确定洪水过程中的淹没区域,对洪水风险分析、灾情评估以及防洪减灾等意义重大。文章采用在给出已知的洪水水位值与洪量值这两种不同情况下的方法对洪水淹没过程进行分析,同时运用Arc GIS二次开发模拟洪水淹没过程,确定其淹没范围。结果显示,选择平面模拟方法来对洪水淹没范围进行模拟是可行的。
Determine the flooded area during the flood, flood risk analysis, disaster assessment and flood control and disaster mitigation is of great significance. In this paper, flood flooding process is analyzed under two different situations of known flood level and flooding value. At the same time, ArcGIS secondary development is used to simulate flood flooding process and determine its flooding range. The results show that it is feasible to choose the plane simulation method to simulate the flood inundation range.
