Tool risk reduction measures


Implementation and usage of early warning systems incl. collection and assessment of supplementing information

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.

Fields of action
Buildings, Emergency management, Settlement areas
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
