中文摘要: 依据蓄满产流平衡原理,分析通城县2011年6月10日的致灾面雨量。以致灾面雨量、DEM数据为基础数据,利用GIS暴雨洪涝淹没模型,对通城县6月10日强降水造成的洪涝淹没水深、范围进行模拟,并利用实际灾情对模拟结果进行检验分析。结果表明,通城县全县均有不同程度的淹没,淹没区主要分布在沿河道两旁及地势低洼地区;淹没水深集中在0.5~2 m,占总淹没面积的35%,淹没模拟结果与实际灾情较为吻合。
Abstract:Hazard area of rainfall in Tongcheng County on June 10 2011 was analyzed according to runoff equilibrium theory. Flood inundated area was simulated by using GIS flood drowned model based on rainfall and DEM data, and the simulation results was tested and analyzed with the disaster results. The result shows that the whole county was inundated by different degrees, and the inundated areas focus in river and low lying areas. The depth inundated areas is between 0.5 and 2 m, accounting for 35% of all the inundated areas. The siumulated inundated area is similar to the actual situation.
