Aim: The main objective
of the study was to carry out GIS based large scale mapping of snow avalanche
hazard. Aşağı Dere catchment in Bayburt city in Turkey were
selected as study area because many settlements in this area have suffered
and adversely affected from avalanches. For example, avalanche event of 18th
January 1993 caused death of 59 people, injury to 21 people.
avalanche hazard mapping involved: determining potential snow avalanche
release zones; calculation of avalanche extents by 2D snow avalanche
simulation software and generating hazard maps by combining previous two
steps. Four villages that suffered snow avalanches were also evaluated in
terms of avalanche hazard.
total, 3502 release zones, that cover 1992.2 ha (10.3%) of study area were
determined. 7269.1 ha that is 37.5% of total area.
Interpretation: Hazardous areas in
terms of avalanches need to be determined for definition of avalanche hazard
situation and for land use planning. To create hazard maps in terms of snow
avalanches, the most feasible approach is the use of Geographical Information
Systems, combining topographical parameters.
