Global Hydrodynamics Lab (PI: Dai Yamazaki) is a part of U-Tokyo Global Hydrology Group in Institute of Industrial Science, The University of Tokyo.

Yamazaki lab is in U-Tokyo Komaba-2 Research Campus (Map, Directions) in central Tokyo.

Our studies mainly focus on the dynamics of land waters on the global scale, using modelling, remote sensing, and data integration approach.

What is Global Hydrodynamics?

“Global Hydrodynamics” is the study of the dynamics of terrestrial waters over the entire Earth.

It focuses on the movement and storage of the surface and sub-surface waters at multiple temporal and special scales from local to global, including rivers, lakes, wetland, soil moisture, and groundwater. It also covers their interactions with related earth surface processes, such as precipitation, evaporation, coastal and ocean dynamics, biogeochemistry, climate change.

We extensively use modelling, remote sensing, and data integration approaches to cover the entire globe, while we also respect in-situ observations to determine important processes in global hydrodynamics and to ensure the robustness of the model conceptualization.

In addition to natural hydrological cycle, we also assess the impact of the terrestrial water variability to the human well-beings (e.g. flood, water resources, ecosystem service), and try to understand the reactions of the society (i.e. water resources and hazard management) and their feedback to the global hydrodynamic system.

Who are we?

Our lab is one of the world-leading hydrological science bridgeheads, consists of researchers and students with multiple backgrounds (Earth science, civil engineering, geography, spatial information science, computational science, etc.)

All research staff members belong to Institute of Industrial Science, while we also commit to education in the Department of Civil Engineering.
