Sedimentation is one of the key factors affecting the long-term operational efficiency of reservoirs. With the increase in the service life of reservoirs, sedimentation leads to a gradual reduction in the reservoir capacity, changes in hydrodynamics, and affects the regulation ability of the reservoir as well as the effective utilization of water resources. Sedimentation not only reduces the water storage capacity of the reservoir but may also affect multiple functions such as flood control, water supply, and power generation. In order to ensure the normal operation of the reservoir, it is necessary to adopt effective regulatory measures, such as regular dredging, optimizing water storage scheduling, and improving soil and water conservation in the upper reaches. This paper will discuss the long-term impact of sedimentation on reservoirs, analyze the effectiveness of existing regulatory measures, and propose more effective management solutions.
