Application of design hyetographs to estimate stormflow hydrograph of Chungliaoshi watershed

In thsi paper the curve number of SCS method was established using storm rainfall and stormflow data of Chungliaoshi watershed at Liukuei experimental forest of Taiwan Forest Research Institute. Data of storm rainfall and stormflow at Chungliaoshi watershed were measured from June to September during 2002-2005. Then, the rainfall excess from 24-hour rainfall of different recurrence years in Chungliaoshi watershed was calculated by SCS curve number method. The stormflow hydrographs of Chungliaoshi watershed were estimated with triangular unit hydrograph and design hyetograph estimated equations.

本文以台湾林业试验所六龟实验林区忠寮溪流域的暴雨降雨与暴雨径流实测数据为基础，率定了SCS法（SCS method）的曲线数参数。该流域的暴雨降雨与暴雨径流数据采集时段为2002年至2005年的6月至9月。随后，采用SCS曲线数（SCS Curve Number）法计算了忠寮溪流域不同重现期24小时降雨的净降雨量。此外，结合三角形单位线与设计雨型（design hyetograph）推求公式，估算得到忠寮溪流域的暴雨径流过程线。本研究成果发表于《坡地灾害防治学报》2006年第5卷第1期，页码范围1-14，原论文标题为《应用设计雨型推求忠寮溪流域暴雨径流过程线》。
