中文摘要 | 流量歷線圖係顯示集水區流量在時間上變化之關係圖,雨量歷線圖則係表示降水在時間上分佈之關係圖。由流量歷線圖並配合相應之雨量歷線圖即可反應出一集水區之地形與氣候特性,因此分析此二圖形間之關係往往被視為研究集水區水文特性之主要途徑。然而此一繪圖分析過程既複雜又費時,且坊間無針對此需要而設計之套裝軟體可資利用。本文介紹一套適用於IBM PC之電腦程式,能快速、精確地繪出流量及雨量歷線圖,並可分析降雨與逕流間有關之各個水文因子(包括有效降雨量、有效降雨延時、洪峰流量、稽延時間、總逕流量、總基流量、Φ指數、逕流係數等因子),以及推求1至6小時延時之單位歷線。此外,由於若干水文因子之值會因基流分離方法之不同而差異甚大,程式提供四種基流分離方法並於比較其差異。希望藉由此程式能對分析集水區各項水文因子有所助益。 |
英文摘要 | The study of the relationship between hydrograph and hyetograph is a key to understand the hydrologic characteristisc of a watershed. Unfortunately, drawing these graphs and analysis of their relation are complex and time consuming, and there is no suitable software available on market. For these reasons, a computer program for IBM or IBM compatible PC was developed. The program can be used not only to draw hydrograph and hyetograph accurately but also to calculate many hydrologic factors concerning rainfall-runoff relationship such as: effective rainfall, effective rainfall duration, lag time, baseflow volume, total runoff volume, peak discharge, Φindex and runoff coefficient etc. In addition, the program provides four methods for baseflow separation and can compute one- to six-hour unit hydrograph. It may be useful for hydrologic analysis and design. |
