In this paper,the measurement insitu and computation regarding sediment problem in the irrigation district of Langdian Yellow River Diversion project are made.A definition that the sedimentcarrying capacity of the canal is a relative equilibrium sediment concentration that corresponds to the flow condititon under which the decrement or increment of the scour or deposition in the canal equals nothing has been given.An analogy method of the model similarity is presented for estimating the new canal's...

In this paper,the measurement insitu and computation regarding sediment problem in the irrigation district of Langdian Yellow River Diversion project are made.A definition that the sedimentcarrying capacity of the canal is a relative equilibrium sediment concentration that corresponds to the flow condititon under which the decrement or increment of the scour or deposition in the canal equals nothing has been given.An analogy method of the model similarity is presented for estimating the new canal's sedimentcarrying capacity by the old canal's data measured.Experiences obtained from controlling operation for solving the sedimentation problem of the canal,especially of the upper reaches of the canal in water lifting irrigation district are summarized.However,the conclusion of this paper needs further verification after Langdian Project has been completed.

针对浪店水源工程灌区存在的泥沙问题,进行了原型观测和计算,对灌区水流泥沙运动规律及泥沙利用模式进行了研究,在天然资料缺乏的情况下,提出了以渠道泥沙冲淤量为零(Δqs=0)时水流条件所对应的相对平衡含沙量定义为渠道的水流挟沙能力;采用模型相似类比法,由已建渠道实测资料推求新建渠道的挟沙能力;总结了提水灌区通过调控运行解决渠道特别是渠首段泥沙淤积的经验。

运城地区水资源匮乏 ,提引客水是该区发展水利的主要途径。全区 2 2处大中型提水灌区大都兴建于 6 0、70年代 ,由于受历史条件所限 ,工程建设存在问题较多 ,加之几十年的运行 ,设施老化失修 ,不能发挥其应有的效益。本文对灌区的发展过程和现状进行了认真分析 ,针对存在的问题 ,提出了今后的发展思路
