為提供本局台南及高雄海堤災害預測資訊，本局已於民國105年建置海堤作業化海岸防災資訊系統，展示海堤區域波潮演變與溢堤越波預測資訊。為持續校驗預測系統準確性，本局擬辦理海堤溯升預警系統維護計畫，主要工作內容乃持續更新轄管台南及高雄近岸地形水深變化及海堤幾何斷面相關資料，作為觀測儀器架設與溯升估算的背景資料，根據國際公認氣象組織所發布之海氣象條件，模擬台灣沿海波潮變化，作業化產出台南及高雄海堤區域的波潮資訊，同時應用國際常見海岸工程手冊，估算台南及高雄海堤在颱風侵台期間的最大溯升高度，並於颱風期間現場配合堤面溯升量測系統，觀察相對應最大溯升高度以檢視溯升演變之正確性。透過視窗網頁作業化展示，於台南及高雄海堤颱風侵台期間海堤區域波潮資訊、堤面溯升高度預測結果，作為本局未來規劃海岸防災治理之參考。

To provide the Sixth River Management Office, WRA the run-up and overtopping prediction information along the seawall in Tainan and Koahsiung city, this project maintains the seawall run-up early warning system. Numerical models are utilieze to predict the waves and tides and the highest run-up and the overtopping at 36 seawalls are estimated by using the formulas in the CEM (Coastal engineering manual) for the future 48 hours. Waves, tides, the run-up, and the overtopping information is displayed on the operational website for the hazard mitigation and the planning of shore protection. Fourthermroe, the hourly hightest run-up data are measured for validation the estimated run-up data.
