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.

This measure is usually carried out in form of sets of barrages built in a direction perpendicular to a stream’s direction. The aim of the measure is to modify the erosion and accumulation processes in torrent streams through the retention of water and eroded material, e.g. when settlement areas are at risk. It effect is enhanced when applied together with other measures in the watershed. The material used for the barriers depends on the natural conditions of the area of interest and on hydro-technical calculations. Permission by water management authority and nature conservation authority may be required.

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.
