金盆水库上游降雨径流二维泥沙输移沉积模拟OACSTPCD

In order to investigate the influence of rainfall runoff on the water body of Xi'an Jinpen Reservoir under different discharge and sediment content,the sediment transport and deposition in the upper reaches of Xi'an Jinpen Reservoir during the rainfall runoff period in October 2022 are numerically simulated based on the turbulent flow model,and the reliability of the established model is verified.Through the simulation calculation of runoff with different discharge and sediment content,it is shown that the sediment content at the bottom of the section along the front section is smaller with the higher velocity,and at the rear section,the higher the velocity,the higher the sediment content.The larger the sediment content of runoff,the larger the sediment content of cross section,and the larger the sediment distribution thickness.Therefore,the process of sediment transport and deposition can be analyzed according to the discharge of rainfall runoff and sediment content,which can provide reference for the operation and maintenance of the reservoir.
