Decision support system for flood risk analysis for the River Thames, United Kingdom

The development of a decision support system for flood plain risk assessment and its applications and benefits are examined. The paper focuses on an application in the insurance industry and describes the use of airborne Interferometric Synthetic Aperture Radar (IFSAR) map products data in the development of a large-scale flood risk assessment system for the River Thames in the United Kingdom. Airborne radar technology ct as originally developed for military applications. In recent years, applications in telecommunications, oil exploration, and agriculture have proven that radar technology can also be used commercially. The innovative use of digital elevation model (DEMS) and orthorectified radar image (ORI) map products derived from IFSAR for flood risk assessment is discussed in the context of other risk assessment methodologies and techniques. The wider applications of this technology are considered for any organization exposed to flood risk.
