【摘要】:利用ArcGIS對莆田沿海地區(qū)的地形、下墊面屬性和排水設施及排水運作方式進行預處理,建立臺風降水、風暴潮共同影響下的莆田沿海地區(qū)內澇模型。應用雷達估算降水及自動雨量站數據計算的熱帶氣旋"南瑪都"過程面雨量,以及此次暴雨過程沿岸海區(qū)和河口的時變水位作為模型的邊界條件,對莆田地區(qū)風暴潮災害風險進行評估試驗。針對2011年9月1日熱帶氣旋"南瑪都"造成的莆田沿海地區(qū)風暴潮及暴雨災害,利用暴雨內澇模型進行評估試驗研究,將模擬結果與實況災情進行對比,結果表明模型能夠較客觀地反映"南瑪都"過程降水和風暴潮共同作用的災害情況。
[Abstract]:The waterlogging model of Putian coastal area under the influence of typhoon precipitation and storm surge was established by using ArcGIS to pretreat the topography, underlying surface properties, drainage facilities and drainage operation mode of Putian coastal area. Using radar estimation of precipitation and automatic precipitation station data to calculate the tropical cyclone "Nanmato" process area rainfall, and the time-varying water level in coastal areas and estuaries during this rainstorm process, as the boundary conditions of the model. To evaluate the risk of storm surge disaster in Putian area. In view of storm surge and rainstorm disaster in Putian coastal area caused by tropical cyclone "Nama du" on September 1, 2011, using rainstorm waterlogging model to evaluate and study, the simulation results are compared with the actual disaster situation. The results show that the model can objectively reflect the disasters caused by precipitation and storm surge during the "Nanmato" process.
