摘要

要高山集水區與都市集水區在降雨逕流的反應上有極大之差異，故對高山集水區之水文特性進行系列分析實屬必要。本研究以砂婆礑溪試驗集水區爲對象進行降雨逕流之模擬分析，所使用之方法爲洪水歷線電腦模式HEC-1中之克拉克單位歷線，史奈德單位歷線以及運動波模式法。模擬結果顯示，單場暴雨之模擬結果較連續暴雨爲佳，而克拉克單位歷線法爲最簡便又不失其準確性之模擬方法。

The response to rainfall and runoff in upstream watershed is more complicated than that in urban watershed; hence the hydrological characteristics of upstream watershed mlust be analyzed in detail. The purpose of this study is to model the rainfall run-off relationship in Sabo-dam Creek watershed by the three models, Clark unit hydrograph method, Snyder unit hydrograph method and kinematic wave method. The results show that all the three models used are more suitable for single rainfall event than for continuous event. The Clark unit hydrograph method, having simplify and providing acceptable accuracy is the best one in application.
