本計畫以流域為範疇，檢討盤點各水系之水利署與其它單位相關政策、規劃與計畫，以自然洪水治理方式，納入如逕流分擔、在地滯洪及風險管理等策略，並扣合國土管理，以因應及削減氣候變遷與社會經濟發展可能產生之各面向風險，亦加強民眾實質參與，辦理河川、排水及海岸之流域整體風險改善與調適之整合規劃，同時考量水岸縫合與國土綠網之結合，希望能進一步形塑水文化與提升地方產業，產生水利產業之附加價值，以達到「中央管流域整體改善與調適計畫(110~115年)」所提之願景目標-「韌性承洪、水漾環境」。流域整體改善與調適計畫之定位屬政策指導型上位計畫，其規劃成果理應作為水利部門未來於頭前溪流域內各項施政計畫之依據。由此可見，流域調適規劃的實質目的，是將河川防洪減災治理之單目標，導向流域經營管理多元目標；藉由非工程或非傳統工程風險管理降低風險，進一步保障民眾福祉；藉由水岸縫合強化水利建設與民眾利害與共的社會文化鏈結，促進民眾愛護珍惜水利設施；藉由藍綠網絡保育，使水利建設兼顧動植物與生態環境保護而提升民眾福祉。在此目標下，爰辦理頭前溪流域整體改善與調適規劃，以達「中央管流域整體改善與調適計畫(110~115年)」提出之願景目標-「韌性承洪、水漾環境」。本計畫為2年度延續性計畫之第二年度計畫，上述說明也顯示，流域整體改善與調適計畫在性質上是「延續性」而非「跳躍性」，主要工作範疇仍應以河川分署權責為主，並協助涉及流域整體改善及調適相關工作之公部門共同協作，以有效推動流域整體改善及調適各項工作；惟流域整體改善與調適規劃難以全面性就各項改善與調適措施及策略的可行性及效益性進行深入探討，部分策略及措施之後續執行方向、作法與分工，仍需進一步規劃研究或協調。

Taiwan is facing the influences of global climate change which has caused frequent occurrence of extreme rainfall events. In considering the climate change and its risk management, the Water Resources Agency(WRA), Ministry of Economic Affairs has reviewed and inventoried relevant policies of WRA and other agencies, planning results and improvement plans using river basin as an unit. The review and inventory items include runoff allocation and on site flood detention to meet requirements of national land management, in addition, the enforcement of public participation and the combination of local river riparian and greening of national land are also considered to further shape up water culture and upgrade local industries for creating added value to the water industries for reaching the goal of "resilience to flood, beautiful water environment" as set in the "Overall Improvement and Adaptation Plan (2021-2026) for River Basins under the Jurisdiction of Central Government."The main purpose of this project is to improve the risks existed in the Touqian River basin and to plan adaptive measures against the challenging climate change for increasing overall resilience of national land and society. " To Improve" is to provide improving measures for insufficient existing risk managing capabilities or uncompleted risk management issues in the Touqian River basin. "To Adapt" is to plan relevant adaptive measures to increase resilience to flood for potential risks associated with climate charge in order to co-exist with risks including "watercourse risks", "land flood inundation", "conservation of blue-green networks" and "connecting riparian corridor". This project conducted an overall inventories related to the above mentioned four adaptive issues and provided relevant future visions for Touqian River basin.
