Management of Data Streams for a Real Time Flood Simulation

We examine the challenge of coupling applications to real-time data sources in a Grid environment. Such problems are important to the emerging field of Grid-based emergency planning and crisis response, in which realtime data sources must be coupled to modeling applications to provide timely forecasting to emergency planners and responders. In this paper we present a Grid-based scripting workflow system that is capable of managing both streaming data sources and service-based applications. We apply this system to flood modeling codes coupled to simulated NEXRAD Doppler Radar data.
