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.

Flood early warning systems – if existing for the area – provide information that allow the actuation of emergency action (e.g. set up of a command unit, observation of risk areas) prior to the event and before damages occur. However, reduction of losses is possible only if early warning information are interpreted and assessed correctly, if they are underpinned with a risk assessment and action plans considering different scenarios. The collection and supplementing information from different (also from local) sources may facilitate and qualify the assessment of the information by the responsible personnel.

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: Store river water; Slow river water; Increase infiltration and/or groundwater recharge; Reduce erosion and/or sediment delivery; Improve soils; Create riparian habitat; Create terrestrial habitats; Water storage; Fish stocks and recruiting; Natural biomass production; Biodiversity preservation; Recreational opportunities; Aesthetic/cultural value; Increase evapotranspiration; Increase soil water retention; Reduce pollutant sources; Intercept pollution pathways; Create aquatic habitat; Reduce peak temperature; Absorb and/or retain CO2; Filtration of pollutants
