中文摘要

在水利工程規劃與洪災預警中常利用水文水理模式進行數值模擬,因此水文水理模式需要足夠與可靠現場資料進行參數檢定驗證,以確保模擬結果能正確反應現場水理現象,然而臺灣地區之區域排水的水路系統常常極為複雜且水工構造物眾多,無法透過現今慣用之模式參數建議值來正確顯現,為達到提升數值模式模擬結果的精確度,首先選定地文特性較為單純之區排流域,透過現地水文觀測資料,以進行水文水理數值模式參數本土化之推求與探討。本研究於2019年選定八股排水系統開始進行長期水文觀測,於集水區內設置2處雨量站、18處水位站、6處水位與表面流速站,至今已獲得歷年多場次暴雨與颱風之雨量與水位完整觀測資料。另外利用SOBEK水理模式之降雨逕流模組與一維水理模組,透過完整的長期觀測資料,提供模式參數檢定驗證依據,並經由檢定驗證程序以最佳化方法,針對八股排水集水區內不同土地利用型態之本土化逕流曲線係數CN值進行推求與探討。

英文摘要

In hydraulic engineering planning and flood early warning, hydrological and hydraulic models are often used for numerical simulation. Therefore, the hydrological and hydraulic models need sufficient and reliable field data for parameter calibration and verification to ensure that the simulation results can correctly reflect the on-site hydraulic phenomena. However, the drainage systems in Taiwan are often extremely complex and there are many hydraulic structures, which cannot be correctly displayed through the current customary suggested values of model parameters. In order to improve the accuracy of the simulation results of the numerical model, we first select a drainage basin with relatively simple geography characteristics and use the on-site hydrological observation data to discuss the localization of the parameter values of the hydrology and hydraulics model. In 2019, the Bagu drainage system was selected for long-term hydrological monitoring in this study. Two rainfall stations, 18 water level stations, and six water level and surface velocity stations were set up in the catchment area. So far, the observation data with rainfall and water level of many rainstorms and typhoons over the years has been obtained. In addition, the rainfall-runoff module and the one-dimensional channel flow module of the SOBEK hydrodynamic model are used to provide the basis for calibration and verification of model parameters through complete long-term observation data. And through the calibration and verification procedure, the optimization method is used to calculate and discuss the localized curve number of different land use types in the Bagu drainage catchment area.
