Study on GIS-Based Flood Routing Dynamic Visual Simulation

With geographic information system (GIS) and three-dimensional simulation graphics technique, the technical principles and methods of GIS-based flood routing dynamic visual simulation for river, storage and detention basins are discussed in the paper. At the same time, the process of establishment of three-dimensional visual models is analyzed, and the general framework and development pattern of the flood routing system for river, storage and detention basins is designed. In the end the realization of functions of the system is also introduced in details. The application of the simulation system in a practical case shows the effectiveness of the presented technique, and it can provide quick and intuitionist dynamic information support for flood control decision-making.
