Storage Management and Flood Warning in Urban and non-urban Drainage based on Runoff Prediction

Intense rainfall events are a major cause of flooding problems in urban and non urban areas. They are due to increased sealing of areas resulting in high runoff volumes. Especially in urban areas and small catchments the time interval between rainfall event and flood peak can be very short. This paper describes the integrated hydraulic precipitation runoff modelling system STORM.Control using predicted rainfall data to manage urban water systems and/or whole water sheds. It gives the opportunity to integrate an alarm system for civil protection forces to react in short term and prevent relevant constructions from damages. Coupling virtual data and measured data enables the steering of storages in order to lower peak flows in sewers and water courses. The system is using the open SOS standard for data collection and delivering. A web based Viewer HydroWebView is enabling "real time viewing" of the data in the sewer and river system.
