Explore three-dimensional water-cycle models at national and global scales through public viewers and technical overview pages. This site is an entry point for viewing connected surface-water and groundwater behavior on maps.
The national model integrates terrain, rivers, lakes, geology, soils, land use, meteorology, vegetation, and observations across Japan. It represents connected surface-water and groundwater processes in three dimensions. The Webmap publishes model outputs at a representative resolution of approximately 500 m.
The global model integrates worldwide terrain, rivers, lakes, geology, soils, land use, meteorology, vegetation, and observations. It represents connected surface-water and groundwater processes in three dimensions. The Webmap publishes model outputs at approximately 20 km global resolution.
Inspect rainfall, recharge, groundwater flow, and river discharge in an interactive 3D view.
