中文摘要 | 本研究將以南投縣境濁水溪支流之水里溪集水區為研究對象,運用集水區總量管理模式來進行氣象模擬與水文校正工作,希望藉此協助集水區總量管理工作。由於台灣集水區相關基礎監測資料庫尚未建立,故進行總量模擬時缺少許多模式所需之基本資料,為了研究能順利進行,本研究使用總量管理模式下之WDMUtil工具進行氣象資料模擬,模擬項目包括逐時蒸發散量與逐時降雨量。在建立模式所需基本資料庫後,研究中首先針對水文因子進行校正,校正之結果證實調整模式中AGWRC、LZSN、UZSN等3個變數有助於提升模式模擬之精確度。至於最後模式模擬之總逕流量誤差為10%,尚在模式標準之內;而50%最低流量與季節流量等2個指標則誤差過大,需進一步研究探討。 |
英文摘要 | This study used the TMDL model to complete weather simulation and hydrology calibration in the Shuili-stream watershed of Naotou County, Taiwan. We hoped the results could help the total maximum daily load (TMDL) management in the watershed. Because Taiwan’s watershed database was not yet established, TMDL model was hardly used for lack of many basic data. In order to simulate the TMDL successfully, we used the WDMUtil program in TMDL model to simulate weather data including hourly evapotranspiration and rainfall. After building the database, we calibrated the hydrological factors of model first. The results showed that we could calibrate three parameters of AGWRC, LZSN, UZSN in the model to improve the simulation accuracy. Finally, model simulation exhibited 10% errors in the total runoff volumes which were still acceptable according to the model standards. But the errors in 50% lowest flows and seasonal flows were too large, and should be improved further. |
