| Zusammenfassung |
| Flood risk assessment is an essential part of flood risk management. As part
of the new EU flood directive it is becoming increasingly more popular in
European flood policy. Particularly cities with a high concentration of
people and goods are vulnerable to floods. This paper introduces the
adaptation of a novel method of multicriteria flood risk assessment, that was
recently developed for the more rural Mulde river basin, to a city. The study
site is Leipzig, Germany. The "urban" approach includes a specific
urban-type set of economic, social and ecological flood risk criteria, which
focus on urban issues: population and vulnerable groups, differentiated
residential land use classes, areas with social and health care but also
ecological indicators such as recreational urban green spaces. These criteria
are integrated using a "multicriteria decision rule" based on an additive
weighting procedure which is implemented into the software tool
FloodCalc urban. Based on different weighting sets we provide
evidence of where the most flood-prone areas are located in a city.
Furthermore, we can show that with an increasing inundation extent it is both
the social and the economic risks that strongly increase. |
