Abstract
In view of the sedimentation problem of Kezier Reservoir in Xinjiang Uygur Autonomous Region, the dike-canal joint desilting system was put forward. After the system was constructed, trunk streams and tributaries are separated; flow environment is improved; silt-carrying capability of water flow is strengthened; silt route of Heizi tributary is shortened, so it becomes easier for the density current in tributary with high silt content to reach the main dam. The sediment discharge data of 2007 and 2011, respectively before and after the construction of dike-canal joint desilting system, had been compared and the results demonstrate that after the construction ,the travel distance and time of silt-carrying flow in reservoir area are shortened;sediment discharge from the reservoir increases;sedimentation in reservoir decreases;and the service life of reservoir is prolonged with significant bene⁃fits.关键词
