本計畫係為全台灣地區地下水及伏流水資源調查工作之先期計畫，將綜整既有文獻及研究成果，就地下水及伏流水資源開發所應具備之前期資訊建立規範，提出因地制宜之作業流程，以作為後續台灣地區(含台灣北段山區及離島)地下水及伏流水資源調查規劃工作推動之參據。

This project focuses on the preliminary work of the investigation plan for groundwater and hyporheic flow resources. After collecting the related references and the results of previous studies, the specifications of the data for evaluating groundwater and hyporheic flow resources were established. What is more, the achievement of this research is the guide for future investigations and assessments of groundwater and hyporheic resources in Taiwan. According to the references of groundwater and hyporheic flow resources investigations, the most important work of each investigation is the hydrogeological surveys and the tests. The results of the hydrogeological surveys and the tests can be used to establish a hydrogeology conceptual model for evaluation and further discussion in the future. Furthermore, the effect of the river discharge could be the criterion of the assessment process of groundwater and hyporheic flow resources development potential. The Reference Manual of Investigation and Analysis for Available Yield of Groundwater Zones in Taiwan is an important output of this research. The process of the typical groundwater investigation includes four levels; data collection and analysis, field investigations and tests, hydrogeological conceptual model, numerical simulation and estimation of acceptable yield. In this project, 44 reports for 9 major groundwater zones are introduced. The basic hydrogeological characteristics of these groundwater zones are presented in details. According to the hydrogeological characteristics and the due to lack of the basic data, the works of future investigation of each groundwater zone is set in the Plan of Investigation and Analysis for Available Yield of Groundwater Zones in Taiwan. The duration of the overall plan will be from 2017 to 2024. Total funding requirement is NT 121,500,000. Another important output is the Reference Manual of Investigation and Plan for Hyporheic Flow in Taiwan, which categorizes the process of the hyporheic flow resources to three scales; basin scale, reach scale and site scale. The results of each hyporheic flow resources investigation plan can assess the potential of hyporheic flow resources in a specific site. Additionally, the preliminary study investigates the assessment of groundwater resources in the North Mountain Area in Taiwan by using the existed data which are also included in this project. There are 2 regions with high groundwater resources potential. Last but not least, the groundwater observation networks of offshore islands in Taiwan, is evaluated as well. The total of the observation wells of the islands of Penhu, Kinmen, Matsu and Green Island are 4, 3, 4 and 1 respectively.

這份報告是臺灣地下水區可用水量調查分析及伏流水調查規劃的先期作業成果。計畫旨在建立一套標準化的地下水與伏流水資源調查方法與規範，以供未來研究參考。 報告內容包含： * **文獻回顧與案例分析：** 蒐集國內外相關研究，了解現有的地下水與伏流水資源評估方法，並分析其優缺點。 * **臺灣地下水區現況分析：** 彙整臺灣九大地下水區的文獻資料，分析其水文地質特性、地下水補注狀況及超限利用情況。 * **調查手冊規劃：** 研擬「臺灣地下水區可用水量調查分析參考手冊」及「臺灣地區伏流水調查規劃參考手冊」，詳細說明資料需求、調查方法、概念模型建置、數值模擬及可用水量估計等。 * **調查計畫規劃：** 提出「臺灣地下水區可用水量調查分析計畫草案」，規劃各地下水區的調查優先順序、期程、經費及執行方式。 * **初步調查研究：** 針對臺灣北段山區進行初步的地下水資源開發潛能評估，並規劃離島地區（金門、馬祖、澎湖、綠島）的地下水觀測站網。 本計畫的目標是建立科學可靠的地下水與伏流水可用水量數據，以作為未來水資源管理與開發規劃的基礎，進而提升臺灣水資源供應的穩定性與永續利用。
