Abstract: Reservoir sedimentation is a serious problem to make a reservoir gradually lose its normal function. As a result, the issues of reservoir deposition have been clearly studied and some technological improvements in China have been achieved. The traditional desilting measures for reservoir deposition contain hydraulic desilting, mechanical dredging and some other comprehensive measures. According to the specific condition of reservoir deposition, different desilting equipment and measure are applied. In this paper, the common desilting measures, such as mechanical dredging, empty-reservoir desilting, and density current desilting, flood detention desilting and self-suction sediment transport piping system, are summarized. Those desilting measures� principle, effect and application condition are demonstrated, especially from a high-efficient, low-carbon and environmental point of view. The studies show that self-suction sediment transport piping system has an advantage of improving efficiency, lowering energy, saving water and reducing cost. Moreover, the desilted sediment is easy to be collected and recycled. The desilting that measures about self-suction sediment transport piping system has broad prospects in engineering application
