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.

Permeable paving is designed to allow rainwater to infiltrate through the surface, either into underlying layers (soils and aquifers), or be stored below ground and released at a controlled rate to surface water. Sealed surfaces can be replaced by different materials, such as gravel turf, grass pavers, concrete pavers with drainage or porous concrete. This is suitable for parking lots, cycling paths, walking paths and access roads, terraces and yards.

Fields of action Buildings,Settlement areas,Farmland,Forests
Additionally to flood risk reduction by storing surface runoff, the measure has medium or high possible benefits for the following biophysical impacts and ecosystem services: Increase infiltration and/or groundwater recharge; Filtration of pollutants; Intercept pollution pathways; Reduce erosion and/or sediment delivery
