Modeling Sediment Transport and River Bed Evolution in River System

Wanshun Zhang, Yanhong Xu, Yanru Wang, and Hong Peng
Abstract—The problem of sedimentation has significant impacts on the operation lifetime of the reservoir. A two dimensional numerical model has been developed to simulate the transport of sediment and the evolution of the river bed in river system. The model consists of hydrodynamic equations, sedimentological equations and bed deformation equations. Water-sediment conditions and the abrupt change of water level and flow, which are influenced by gate dams, were emphatically considered in the simulation. The field measurements of erosion-sedimentation thickness of 2006, 2007, 2008 and 2009 in three sections are used for the model validation and the simulation results agree with the measurements well. The model is applied to simulate the process of sediment deposition at the upper reaches of Three Gorges Reservoir Region. The model results can reflect the detailed changes of sediment deposition thickness of river channel in the next 70 year.

Index Terms—2D mathematical model, erosion and deposition, sediment, Yangtze River.
