本計畫目的在支援環保署審查環境影響評估河川水質模式，主要工作項目包括（1）支援機關審查開發行為環境影響評估個案或水污染防治及管理相關之地面水體水質模式模擬結果；（2）整合提供地面水體水質評估模式技術所須輸入及參數資料並擴編簡易操作手冊；（3）評析重金屬總量管制或加嚴標準河川之執行成效與研提污染削減策略及（4）辦理諮詢及技術交流會議。計畫執行期間已經支援環保署審查個案共20件，其中使用質量平衡公式有11件、QUAL2K水質模式1件、WASP水質模式3件及5件其他。製作頭前溪、和平溪（HSPF/BASINS）、大漢溪、大安溪與新街溪（QUAL2K）、烏溪、濁水溪、湳仔溝排水（WASP）及大埔美排水（SWMM）等9條河川水質模式簡易操作手冊，並蒐集今年度新增WASP河川水質模式三案例，位於客雅溪、阿公店溪及美福排水及1件新環評案件，以QUAL2K應用在大甲溪，背景輸入及參數資料。建置南崁溪流域及二仁溪重金屬模擬示範模式，並研析重金屬模擬污染削減策略情境之水質改善效果。辦理3場諮詢及技術交流會議，共121人次。後續建議應持續辦理支援環保署審查河川水質模式模擬結果、持續追蹤審查案件、持續收集及整合河川水質模式輸入參數，並推廣水質模式運用之廣度與深度。

The purpose of this study is to assist Taiwan Environmantal Protection Administration (EPA) in reviewing the environmental impact assessment (EIA) reports regarding the water quality modeling. Four main tasks are conducted to provide technological support in examining the results of water quality modeling which was used in the assessment of surface water quality. The tasks include: (a) reviewing at least 20 EIA reports, (b) summarizing the results of modeling application of the four models (HSPF/BASINS, SWMM, WASP, and QUAL2K) which were applied in the EIA cases, and a model user manual is prepared based on EIA cases, (c) developing a heavy metal TMDL, and (d) hosting workshops to discuss the water quality models. Twenty-two EIA cases were evaluated during this study. Two of the EIA cases were assessed by the QUAL2K, four by WASP model, eleven by the simple dilution model, but five were not assessed by any models. Two EIA cases were followed up, and comments on the EIA cases were provided during the scoping meeting. The WASP was applied to develop a heavy metal TMDL. The results showed that the Copper (Cu) must be reduced to meet the critical water quality under Q75 and Q50 low flow condition. The scenarios of Cu loading reductions were presented for the Cu TMDL developments in Nankan Creek and Erren Creek. Besides, the parameters of the water quality models are summarized for future application. During this study, the parameters of the four models were collected based on the EIA cases. For the HSPF/BASINS, the parameters of Toucian Creek, Heping Creek were collected. For the QUAL2K, Dahan Creek, Da-an Creek and Xinjie Creek was collected. For the WASP, Wu Creek, Juoshuei River and Nanzaigou drainage were collected. For the SWMM, Da Pu Mei drainage was collected. Finally, several suggestions for further investigation are provided. This study recommends that government agencies should work with institute to revise the modeling guidelines or model implementation for applications in EIA cases. Moreover, the co-working institute can 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.
