Applied SMS-2D in Erosion Simulation of High Entrained Sand Flow Field during Severe Typhoon

Taiwan shaped to the narrow island, whose topography and climatic factors affecting the subject, river current is swift and steep riverbed erosion phenomenon is quite serious, this study Kaohsiung Baolai No.2 Bridge in southern Taiwan as an example and SMS-2D numerical model to simulate flow field during severe typhoon, and thereby calculate the scour depth around pipes by high sand silting, the riverbed elevation change after typhoon can be accurately simulated and provides references of related projects.
