　　本計畫目的在協助支援環保署審查環境影響評估河川水質評估模式，主要工作項目包括（1）支援環保署審查環境影響評估個案之河川水質模式模擬結果；（2）提供範疇界定會議之河川水質項目書面意見，並派員參與範疇界定會議討論；（3）整合提供河川水質模式技術所須背景輸入及參數資料；（4）辦理經驗交流會議。計畫執行期間共支援環保署審查環評個案共39件，其中使用QUAL2K、WASP及HSPF/BASINS模式共有7件，質量平衡公式有11件及21件其他（包括以放流水標準、納入污水下水道、零排放等方式）。計畫執行期間追蹤審查環評個案計有25案，派員參與共8案之範疇界定會議。蒐集環評個案之河川參數資料如下：（1）HSPF：和平溪、南澳溪、金瓜寮溪、逮魚崛溪、北勢溪、大漢溪、頭前溪、鳳山溪；（2）SWMM：翡翠水庫集水區、頭前溪、大甲溪、大埔美溪；（3）QUAL2K：新店溪、鳳山溪、頭前溪、淡水河、大漢溪、和平溪、鹽水溪（大洲排水）、番仔寮排水；（4）WASP：急水溪、淡水河、烏溪，各河川之參數。後續建議持續辦理支援環保署審查河川水質模式模擬結果、持續追蹤審查、建議河川水質模式模擬納入範疇界定會議討論、辦理經驗交流會、背景輸入與集水區特性應持續收集及整合，以提供河川水質模式模擬所需之背景資料，降低背景資料輸入收集負荷及增進環評個案評估效益。

　　The purpose of this study is to assist Taiwan EPA in reviewing the report of environmental impact assessment (EIA) on the section of receiving water quality modeling. Four main tasks are conducted to provide technological support in examining the results of Water Quality Modeling which is used in the assessment of surface water quality. The tasks include: (a) reviewing at least 20 EIA reports, (b) providing comments on scoping meeting, (c) evaluating the performance of the four models (HSPF/BASINS, SWMM, WASP, and Qual2k) which were applied in EIA cases and summarizing the results of modeling application, and (d) holding a workshop to discuss Water Quality Modeling. In 2015, the water quality models (e.g. HSPF/BASINS, SWMM, WASP, Qual2k, and mass balance method) listed in the guidelines of Water Quality Modeling are used in project development as EIA report process. Seven EIA cases assessed by the complex models (HSPF/BASINS, WASP and Qual2k), 11 EIA cases by mass balance method, but 21 cases assessed by no model. Twenty-five EIA cases were followed up and comments were provided for 8 EIA cases during the scoping meeting. 　　The water quality models (HSPF/BASINS, SWMM, WASP, and Qual2k) are evaluated for their capability and applicability to the application of EIA cases. The results indicate that simulation of the four models can obtain comparable results under well fit of the process of calibration and confirmation. The parameters are summarized for future application. During this study, the parameters of the four models were collected based on EIA cases. For HSPF/BASINS, the parameters of the following rivers (Heping creek, Nanao creek, Jin Gua Liao, Diyu creek, Beishi River, Dahan River, Touqian River, and Fengshan creek) are collected. For SWMM, those of the following rivers (Feitsui, Touchien creek, Tachia River, and Dapumei creek) are collected. For QUAL2K, the following rivers (Xindian creek, Fengshan creek, Touchien creek, Danshui River, Dahan River, Heping creek, and Yanshui River) are collected. For WASP, the following rivers (Chishui creek, Danshui River, and Wu River) are collected. 　　Finally, several suggestions may help for further investigation. This study recommends that government agencies should work with institute to revise the modeling guidelines or implement models for EIA case applications. Moreover, the institute could play a critical role in archiving models and data, maintaining and upgrading them for future applications. The modeling workshops should take place frequently to emphasize on modeler education. Guidelines for model assessment should be further developed.
