摘要:
|
| 基于ADCIRC模型建立了徐聞高分辨率的風暴潮模型,并以1415號臺風"海鷗"路徑為基礎,通過路徑平移構建了一系列臺風路徑,模擬計算了徐聞沿海風暴增水。結果表明:徐聞東部沿岸的風暴增水最大,主要原因在于東部沿岸的獨特地形特征以及該區(qū)域受到的有利臺風路徑影響。在上述工作的基礎上,耦合海浪和天文潮的作用,計算10個不同等級下徐聞風暴潮淹沒情況,計算結果顯示,徐聞東部沿岸的風暴潮淹沒災害大于南部和西部沿岸。 |
| Based on ADCIRC model, a high-resolution model is established to simulate the coastal storm surge along the Xuwen using a series of typhoon tracks conducted through track translation of typhoon "Kalmaegi" (1415).The results show that the maximum storm surge is along the eastern coast of Xuwen, which is mainly due to the unique topography and the favorable typhoon tracks in the area. On the basis of the above work, the storm surge inundation conditions of Xuwen under 10 different levels of minimum air pressure are calculated by coupling the effect of ocean wave and astronomical tides, which reveals that the storm surge inundation disaster along the eastern coast of Xuwen is more serious than that along the southern and western coast. |
