Levee breach process
Efficient of river channel characteristics
It is important mitigating flood damage by overflow from a levee breached. The mechanism of levee breach has not been clarified. This study aims to clarify the below point, the effect of river channel characteristics on levee breach processes by using a numerical model to simulate levee breaches based on results of the experiments. The results of the simulation are as follows: In the case of Froude number becomes larger, levee breach widening is dominant. In the case of Froude number becomes smaller, river bed erosion is dominant. And the phenomenon switches when the Froude number is about 0.5.
