| Zusammenfassung |
| In Turkey, an average of 24 people die in snow avalanches every year, mainly
in the eastern part of Anatolia and in the eastern Black Sea region, where
high-mountain ranges are close to the sea. The proportion of people killed in
buildings is very high (87%), especially in comparison to other European countries
and North America. In this paper we discuss avalanche occurrence, the
climatic situation and historical avalanche events in Turkey; in addition, we
identify bottlenecks and suggest solutions to tackle avalanche problems.
Furthermore, we have applied the numerical avalanche simulation software
RAMMS (rapid mass movements simulation) combined with a (digital elevation model) DEM-based potential release
zone identification algorithm to analyze the catastrophic avalanche events in
the villages of Üzengili (Bayburt province) in 1993 and Yaylaönü
(Trabzon province) in 1981. The results demonstrate the value of such an
approach for regions with poor avalanche databases, enabling the calculation
of different scenarios and the estimation of run-out distances, impact
pressure and flow height. |
