【摘要】:選取黃河中游清涼寺溝和佳蘆河為典型支流,采用1980—2013年的歷史洪水資料,基于霍頓下滲能力曲線建立產(chǎn)匯流模型,率定出產(chǎn)匯流參數(shù),供府谷—吳堡未控區(qū)借鑒使用;基于ArcGIS將府谷—吳堡未控區(qū)劃分為20個(gè)單元,分析各單元馬斯京根法參數(shù),對(duì)該未控區(qū)歷史典型洪水進(jìn)行模擬。結(jié)果表明:模擬效果較好,平均峰現(xiàn)誤差為-0.4 h,洪峰誤差均在預(yù)報(bào)允許范圍之內(nèi),確定性系數(shù)為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.
