杜尔哈斯蒂（DUIHasti）水电工程位于喜马拉雅地区地势较低、输沙量很大的一条河上，尤其在洪水期（季风降雨期）输沙量更大，该工程的蓄水库容（活库容和死库容）很小。为了拦截90％以上粒径超过0．33mm的沙粒，根据理论方法设计了地下沉沙池，并通过水力学模型试验进行了验证和改进。水工模型试验表明，在设计流量123m3／s下，设有扩散段（长48mm）、长240m、断面面积170m2的沉沙池能满足要求。
The DUI Hasti hydropower project is located on a river that is low in the Himalayas and has a large sediment load. In particular, sediment discharge is greater during the flood season (monsoon rainfall period) And dead storage) is small. In order to intercept more than 90% of the sand particles with grain size over 0.33mm, the desilting basin was designed according to the theoretical method and verified and improved through the hydraulic model test. Hydraulic model tests show that, at design flow rate of 123m3 / s, with a diffuser (length 48mm), length 240m, cross-sectional area of 170m2 desilting pool to meet the requirements.
