沿海區域是各國經濟社會發展最迅速的地區，也是世界人口最集中的地區，約佔全世界60% 以上的人口生活在海岸地區。且海平面上升，加強了近岸水動力作用，使海岸侵蝕加劇或原本遭遇的問題更加複雜。且近年來海岸地區複合式自然災害頻傳，颱風、暴雨，暴潮強度加劇及伴隨發生是海平面上升的另一個災害。IPCC AR5研究報告指出，氣溫上升將會導致颱風強度的增加，而颱風路徑通過沿海地區的暴潮災害發生頻率亦將提高，海平面升高無疑會抬升暴潮位，本來不易受襲擊的地區，有可能受到波及。因此，為了台灣海岸地區的永續發展，實有必要針對上述問題進行研究。故本計晝係以全流域整體觀點以河道、河口及海岸區域進行考慮水動力及漂沙與地形變遷交互作用的河口海岸地區地形變遷模式為基礎，配合環境變遷下區域海平面上升研究、地下水位及鹽化研究，進行整合型量化風險評估QRA(quantitative risk assessment)分析，及環境變遷下台灣「自然海岸」與「防災海岸」合宜的增減發展與防災策略整合型研究，並進而提出調適對策，提供政府永續發展政策規劃及12年國教海洋環境教育教材之參考。 Coastal areas are not only the fastest growing countries in economic and social development of the region, but also the most heavily populated areas in the world, accounting for over 60 percent of the world's population lives in coastal areas. Sea-level rise, coastal hydrodynamics strengthened the role of the coastal erosion problem exacerbated or otherwise suffered more complicated. In recent years, the coastal areas of composite frequent natural disasters, exacerbated by typhoons, torrential rain, storm surge intensity and rising sea levels associated with the occurrence of another disaster. IPCC AR5 report noted that rising temperatures will lead to increased typhoon intensity, but the typhoon path by storm surges will also increase the frequency of disaster occurrence in coastal areas, sea level rise will undoubtedly storm surge lifted position, the attack would have been less vulnerable areas, there may be affected. Therefore, in order to sustainable development of Taiwan's coastal areas, there is a need for research on these issues. So this project is based on a full river basin, with rivers, estuaries and coastal areas to consider hydrodynamic and sediments transport and topography changes the interaction of estuarine and coastal areas based on the model. The Regional Environmental Change with sea levels rising, the groundwater and salinization, conducted integrated quantitative risk assessment (QRA) analysis, and environmental changes around Taiwan's "Nature Coastline" and "Artificial Coastline" expedient changes in development Disaster Prevention strategy and integrated studies.
