Abstract:
Reservoir sedimentation affects the reservoir benefits and threatens the reservoir life. Based on the basic equations of the hydrodynamic and sediment mathematical model and under certain assumptions, the one-dimensional model of non-uniform flow and non-equilibrium sediment transport model was simplified, and the model parameters were calibrated and verified using the observed data of the reservoir. In this paper, the model was applied to Yayangshan Reservoir and verified the parameter feasibility according to the measured data in the reservoir, which can provide reference for the sedimentation calculation of the Yayangshan Reservoir in future.
