Executive Summary

Web-based Geographic Information Systems (WbGIS) provides key decision support capabilities for the disaster and emergency management community. Perspective visualization and simultaneous access to emergency management data are important capabilities that WebGIS can provide in support of informed decision-making process. By using a case study on a section of the Don Valley in Toronto, Canada, this paper will present a WebGIS based interdisciplinary approach for flood risk assessment and will demonstrate the utility of WebGIS in simulating different what-if scenarios under different water surface elevations.
