| Zusammenfassung |
| The assessment of historical data of small mountain torrents in Alpine
catchment areas has shown a significant difference between the results of a
regular hazard zone mapping and a thorough historical analysis. The Gemsbach
in the Ostrach valley near Hinterstein (Municipality of Hindelang, southern
Bavaria/Germany) serves, among others, as an example. A "traditional"
hazard zone for the Gemsbach has been mapped in the 1990s. The oldest event
included in the analysis was the flood of 1954. But historical data
collected and analysed by the HANG-project shows flood-prone areas around
the Gemsbach differing greatly in size and location from the one shown in
the hazard zone maps. The inclusion of all data available for the Gemsbach
area (15 events between 1671 and 1960 collected from four different
archives) leads to a completely new picture of the regional hazardous
activity and demands a re-structuring of the traditional way of hazard zone
mapping. |
