摘要：In this paper, we present the development of a Web GIS based system for early warning and mapping for flood disasters. To improve flood warning, we developed a decision support system for flood prediction and monitoring that integrates hydrological modelling and GIS. We present the methodology for data integration, floodplain delineation, and online map interfaces. Our Web- based GIS model can dynamically display observed and predicted flood extents for decision makers and the general public. The users can access a Web-based GIS that models current flood events and displays satellite imagery and a digital elevation model integrated with the flood plain area. The system can show the flooding prediction based on the output from hydrological modeling for the next 24 and 48 hours along the lower Saint John River Valley
