氣候變遷將導致海水位上昇及颱風強度變大、中心氣壓降低和次數增加，低氣壓和強風則引發暴潮和海水位異常上昇，加上波浪能量往近岸移動，將導致嚴重的海岸侵蝕、波浪溯升和越波、海水倒灌和沿海低窪區域溢淹。本計畫利用 Hsu et al. (2000) 所研發之耦合模式—結合 POM (Princeton Ocean Modelling) 和 FEM (Finite Element Method) 計算颱風引致之暴潮位，同時配合台灣環島潮位站資料和衛星觀測資料，使用學理分析台灣海域長期水位變化。本計畫將應用情境分析模擬颱風侵襲之暴潮位，提供暴潮和海水位上昇資訊，提高海岸防災效率。 Because of the global climate change, the increase of sea level rise (SLR) and storm surge will become more significant than before. The frequency of occurrence and strength of typhoon events also increase following the impact of climate change. In this study, we aim to simulate storm surge caused by typhoon using different scenarios. The long-term sea-level data from in-situ measurements of tidal stations and satellite altimeter will be used to estimate SLR around Taiwan coastal area. The decoupled model of POM and FEM developed by Hsu et al. (1999) are implemented in the prediction of storm surge. The innovative research will provide valuable information for wave run up, overtopping and coastal protection.
