【摘要】：选取黄河中游清凉寺沟和佳芦河为典型支流,采用1980—2013年的历史洪水资料,基于霍顿下渗能力曲线建立产汇流模型,率定出产汇流参数,供府谷—吴堡未控区借鉴使用;基于ArcGIS将府谷—吴堡未控区划分为20个单元,分析各单元马斯京根法参数,对该未控区历史典型洪水进行模拟。结果表明:模拟效果较好,平均峰现误差为-0.4 h,洪峰误差均在预报允许范围之内,确定性系数为0.66。
[Abstract]:Selecting Qingliangsigou and Jialu River in the middle reaches of the Yellow River as typical tributaries, using the historical flood data from 1980 to 2013, the model of production and confluence was established based on Horton infiltration ability curve, and the yield confluence parameters were determined for use for reference in Fugu Wubao uncontrolled area. Based on ArcGIS, the uncontrolled area of Fugu and Wubao is divided into 20 units, and the parameters of each unit are analyzed, and the historical typical flood in this uncontrolled area is simulated. The results show that the simulation effect is good, the average peak error is -0.4 h, Hong Feng error is within the forecast allowable range, and the deterministic coefficient is 0.66.
