Tool risk reduction measures

100 RISK REDUCTION MEASURES

Please note:

This catalogue contains 100 measures that can contribute to the mitigation of heavy rain risks. These measures are very diverse: they range from structural to non-structural measures and from small, easy-to-implement solutions to comprehensive conceptual approaches.

The catalogue was compiled from existing catalogues from all RAINMAN partner countries as well as from knowledge and experiences made in the project without claiming universal coverage and without having expert knowledge in each of the covered business areas. Sources for further information and good practice examples are provided for a large number of the included measures.

Use the selection feature to find measures that are applicable in the field of action that you are dealing with or search for key words you are looking for.

Please consider that heavy rain risk reduction measures work best, when they are strategically applied and cleverly combined under consideration of the local conditions. Go back to RISK REDUCTION MEASURES for further guidance.

The main goal of this group of measures is to enhance the transformational and accumulation effects of existing and re-developing floodplains by terrain modifications like lowering of banks, offset or demolition of flood protection dikes etc. This allows the water to flood the floodplain during the periods of increased discharges.

Fields of action Farmland,Forests,Watercourses
Additionally to flood risk reduction by slowing and storing surface runoff, the measure has medium or high possible benefits for the following biophysical impacts and ecosystem services: Reduce erosion and/or sediment delivery; Create aquatic habitat; Create riparian habitat; Natural biomass production; Biodiversity preservation; Filtration of pollutants; Recreational opportunities; Aesthetic/cultural value; Improve soils; Slow river water; Intercept pollution pathways; Increase evapotranspiration; Increase soil water retention
