三、报告摘要

Understanding the dynamics of surface water in rivers and lakes is essential for water sciences. While many regional-scale studies focusing on specific river basins are very important, global-scale monitoring and prediction of the surface water dynamics including storage, discharge, water level and inundation extent were not paid much attention for a long time. In order to simulate the surface water dynamics at a global-scale, Prof. Yamazaki had developed the global river hydrodynamic model “CaMa-Flood”, which simultaneously represents large-scale water balance and small-scale floodplain inundation dynamics by treating detailed topography as sub-grid parameters. This multi-scale modelling approach is computationally very efficient, and large-scale flood simulation becomes at least 10,000 times faster compared to conventional 2D flood models while the accuracy of simulated hydrodynamics is kept at similar levels. In this talk, Prof. Yamazaki will review the history of CaMa-Flood and its baseline dataset development. Future perspectives of global surface water studies considering the advantage of these recent developments in modelling studies, including the very latest activities on model-satellite integration, will also be presented.

四、专家简介

Dr. Dai Yamazaki is an associate professor at the Institute of Industrial Science, The University of Tokyo, Japan. He has been working on the development of a global-scale river hydrodynamics model. The “CaMa-Flood” global river model developed by Dr. Yamazaki and his colleagues is now widely used for earth system modelling and global flood risk studies by many research teams in the world. His major outcomes, named MERIT DEM & MERIT Hydro, are publicly available for research & education purposes, and he has provided the datasets to more than 3000 scientists for collaborative researches such as on flood simulations, land hydrology modelling, and hydro-bio-geochemistry. His academic contribution was honored with multiple awards, including “JSPS Ikushi Prize” (2012) and “The Commendation for Science and Technology by the Japan Minister of Education, Culture, Sports, Science and Technology” (2019).
