全國 112個 貯水池를 對象을 流域因子間의 關係 및 流域因子와 尖頭流量과의 關係를 調査·分析한 結果 다음과 같은 結論을 얻었다. 1. 流域面積과 主河川長, 流域面積과 流域의 周長, 流域面積과 支流總延長, 主河川長과 流域의 周長, 主河川長과 河川重心長, 主河川 平均傾斜와 流域의 平均標高와의 關係를 相關分析하여 相互間의 相關關係式을 誘導하였다. 2. 각 流域因子와 尖頭流量과의 單純相關分析 結果 相關係數 r=0.004∼0.546으로 比較的 낮게 나타나 流域으로부터의 流出現像은 그 流域이 여러 因子에 影響을 받는다는 것을 確認할 수 있었다. 3. 流域面積, 主河川長, 主河川 平均傾斜, 貯水池 設置點의 標高를 獨立變數로 하여 尖頭流量과의 多衆相關分析을 實施한 結果 ??인 相關式이 誘導되었다. The purpose of this study is to develop regression equations between peak flow and physical charateristic factors of watersheds. 112 irrigation reservoirs located in South Korea which are equal or larger than 200 has. in the irrigation area, are used in the analysis of this study. The results obtained from this study are as follows. 1. The results of correlation analysis of the relationships among the characteristic factors of the watersheds have been derived high significances. 2. Relationship between the peak flow and the simple correlation analysis of physical characteristic factors of the watersheds has been derived low significance. 3. The result of the multiple regression analysis between the peak flow and four physical characteristic factors of watershed such as watershed area, main stream length, average slope of main stream and elevation of reservoir are shown as the equation ; ??.(r=0.838)
