摘　　要：实测水沙资料是河网水动力模型验证以及泥沙输移计算的基础。然而由于河网河道与支流众多,长期大规模的水沙实测资料相对匮乏。为此对杭州城西河网进行长达一年的水动力实时观测及逐日泥沙取样,并进行了河网全河道联合测量。本文对所获得的详细实测数据进行统计,并对河网水动力及泥沙分布及变化规律进行分析和总结。本文实测数据可作为城市河网数学模型验证资料,同时通过大量实测资料所拟合的浊度与含沙量的关系可为水沙研究提供参考。The measured field data of hydrology and sediment are the basis for mathematical model inriver sediment transport calculation and validation.Long term and large scale measured data in rivernetworks are relatively few because of the great quantity of rivers and tributaries.Therefore real timeobservation of water dynamic and daily sediment sampling were carried out for one year in the rivernetworks,west Hangzhou.Joint measurement of all river channels was included.The statistics wasperformed on the measured data in this paper.In addition to this,the variation on hydrodynamic andsediment distribution was analyzed and summarized.The measured data can be used to validatemathematical model of urban river networks.The fitting relationship of turbidity and sedimentconcentration from a large amount of measured data provides important reference for the research ofhydrology and sediment.
