　　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，本年度主要工作項目包括（1）支援環保署審查開發行為環境影響評估個案之河川水質模式模擬結果；（2）整合提供環境影響評估河川水質評估模式技術所須背景輸入或參數資料；（3）評估水質模式對重金屬及新興污染物模擬能力及限制及（4）辦理經驗交流會議。本年度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7件、QUAL2K水質模式3件、HSPF/BASINS水質模式2件及8件其他。本年度環評案件追蹤審查案件已有15案件，協助參與出席範疇界定會議2個案件，蒐集鳳山溪（採用HSPF/BASINS）、乾華溪、大安溪及新街溪（採用QUAL2K）水質模式模擬應用案例，彙整背景輸入及參數資料。經分析環境影響評估河川水質評估模式技術規範認可之水質模式可模擬與預測河川重金屬，新興污染物非法規或地面水體分類及標準項目，因無足夠水質資料，故水質模式無法模擬與預測水體新興污染物。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、納入河川水質模擬評估於範疇界定會議項目、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，以提供水質模擬所需之背景資料，降低評估單位資料蒐集負荷及增進環評案件評估效益。

The purpose of this study is to assist Taiwan EPA in reviewing the report of environmental impact assessment (EIA) on the section of 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 the surface water quality. The tasks include: (a) reviewing at least 20 EIA reports, (b) assessing the applicability and limitations of the water quality models on the heavy metal and the simulation of emerging contaminants, (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 the water quality modeling. The study has adopted the water quality models (e.g. HSPF/BASINS, QUAL2K, and Mass Balance Method) listed in the guidelines of the water quality modeling to evaluate twenty EIA cases during this study. Five of them were assessed by the complex models (HSPF/BASINS and QUAL2K), seven by the Mass Balance Method, but eight were not assessed by any models. Fifteen EIA cases were followed up, and comments of the two EIA case were provided 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 the EIA cases. The results indicate that the HSPF/BASINS, SWMM, and WASP can be applied to heavy metal simulation and obtaining comparable results under well fit of the process of calibration and confirmation. However, the models can not be empolyed in the simulation of emerging contaminants in the EIA cases. The parameters of the four models are summarized for future application. During this study, the parameters of the two models were collected based on the EIA cases. For the HSPF/BASINS, the parameters of the Feng-shan Creek are collected. For the QUAL2K, the Cian-hua Creek, Da-an River, and Hsin-Jie Creek are 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. Guidelines for model assessment should be further developed.
