首先基于ArcGIS Engine建立小区水容积-水位关系;进而对暴雨过程线公式进行推导,并建立暴雨水调蓄模型;最后利用暴雨水调蓄模型建立径流流量、排水流量随时间变化关系图,并基于ArcGIS Engine实现暴雨水调蓄模型的三维分析系统。
Firstly, the relationship between water volume and water level in residential area was established based on ArcGIS Engine. Then the formula of rainstorm process line was deduced and the stormwater storage and storage model was established. Finally, the stormwater storage model was used to establish the relation diagram of runoff and drainage flow with time, Three Dimensional Analysis System of ArcGIS Engine to Realize Stormwater Regulation and Storage Model.
