Dai Yamazaki Dai Yamazaki is Associate Professor at Institute of Industrial Science, The University of Tokyo. He has been working on the development of a global-scale river hydrodynamics model, focusing on how to simultaneously represent the continental-scale water balance and local-scale flood dynamics. 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. He also made significant contributions to the development of high-quality global hydro-topography maps which are used as baseline data for earth science, such as flood simulations, land hydrology modelling, and biogeochemistry. He is also working many other topics such as remote sensing of surface waters, Earth system model development, climate risk information. 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, 2021), and AOGS Kamide Lecture Award (2020).
