本研究利用年百分數流量和年平均逕流量之比與流域面積建立年百分數流量之區域特徵迴歸方程式, 研究中藉區域特徵迴歸誤差之校正, 推求未設站或資料缺乏流量站地點之區域流量延時曲線, 並以南部地區所選九個流域三十九個流量站資料, 經驗證其精確度甚高, 其累積總誤差大都於20%以內。 In this study, the regional characteristic regression function was built by using the ratio of the percentage of yearly flow equal to or greater than indicated flow and annual average discharge versus the watershed area. The flow duration curve of the ungauged and the insufficient data area was simulated by means of the adjustment of the errors of regional characteristic regression function. According to the results of the data from thirty-nine stations of the basins selected in south Taiwan, most of the errors of area under simulated flow duration curve are within 20%.
