Abstract

Geographic Information Systems (GIS) are used to store, manipulate and visualize both spatial and non-spatial data. Because of their data manipulating capabilities, GIS have been recognized as a powerful tool to integrate and analyze data the context of flood management. To provide decision-relevant information supporting planning and management, GIS are integrated with hydrological models for scenario analysis and optimization tasks. However, with the aid of three-dimensional (3D) visualization technology, users can understand the spatial phenomenon deeply. This paper develops a system for regional scale flood prediction and protecting that integrates GIS, hydrological models, and 3D visualization. The well-known HEC models and self-develop models were used to compute flooded areas and estimation flood loss. The 3D virtual environment is accomplished by self-developed 3D graph engine. This approach provides a very useful tool, not only for flood policy formulation and floodplain management but also very appropriate for individual and institutional decision making processes.
