100 KOCKÁZAT CSÖKKENTŐ INTÉZKEDÉS

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.

Rain gardens are small-scale vegetated gardens used for storage and infiltration. They are typically applied at a property level and close to buildings, for example to capture and infiltrate roof drainage. They use a range of components, typically incorporated into the garden landscape design as appropriate. Under the vegetation layer is a filter bed substrate located for absoption of infiltating water.

Fields of action Settlement areas,Buildings
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: Increase evapotranspiration; Increase infiltration and/or groundwater recharge; Create terrestrial habitats; Biodiversity preservation; Climate change adaptation and mitigation; Filtration of pollutants; Recreational opportunities; Aesthetic/cultural value; Intercept pollution pathways; Reduce erosion and/or sediment delivery; Reduce peak temperature
