中文摘要 | 本研究應用美國水土保持周的SCS曲線值法,對集水區內之土地利用、土壤種類與植生覆蓋密度等條件予以掌控,經地理資訊系統(GIS)之整合,推求出翡翠水庫集水區各雨量站控制面積之SCS曲線值,並就春、夏、秋、冬四個季節分別建上季節性之逕流係數,由結果明顯呈現出夏秋因受西南氣流及颱風之影響而使逕流係數較大,而冬季則因台灣北部地區受東北季風之影響,逕流係數值也偏高。 |
英文摘要 | This study used curve number approach ofU.S. Soil Conservation Service (SCS) for quantifyingthe influences of land use, the water content of soil, and the density of vegetation cover on watershedhydrology. After combining with GIS, the SCS curve number for every controlling area of each rainstation, and runoff coefficient of four seasons in the Feitsui reservoir watershed were determined.The results reveal that the runoff coefficient is very high in summer and fall because the rainfall wascaused in West-South monsoon and typhoon. To the East-North monsoon in north of Taiwan; therunoff coefficient in winter is higher than any other places in Taiwan. |
