 Create zones for controlled flood retention

 Improve biological and ecological water quality Renaturation River Rur near Körrenzig

Surface Waters Maintenance of rivers and streams Surface waters

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

 Flood protection  Equalization of water run-off

 Storage of high-quality raw water for drinking water production

 Storage of raw water for industrial use

 Hydroelectric power generation

 Tourism / Recreation Dams

 6 multifunctional dams  Total capacity 300 million m³  70 million m³ flood protection storage space Dams
