尊村引黄灌区是山西省一座大型多级提水灌溉工程.由于所引黄河水的泥沙含量较高,导致灌渠泥沙淤积问题十分严重,影响到了渠道的正常运行.为了掌握灌区渠道水沙分布规律,缓解渠道淤积问题,在尊村二干渠设立7个观测面开展泥沙含量与粒径级配观测和分析.研究结果可为灌区管理和节水减沙工作提供参考依据.%Zuncun Irrigated Area of Yellow River Diversion Project is a large multistage project for irrigation in Shanxi Province.Because of the sediment concentration of the Yellow River is higher,the sedimentation problem of irrigation canal is very serious,affecting the normal operation of the canal.In order to grasp the irrigation canal of distribution regularity of water and sediment and ease the aggradation of canal,seven observation surfaces in Zuncun secondary trunk ditch was set up to monitor water and sediment in this study.The study results can provide a basis for irrigation district management and water-saving and sediment reduction.
