Conversion to Extensive Grass Land for Flood Risk Management
Courtesy of IWA Publishing
The Mitigation Strategy of the measure Conversion to Extensive Grassland refers to flood prevention and environmental protection also.
Flood protection can be achieved by:
- Increase the infiltration of rainwater by high roughness and preventing soil silting,
- Reducing the flow velocity of surface run off,
- The hydrologic-hydraulic effect varies depending on the vegetation, soil condition at the time of conversion (compression, water conductivity) and the season.
Environmental protection by:
- Improve habitat and biotope networking function for plant and animal species characteristic of open land (particularly potential grassland bird-nesting areas, bird resting places),
- Protection of the soil from water erosion,
- Groundwater protection trough reduction of nitrate leachate,
- Appreciation of the landscape and increase the effectiveness of the experience of landscape (depending on the grassland proportion of the landscape).
