Buffer zones of riparian vegetation and areas with hydrophilic treatment plants for protecting water bodies from pollution

By

The measures describe vegetation-covered systems which are in varying degrees saturated with water. They pre-treat rainwater and extend the retention time. They can serve as buffer zones around water bodies. Pollutants are removed as a result of intensive sedimentation and assimilation by aquatic vegetation and adsorption in biogeochemical barriers e.g. in the form of gabions…

Restoration of floodplains and floodplain forests, natural succession

By

Identifying and re-establishing of flood plains and deposition areas, such as by removal of protection structures for agricultural land, contributes to the retention of water along rivers and, thus, to heavy rain risk reduction. In the past, most floodplains have been taken over for other uses; former floodplain forests are separated from river and runoff…

Catchment based concepts and plans; inter-communal cooperation

By

Land use and land cover changes as well as intensification or extensification of land use are altering the hydrologic system and have potentially large impacts on flooding in lower lying areas. Upstream and downstream interconnections, interactions and action’s intereffects should be taken into consideration in planning activities, especially when problems occur in settlement areas. Formal…

Restoration of wetlands

By

Among other benefits, the measure serves as a heavy rain risk reduction measure as it delays and attenuates also water on its way to a stream. Wetland provides water retention and improves the hydrological regime of degraded land. Rewetting includes a wide variety of large and small-scale measures, e.g. impounding measures like blocking of drainage…

Risk area identification, mapping and designation

By

A proper hazard and risk assessment (with informative maps as central outputs) is the essential basis for starting an integrated risk management process. The assessment is a challenging multistep task, which requires – aside from clear objectives – input data (e.g. about historic events and damages, terrain and landuse data), methodological skills and decisions as…
