| Zusammenfassung |
| Flood risk analysis and management plans mostly neglect groundwater
flooding, i.e. high groundwater levels. However, rising groundwater may
cause considerable damage to buildings and infrastructure. To improve the
knowledge about groundwater flooding and support risk management, a survey
was undertaken in the city of Dresden (Saxony, Germany), resulting in 605
completed interviews with private households endangered by high groundwater
levels. The reported relatively low flood impact and damage of groundwater
floods in comparison with mixed floods was reflected by its scarce
perception: Hardly anybody thinks about the risk of groundwater flooding.
The interviewees thought that public authorities and not themselves, should
be mainly responsible for preparedness and emergency response. Up to now,
people do not include groundwater risk in their decision processes on self
protection. The implementation of precautionary measures does not differ
between households with groundwater or with mixed flood experience. However,
less households undertake emergency measures when expecting a groundwater
flood only. The state of preparedness should be further improved via an
intensified risk communication about groundwater flooding by the
authorities. Conditions to reach the endangered population are good, since
70% of the interviewed people are willing to inform themselves about
groundwater floods. Recommendations for an improved risk communication are
given. |
