Urban River Underwater Terrain Modeling And Research

One of the most important channels for urban floodwater draining is its rivers. Lots of human waste, sewage water and polluted water form channel blockage for rivers to flow. This paper gives how to build a 3D model with precision for underwater topographic and realize the corresponding function which includes slope and aspect analysis, plotting profile, surface area, surface roughness and sediment of calculation. with data from both Hubing Pool in HFUT and Shiwuli Rever in HEfei City. Testing result shows it’s a good one.The issue has some practice significance for urban river manage and improving environment about urban river.
