According to the latest research results of the basic theory of sediment movement , established for unsteady , non-uniform , total sediment mathematical model to simulate the Chongqing reach of cement sand movement and deformation of riverbed . Model based on eddy mode , invert the turbulent viscosity coefficient formula : At the same time , according to the energy balance principle , derived riparian expand equation . The model also introduces a formula The suspended sediment Zhang Hongwu proposed sediment carrying capacity : bed load transport formula and Junhua - Zhang HW : improvement of existing mathematical model of the Three Gorges Reservoir Area . The The the Chongqing Reach the normality model test data and prototype observation data calculated results show that the model calculated along the water level , velocity distribution and Riverbed Erosion and prototype found . Provides a theoretical basis for future studies of river water and sediment movement rule .
