Transcription

1 RIMAX Research on Managing Risks of Extreme Flood Events Research programme of the German Federal Ministry for Education and Research (BMBF) IFAT Munich, 8 May 2008 Ruth Bittner, Bruno Merz, Knut Günther funded by project management organisation coordination

2 BMBF National Research Programme RIMAX Risk Management of Extreme Flood Events Aim To develop and implement improved instruments of flood risk management Main focus and transfer from flood defence to flood risk management extreme events with: return period > 100 years high destructive potential transdisciplinary approach Involved 38 (cooperation-)projects, more than 100 partners 65% science 20% small companies 15% administration Coordination GeoForschungsZentrum Potsdam (GFZ), Section 5.4: Engineering Hydrology in cooperation with CEDIM - University Karlsruhe funded by project management organisation coordination

3 Major Subjects of RIMAX Analysis, Forecasting, Warning Operational flood management Forecasting and early warning Analysis of historical floods Transdisciplinary analysis of extreme flood events and their consequences Risk-based approaches to flood mitigation Protection and Control Dyke safety, monitoring and dyke protection Management of dams and retention systems Management of urban infrastructure (water supply, ppy, sewage etc.) during floods Risk-based reliability analysis of flood defence system B. Westrich R. Glaser Information and Communication Education Networking Flood awareness Risk communication FLOODmaster, Jörg Seegert

4 Products from RIMAX Highly specialized flood models Rainfall and flood forecasting models Decision Support Systems Systems for operating dams and reservoirs Methods for risk analysis Evaluation and development of monitoring systems for dykes Innovative and cost-saving technologies for dyke restoration Databases Handbooks and guidelines Risk communication, e. g. exhibition, international teaching module

9 Products - examples Innovative non-technical measures for flood protection Retention Capacity of River Networks Retention efficiency of flood plains middle and small rivers Retention ti capacity of flood plains can be activated by appropriate measures for river development Estimation of retention capacity of rivers by available data, e. g. land use, DEM, structural quality of waters Classification of retention capacity: K [min] Klasse Farbe 0 6,62 Kaum 6,62 9,25 Gering 9,25 13,36 Mäßig 13,36 19,7 Mittel 19,7 29,69 Hoch Essential contribution to flood 29,69 55,29 sehr protection 55,29 200,67 hoch extrem hoch

10 Products - examples Risk communication and enhancement of flood awareness Cost-saving measures for improvement of flood risk management: Integration of demands on human resources and required equipment into the concepts for flood protection Standardization of flood prediction Improvement of coordination and flood precaution in a whole catchment (across political borders) Improvement of public relations and risk awareness in the public Cycle of flood risk management
