摘要: 中文摘要 眾所周知,流域為水文分析及集水區整治之完整單元。本研究乃採用台灣省政府水利處現有之149個雨量測站,其記錄年期迄1997年為止,各歷年之10、20、30、40、60、90、120、180、240、360、720、1080、1440分鐘等13種延時之降雨資料,以年最大值選用法,進行相關統計分佈測試,其包括常態分佈、對數常態分佈、極端值Ⅰ型分佈、對數皮爾遜Ⅲ型分佈等四種理論分佈,並利用卡方檢定法,進行不同機率分佈之適合性檢定以尋求其最具代表性及適合性之機率分佈,進而推求不同頻率年之降雨強度,再推導河川流域降雨強度-延時-頻率關係式,提供一流域為主之雨型分析模式。同時,本研究應用地理資訊系統軟體ARC/INFO及ArcView3.0,配合地理資料庫的建立與自行撰寫之物件導向程式,建置一套架構於ArcView系統上,完整之流域水文雨型分析。
ABSTRACT In general, watershed is the basic unit for hydrologic analysis as well as river system management. This study uses recorded annual maximum rainfall data for various rainfall duration of 149 gauge stations in Taiwan area to first determine its probability distribution type based on normal, log-normal, log-Pearson type III and Gumbel extreme-value distributions and tested by X goodness of fit. After that, a series of design rainfall intensity-duration-frequency (IDF) relation for all gauge sites can be expressed through numerical regression. Also, by Thiessen's weighting processing, the IDF curves for 19 main watersheds within Taiwan area are formulated. In addition, the proposed study is constructed upon ArcView geographic information system computer software, which is much more powerful in linking geo-science and watershed science application. Thus, it would certainly make hydrologic analysis easier for design engineers. Finally, through the comparison with the results obtained by Water Resources Bureau of Taiwan Provincial Government, it is concluded that the proposed study is more helpful in rainfall intensity design for watershed concerns.
