Advance and prospect in research on reservoir sediment control and functional restoration

Almost all the reservoirs in the world face the problem of sediment deposition, which has become an urgent technical problem to reduce the function, safety and comprehensive benefit of the reservoir. The long-term conservation and sustainable utilization of the reservoir and the effective restoration of the capacity of the deposition loss become an important way to solve the water shortage. This paper briefly introduces the basic research progress of reservoir deposition at home and abroad in recent years, discusses the reservoir sedimentation control and function recovery techniques from three aspects of incoming sediment reduction, hydrodynamic desilting and recovery of silt capacity. In future, it is necessary to study on the sediment movement process under the joint action of hydrodynamic and artificial measures, develop the techniques of volume recovery and sediment treatment and utilization of silt reservoir, establish reservoir function impact assessment model, and put forward reservoir functional recovery measures and strategies for different types of regions. © 2018, China Water Power Press.
