandemic. I am happy to learn that all the members of the ICHARM family are safeand healthy and have been able to continue their research endeavors. I lookforward to working together again. My heartfelt thanks to ICHARM’s educationand capacity building program.

Editor's Note
編集後記

新年あけましておめでとうございます。
皆様にとって 2021 年はどのような年でしたでしょうか。日本では新型コロナウイルス感染症の拡大に伴って緊急事態宣言が年初より発出されており、出口の見えない状況が続きました。そのような中ではありましたが、1 年延期された東京オリンピック・パラリン
ピックが７－ 8 月に開催され、大きな希望を与えてもらいました。
年末に向かっては、新たな変異株の出現に警戒しつつも、感染者数の急増には至っておらず、徐々に日常生活が取り戻されつつある、
そんな 1 年でした。ICHARM においても、新規修士学生全員が無事入国し、対面での授業をスタートしました。

Happy New Year!
I hope that all readers had a nice 2021. From the beginning of 2021, Japan wasunder a state of emergency in response to COVID-19 wildly spreading acrossthe country. Despite such a situation, the Tokyo Olympic and Paralympic Games
took place in July and August after one year of postponement, and the world was
moved by the performance of athletes. Luckily, the country did not see a drastic
increase in infections toward the end of the year. While still highly alerted abouta new variant spreading around the world, people in Japan were finally able tostart getting back to normal life after a long, depressing time, though very slowly.
ICHARM welcomed all new master’s students and began classes in person, largely
as scheduled.
Though much attention currently tends to be paid to COVID-19, disasters did
occur during 2021 just like they had in the past. In Japan, a massive debris flow
occurred in Shizuoka Prefecture after heavy rain in July. An extreme rainfall event
brought about tremendous damage in the Kyushu area in August. There weremany disasters worldwide, too. In July, for example, extremely severe floods hit
Germany and Belgium. I truly hope that the world will not see such catastrophes
in 2022. In the meantime, ICHARM will work hard to continue making progress in
our research and other activities to contribute to disaster risk reduction aroundthe globe.
May this year be filled with happiness and hope for all people around the world.
ICHARM is looking forward to expanding further collaboration with you!
