Abstract
 A Flood Forecasting System Integrating Web, GIS and Modeling Technology Track: Water Resources Author(s): Michael Butts, Anders Klinting, Martin Ivan, Jacob Larsen, Jørgen Brandt, David Price Effective operational flood forecasting systems must provide the right information at the right time to decision makers responsible for initiating flood response measures and issuing flood warnings. Key information includes the current river levels, meteorological observations and conditions, rainfall estimates (for example, from weather radar and satellites), as well as quantitative precipitation and hydrological forecasts together with their uncertainty. To address these requirements a highly accessible internet-based flood decision support system has been developed within the EU project FLOODRELIEF. Designed together with operational forecasters, this system provides information in a flexible, efficient and easily understood manner to operational users and decision makers. Using Esri technology, GIS-based maps are used to provide intuitive displays of the flood status and meteorological observations including weather radar and numerical weather forecasts. This decision support system is applied to regional flood forecasting in the FLOODRELIEF study catchment, the Welland and Glen, United Kingdom.
