Our research focuses on flood disaster and mainly on numerical simulation.
In the future, we hope to conduct an observation, but we are currently focusing our efforts on the following topics:

(1)The development of a Distributed Rainfall-Runoff / Flood Inundation Simulation

(2)Research on a flood insurance (in collaboration with a private insurance company)

(3)The development of a 'real-time' flood prediction system

(4)The development of a highly accurate flood model

(5)Research on evacuation design using an evacuation activity model

(6)Research on integrated 'real-time flood' forecasting and use of the "K" supercomputer in the engineering field

(7)Research on flood risk changes due to climate change (in collaboration with the Climate Change Project, Kyoto University, and others)

(8)Participation in the SATREPS Ghana project (in collaboration with Tokyo University, UN University, and Kyoto University)

The Distributed Rainfall-Runoff / Flood Inundation Simulation model is intended for the Kansai area (Yodogawa), the Kanto area (Tonegawa, Arakawa, Tamagawa) , and the Chubu area (Kisogawa, Shonaigawa).
This model focuses on the traceable rainfall-runoff mechanism, and the flood mechanism.
Using it makes it possible to calibrate the depth in any drainage basin, and the flow and current state of any river channel. There were many reasons to develop this model. One of the reasons is the necessity to accurately, and objectively estimate the flood risk throughout Japan.
Our research in to flood insurance, is in collaboration with a private insurance company; namely, Sonpo Japan NKSJ risk management.We also use this model to develop a 'real-time' flood forecast system.
When used over a wide area, including the country side, this forecast system enables the efficient use of computational resources. To encompass regional variations, we simultaneously develop a detailed inundation model.
We develop an 'evacuation-activity' model from the calculated results of the 'wide-area' model.

Our research is in the field of 'ensemble flood forecasting' utilising the "K" supercomputer in association with the Meteorological Research Institute, Kyoto University, and JAMSTEC.
The project will continue for four years. Our aims are to explore the meteorological model, with special emphasis on its adaptation, and implementation, as an flood forecast model.A new climate change project has been launched.
It will assess the variation in flood risk resulting from the impact of climate change.
It is a JICA-JST project intended for Ghana in collaboration with Tokyo university, Kyoto university and UN university.
This project will also continue for four more years.
The research aims to assess and forecast climate change and the variations in resultant flood risks for the Volta river in Ghana.In addition to the research projects noted above, other research and projects are on-going.
We are currently recruiting suitable candidates.
