Abstract：Ensuring storage capacity is crucial for the effective functioning and comprehensive benefits of reservoirs in flood control,power generation,navigation,and water resource utilization.The storage capacity of the Three Goiges Reservoir is a highly valuable strategic resource.This study analyzes measured data to elucidate the characteristics of sediment accumulation in the Three Gorges Reservoir since its operation.Based on the distinct sediment accumulation features in various sections of the Three Goiges Reservoir and appropriate methods for sediment utilization,an overall plan for the classification and utilization of sediments in different sections of the Three Gorges Reservoir is proposed.It is recommended to prompt develop a comprehensive implementation plan for dredging and utilizing sediment in the Three Gorges Reservoir,progress with pilot projects for sediment removal and sand discharge in key sections and gradually extend implementation,and delve into research on cost-effective material utilization technologies for sediment,providing support for the safety of reservoir capacity and the sustainable realization of comprehensive benefits.
