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.
