Flood simulation using global DEM (NASA SRTM3)

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 assessment

Image

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.
