Abstract: A two‐dimensional model is applied to calculate bed variations in alluvial channels. The depth‐averaged flow field is obtained from a steady‐state, two‐dimensional shallow water flow model, and the bed variation is calculated ...

Abstract: This study aims to clarify the mechanism of riverine levee breach and propose a new numerical model for that phenomenon. Large-scale experiments of overtopping breach were performed using an experimental flume located on ...

Abstract: A two-dimensional numerical model was developed to simulate relatively wide, shallow rivers with an erodible bed and banks composed of well-sorted, sandy materials. A moving boundary-fitted coordinate system was used to ...

Abstract: A three‐dimensional (3D) flow model is developed to improve the defects of a two‐dimensional (2D) model proposed by Shimizu and Itakura. Calculated results are compared with experiments as well as with results calculated ...
