The need of our era by sedimentation to accumulate in the dam reservoir is the large-scale and urgent difficulty to become a evidence impeding the reasonable utilization of water resources, which in also have ecology, leisure, economy and variety of a lot of nature.} Due to the amplifying adverse effects of determining effects of the resultant behavior to storage, continuous sediment-quality damage, and possibly dam structure-life damage, immediate requirement of sustainable siltation-remediation strategies based on new sediments therapeutic method has been valid. One of the most successful and common methods for clearing sediment from dam hoisting and accumulation is hydraulic flushing. This technique involves the simulated and controlled release of water from the bottom outlet of a dam to detach and carry sediment which has been settled over a long period of time. This paper is intended to review the approach and principle on hydraulic flushing, field implementation and a variety of the case studies of using hydraulic flushing: A Tool for Sediment Management in Reservoirs. It examines different kinds of flush (isolation valve, water hammer, scavenger, back-pulsing and dredging), measuring their sediment removal capability and the technical and ecological issues concerning such a remedy. Moreover, this review not only summarizes the success stories of globally implemented hydraulic flushing projects but also discusses the knowledge gaps in the current literature that may provide potential insights to improve future sediment management practices. Following a brief introductory section that describes sedimentation issues in reservoirs, this paper
