Our flood simulator supports evacuation planning and education for disaster-prevention. Our unique algorithm enables to simulate flood disaster quickly on your PC. User interface integrated on our original three-dimensional mapping system enables intuitive operation and visualization.
Our original four-dimensional (latitude, longitude, elevation and time) Geographic Information System easily visualize realistic flooded city.

Our unique calculation method (Dynamic Domain Defining Method, or DynamicDDM) makes flood simulation faster, and enables real time flood forecasting.
A comparison of flooded depth based on our built-in global topography data (NASA's SRTM3 ) with local one (Geospatial Information Authority of Japan's 50 m DEM) suggest the global data has adequate accuracy.
Condition: a flood caused by a levee breach in Tone River (largest river in Japan).

Risk of walking in the flooded water for evacuation is assessed based on inundation depth and velocity.
User can output a simulated result as Hazard map or video (AVI), which are suitable contents to distribute through the internet.
