Zusammenfassung:It is important to mitigate flood damage by overflow from a levee breached. The mechanism of levee breach has not been clarified. This study aims to clarify the effect of channel cross-section on levee breach processes by using a numerical model developed for levee breaches based on experimental results. The numerical results show that the mechanism of levee breach is qualitatively the same in single cross section and compound cross section.
