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.
Drainage ditches; swales
Ditches allow intercepting, infiltrating and alternatively draining the surface runoff without causing damage. They should be dimensioned to the corresponding return period of the discharge, meet functional requirements and get regular control and maintenance. Ditches on farmland are usually proposed in areas where the space for constructing furrows is limited. Within urban areas they are part of the urban drainage system and can have a variety of cross sections to suit the urban landscape. They can include the use of planting to provide enhanced visual appeal and water treatment. The measure requires an occupation of land. Therefore, settlement of property rights relations is necessary.
