| Zusammenfassung |
| In Switzerland, floods, debris flows, landslides and rockfalls cause damage
every year affecting property values, infrastructure, forestry and
agriculture. As population and settled areas have increased, the damage
potential has also become greater. Information about natural hazard events
that caused any damage is needed for hazard mapping and further decision
making. This is why the Swiss Federal Research Institute WSL has been
systematically collecting information on flood and mass movement damage in a
database since 1972. The estimated direct financial damage as well as
fatalities and injured people have been documented using press articles as
the main source of information. The database can provide answers to
questions related to the temporal and spatial distribution of damage,
natural hazard processes and the corresponding weather conditions. This
study describes the data collection methods used and the key analyses of
data from 1972 to 2007. Furthermore, the benefits and drawbacks of the
database are discussed. In Switzerland, naturally triggered floods, debris
flows, landslides and rockfalls have caused financial damage amounting to
nearly 8000 million Euros in total within the last 36 years (taking
inflation into account). These processes have mainly affected pre– and
central alpine regions and their total costs of damage are dominated by a
few major events. Nearly one quarter of the costs result from August 2005
when large parts of Northern Switzerland were affected by flooding. We must
assume that major events like this are not unique and that similar events
will occur again in future. |
