Abstract
<p> In recent years, due to climate change caused by global warming, record-breaking torrential rains have been occurring frequently. In particular, river levee breaches cause serious damage, so investigation of the mechanism of the levee breach is an important issue. In Typhoon No. 19 in 2019, the levee failures caused sediment deposits on the protected lowland, causing extensive damage. Although many studies have focused on sediment transport, the process of topographic changes during a levee breach, including clay and gravel, has not yet been revealed. In this study, we conduct levee breach experiments with simulated levee using colored gravel, and observed in detail the topographic changes during the overflow failure. As a result, it was revealed that the differences of the overflow failure process have a great effect on the shape of levee and surrounding topography.</p>
