Abstract

A two-dimensional flow and sediment routing model in flood diversion and storage area was established based on Google Earth software. According to DEM (Digital Elevation Model), the grid terrain elevation was easily obtained by model interpolation module, and the model pre-treatment was rapid and efficient. The model calculation was carried out by finite volume method which keeps water and momentum conservation even with very coarse grid. The post-treatment module was developed based on Google Earth software by which virtual dynamic simulation can be implemented. The calculated flow field can be embedded into the 3-D aerial landscape in Google Earth software. The model system was applied to the flood diversion and storage area of Jingjiang river. It is very suitable for the rapid calculation in emergency conditions, and the calculation results provide reference for flood control and emergency rescue in flood diversion area.
