To help you understand how it can be used and operated, we have provided several
simulation examples, including videos.
No ID registration required
Anyone can check the registered simulation results. You can select the results you want to see on the map and check the flooded area in animation.
ID registration required
When considering climate change adaptation measures, you can easily simulate flooding in rivers, cities, and coastal areas. If you need the ID, see GETID.
When using the simulation function, please fill out the necessary information and send it to the inquiry email address.

MERIT DEM / Hydro
FloodS uses global 90m resolution terrain data constructed by the University of Tokyo. By using this data, you can run simulations anywhere you like.
FloodS uses global 90m resolution hydrographic data constructed by the University of Tokyo. By using this data, it is possible to easily input information for river flooding simulation conditions.
FloodS uses high-precision topographical data with a resolution of 2.5m provided by RESTEC and NTT Data in some areas. By using this data, highly accurate simulation results can be obtained. You can check the adopted areas by pressing the AW3D button on the screen. In the video below, pins are set in the area where AW3D is set.
FloodS uses the flood simulator “DioVISTA/Flood” provided by Hitachi Power Solutions as its simulation engine. By using this engine, you can obtain simulation results using high-speed flood calculations. DioVISTA/Flood is a desktop-based software that is used by many professional engineers. Users include civil engineering, architecture, property and casualty insurance, disaster management, corporate business continuity planning, and education, etc. DioVISTA can couple 1D river models, 2D inundation models, and runoff models. The simulation is integrated with a 3D geographic information system, making it possible to create models, run simulations, and analyze simulation results as intuitively as if you were manipulating a map.
