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.

Predefined flow routes aiming on diverting surface water away from building can be built on the property or along its boundaries, e.g. by a change in gradient, ground sills, creation of depressions or by building of water diverting structural elements like walls. Areas on the property such as basins or trenches may be constructed for collecting the water and providing a controlled infiltration into the soil. Definition of requirements by municipality is possible.

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.
