FAQ/ Breakage Model Specifications

Please tell me the specifications of the levee model.


This is a compliant levee model in the Flood Assumption Area Mapping Manual (4th Edition).

However, the ground height inside the levee at the time of levee breach is evaluated with the nearest 1 mesh.

You can set the breach start water level, the breakage width time series, the breakage height time series, etc. In addition, the transverse overflow coefficient can be set according to the formula of Kurishiro etc.

An example configuration is shown in the figure.
