Zusammenfassung |
Building houses in inundation areas is always a risk, since absolute flood
protection is impossible. Where settlements already exist, flood damage must
be kept as small as possible. Suitable means are precautionary measures such
as elevated building configuration or flood adapted use. However, data about
the effects of such measures are rare, and consequently, the efficiency of
different precautionary measures is unclear. To improve the knowledge about
efficient precautionary measures, approximately 1200 private households,
which were affected by the 2002 flood at the river Elbe and its tributaries,
were interviewed about the flood damage of their buildings and contents as
well as about their precautionary measures. The affected households had
little flood experience, i.e. only 15% had experienced a flood before.
59% of the households stated that they did not know, that they live in a
flood prone area. Thus, people were not well prepared, e.g. just 11% had
used and furnished their house in a flood adapted way and only 6% had a
flood adapted building structure. Building precautionary measures are mainly
effective in areas with frequent small floods. But also during the extreme
flood event in 2002 building measures reduced the flood loss. From the six
different building precautionary measures under study, flood adapted use and
adapted interior fitting were the most effective ones. They reduced the
damage ratio for buildings by 46% and 53%, respectively. The damage
ratio for contents was reduced by 48% due to flood adapted use and by
53% due to flood adapted interior fitting. The 2002 flood motivated a
relatively large number of people to implement private precautionary
measures, but still much more could be done. Hence, to further reduce flood
losses, people's motivation to invest in precaution should be improved. More
information campaigns and financial incentives should be issued to encourage
precautionary measures. |
