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.
