1,900 kilometres of flowing waters 50 flood reten- tion basins Flood Protection Flood Protection Upstream of Settlements 50 flood retention basins for the case of heavy rainfall Retention basin filled Flood Action Plans
Planned for each sub-catchment Prepared by WVER and other authorities Based on range of extreme flood event scenarios (5-, 10-, 20-, 100-, 200-year floods) Results: . Which areas will be flooded? . What damage expected at which locations? . What measures to prevent damage?
Benchmark: technical flood protection for a hundred year flood Flood Risk Plans
Also according to frequency of flooding:
Which areas will be flooded, what velocity of flood wave ? Which institutions and buildings are affected ? What hazard sources are there ?
Which roads can still be used ? Where are relief organisations situated ?
Important planning criteria for emergency services!
Flood Risk Plans Flooding with frequency of one hundred years (blue colour)
Extreme flooding (red colour) (occurs only once in a thousand years) Dams Excess surface run-off in the Eifel low mountain range Construction of first dam: the Urfttalsperre Dams Multifunctional use
