FAQ/ Error countermeasures for levee flow rate calculated by levee failure model

If you use the overflow formula in a levee model, the calculated breakage flow rate may exceed the river flow rate.

Do you have any measures in place in that case?

response

The flow rate of the floodplain from a certain river channel section can be adjusted so that the water depth of the river channel section does not become negative.

With this setting, if a negative depth of the river channel is detected, the time step is reduced and the calculation is recalculated.
