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.

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 compounds); and a third zone for biofiltration (for the removal of biogenic compounds using macrophytes). The zones are separated from each other by gabions from thick gravel, which additionally filter water.

Synergies may exist between heavy rain risk management measures and other development goals like environmental protection, health care, and economic performance. Harnessing them requires involvement of different actors, enforcement of exchange between you and them and holistic thinking.
