台灣部分海岸地區屬於高風險災害地區，面臨氣候變遷所引致之海平面上升以及極端水文事件，對於海岸地區都市與聚落為嚴重地層下陷地區之高風險災害地區造成極大衝擊。本研究以整合性海岸之角度，探討海岸地區都市與聚落面臨地層下陷之海岸災害及其他氣候變遷引致之複合型災害影響，針對海岸地區都市與聚落地層下陷受災風險潛勢進行評估分析，以達海岸地區都市與聚落土地利用規劃永續發展之長期經營目標。本研究計畫進行「海岸地區基礎環境資料與風險評估研究方法建置」，針對海岸地區基礎環境資料，建置地下水特性與地層下陷評估之數值分析模式與受災風險評估研究方法，研究過程中進行「海岸地區地層下陷受災風險潛勢評估分析」，以利後續進行「未來氣候變遷對於海岸地區維護管理與調適策略」，考量未來氣候變遷趨勢下，海岸地區都市與聚落推估型受災風險評估分析，以擬訂海岸地區都市與聚落維護管理與調適策略。 Global climate changes have increased the rate of global sea level rise in recent decades. In particular, the coastal areas as well as the islands have been dramatically affected due to the global climate change. Several kinds of coastal hazard such as storm surge, coastal erosion, flooding and land subsidence problems have suffered in Taiwan’s coastal areas. Therefore, the coastal areas in Taiwan have become high-risk areas. In the case of limited natural resources in Taiwan’s coastal areas, how to mitigate the land subsidence problem and to propose the future coastal management for coastal hazard prevention are crucial issues to ensure sustainable development of the natural environmental resources. A one-year project is carried out to deal with the key issues mentioned above. The project is to study the transient modeling of regional groundwater characteristics and land subsidence problems in the coastal areas. As a result, the land subsidence risk maps are expected to be created under different climate change scenarios. The results of this project may be a fundamental contribution to environmental effects for land subsidence problems in coastal areas with higher occurrence and risk. It is expected that results can be used to propose the elaboration of adaptation strategies as well as the sustainable development and the elaboration of adaptation strategies in Taiwan’s coastal areas.
