Description: Das Projekt "Europaeisches Hochwasserwarnsystem" wird vom Umweltbundesamt gefördert und von Bundesanstalt für Gewässerkunde durchgeführt. Objective: Problems to be solved: National water authorities are normally able to provide flood warnings between one and four days in advance of flood events. These warnings are usually based on weather forecasts in combination with a knowledge of the actual hydrologic conditions in the river basins concerned. However, the emergency civil and water management agencies would benefit from an increase in lead-time, to effectively implement their plans in downstream areas. Therefore there exists a need for improved flood forecasting to extend the flood warning period. Improved flood forecasting should enable more effective evacuation of people from high risk areas or the controlled release of water from reservoirs in upstream areas to create temporary retention basins to reduce flood volumes and peaks. EFFS aims at developing a prototype of a 4-10 days in advance European flood forecasting system. This system aims at providing daily information on potential floods for the large rivers Rhine and Oder as well as flash floods in small basins. The framework of the system will allow incorporation of both detailed models for specific basins as well as a broad scale for entire Europe. Scientific objectives and approach: The overall objectives of EFFS are to employ currently available Medium-Range Weather Forecasts (4 - 10 days) to produce reliable flood warnings, beyond the current flood warning period of approximately 3 days. The project will design a Medium-Range Flood Forecasting System for Europe, that will produce flood warnings on the basis of the Medium Range Weather Forecasts. On the basis of the newly developed system, flood forecasts will be produced in regions where at present flood forecasts are unavailable. The scientific objectives include: 1) the development and application of downscaling techniques for weather forecasts that can be used in real-time operational flood warning systems over large areas; 2) the design of a framework that allows for the use of different rainfall-runoff flood models linked to the Medium-Range Weather Forecasts in order to provide Medium Range Flood Forecasts; 3) the investigation of the concept of an overall water balance hydrological model as a basis for regional rainfall-runoff flood modelling; 4) the investigate of the accuracy of the flood forecasts in space and time starting off from uncertainties in Medium Range Weather Forecasts and assess the error propagation through the system; 5) the finding of methods to incorporate uncertainties both from the weather forecasts as well as from the hydrologic models to be used in operational forecasts and use them as a decision factor as part of the actual flood forecast; 6) the investigation and recommendations concerning methods to disseminate the forecasts to whom they might concern, and to retrieve feedback from the users.
