Message from professors

Prof. Taikan OKI

The mission of our research group is to advance the science related to water cycles and their management and disseminate the achievements to society. We are engaged in research that contributes to solving water issues such as floods, water disaster, drought, and water scarcities both in the world and in Japan, reducing the adverse impacts of climate change, and building sustainability globally. With the power of diverse academic knowledge and technologies, we carry out researches that pioneer new academic systems and contribute to the maintenance or enhancement of safe, comfortable, healthy, and cultural well-beings.

Visiting Prof. Naota HANASAKI

We conduct research on the relationship between the natural water cycle and human water use and management from various scales and aspects. Our research approaches range from global-scale water and environmental issues, such as what will happen to the world’s water resources and water use if global warming progresses, and what will be the impacts on the world if Japan and other countries import large quantities of food, to fundamental questions such as what determines the current distribution of agricultural land, and whether the flow of rivers can be simulated from more than 100 years ago.


Senior Research Fellow Masashi KIGUCHI

We study hydro-meteorological phenomena such as rainfall in terms of monsoon circulation with an important role in the global water cycle. The Asian monsoon, which provides abundant rainfall, plays a part of the global water cycle, and is important to human activities like rice cropping, domestic water for a large population, and industrial water which supports rapid economic growth. Its seasonal and annual variabilities have a big impact on our society. To make clear an impact on society by its variability through the research on monsoon variation from the viewpoint of climatology and hydrology provides the scientific knowledge for the issues of how society should cope or which kind of policy is effective.


Assis. Prof. Masashi MINAMIDE

My research interests lie in exploring the predictability of weather system and deepening the understanding of their dynamics using the latest observational, modeling, mathematical, and statistical methodologies. During my doctoral study, I have conducted research through building a platform to assimilate all-sky infrared satellite radiances using an ensemble Kalman filter with convective-permitting models, developing new methodologies required for cloud-affected radiances assimilation, and investigating their impacts on the predictability of severe weather events such as tropical cyclones.


Assis. Prof. Kanon KINO

We’re researching climate change throughout the past, present, and future. Using climate models employed in IPCC (Intergovernmental Panel on Climate Change) reports, we simulate climate changes from historical eras before instrument observation started. This allows us to consider the role of human activity throughout the Earth’s history. If you’re interested in history while willing to take a scientific approach, or if you wish to understand climate change from a multifaceted perspective, we’d love for you to join us in our research! Let’s explore together!


Assoc. Prof. Yohei SAWADA

We are exploring new technology to observe the current state of both natural and social spaces (e.g., weather, hydrology, transportation and conomics), predict its future and control social infrastructures based on the prediction to protect our society from crises such as floods and droughts. We are investigating statistical mathematics to integrate numerical simulation and observation data to deepen our understanding of the coupled nature-social system. Let’s enjoy the cutting-edge of engineering research in which basic science is applied to social issues!

Assis. Prof. Le DUC

We are interested in introducing ideas from multi-disciplines including data assimilation, probabilistic numerics, optimal transport, to name a few, into earth sciences. This interdisciplinary approach sheds light on open questions and usually yields unexpected and many times elegant solutions. By this thinking across boundaries, we hope that students can extend their knowledge, and grasp a big picture of the fields that they pursue.


Prof. Akiyoshi KAWASAKI

Our group is engaged in research and policy support on flood control and disaster risk reduction investments as climate adaptation measures to address socioeconomic problems, such as poverty and rising inequality in the Global South. Based on the engineering approach of quantification and modelling, we conduct field-based,interdisciplinary research in collaboration with experts in economics, history and cultural anthropology, as well as development agencies. Focusing on hydropower dams as a means to this end, we also undertake engineering research on dam control in the context of climate change,including flood control measures.

Reclutes

To those interested in studying at our graduate school

This laboratory belongs to Graduate School of Engineering, Department of Civil Engineering Students can be assigned to this labratoly from the Hydrosphere and Environment Group. This group is composed of River and Environmental Engineering Laboratory, Coastal Engineering Laboratory and Global Hydrology Group in the IIS.
The graduate school entrance examination briefing session is held in May every year. The supervisor will be determined based on the research theme. The Hydrosphere and Environment Group are welcome for your participation from other disciplines. As the theme of this laboratory is mostly interdisciplinary, the experiences of other fields will be useful. There are many professors and OB/OGs from other universities, faculties and departments.
If you are interested in, please feel free to contact us.

 

To undergraduates who wants to be assigned to this laboratory for graduation thesis

Students are assigned from Department of Civil Engineering.
Among the Hydrosphere and Environment Group, it depends on the year, about 5 people are assigned to River and Environmental Engineering Laboratory. The instructor is determined by the student’s wishes and themes.
