根据黄河上游流域情况 ,将河网汇流、河道汇流和超渗产流模型结合 ,使其适用于干旱半干旱的公伯峡流域 ,并在缺乏资料的情况下使用最小二乘法和卡尔曼滤波模型实时修正。研究采用改进概念性产汇流模型先将流域分单元 ,再对单元流域进行产汇流计算 ,以考虑水文现象在面上的不均匀性
According to the upper reaches of the Yellow River, the river network convergence, river confluence and ultra-seepage model were combined to make them suitable for the arid and semi-arid Gongboxia basin. In the absence of data, the least square method and the Kalman filter model Real-time correction. In this paper, the improved conceptual model of convergence and runoff generation is used to divide the catchment into units and calculate the catchment and runoff of the unit catchment in order to consider the inhomogeneity of hydrological phenomena on the surface
