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…
Sand and bedload traps are technical installations which are located instream or as bypass to water courses. In the event of flooding, they slow down the speed of the water and lead to controlled sedimentation of transported material. To prevent debris and timber from blocking water courses in forests and on agricultural land, wooden or…
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…
Risk awareness grows and turns into action when recurring and continuous information and personal expert advice are provided to private home owners as well as to public bodies. Contact persons and public consultation hours offer a greater guarantee of success than online information services or advertising campaigns. Acceptance of measures can be additionally promoted if…
Such systems consist of a variety of a hydrophyte treatment plants for eco-hydrological regulation. They are structured in three zones: a zone for intensive sedimentation (in which a combination of fixed and portable structures modifies the hydrodynamics of the chamber and increases sedimentation); another zone for intensive biogeochemical processes (where thick limestone fractions capture phosphorus…
Heavy rain risk can significantly be reduced by converting farmland into grassland/deciduous forests or short rotation plantations. The measure increases the surface roughness constantly (effect: reduction of flow velocities) and decreases soil erosion (effect: reduction of mud deposition). The measure is well-suited for steep slopes with light soils, for runoff-pathways, for fields prone to flooding,…
