Gis-Based Avalanche Susceptibility Mapping For Davraz Mountain, Isparta, Turkey

Kerem Hepdeniz, Oya Cengiz

Abstract


Due to its geographical features, Davraz Mountain is an important centre for winter tourism. The ski tracks at 2,150 metres above sea level, thick snow cover, sloping structure and slopes

devoid of vegetation cover increase the avalanche potential in the area.

 

In this study, potential avalanche zones were determined for Davraz Mountain in Isparta province, and maps of susceptibility and the propagation zone were developed. For these analyses, geographic information systems (GIS) and CONEFALL programs were used. Elevation, slope, aspect, curvature and land use parameters were used in the creation of the maps. From the analysis, it was found that Davraz Mountain’s southern side carries an avalanche risk. The northern slope, where the facilities are situated, was determined to be safer.

In the absence of such a study of Davraz Mountain, it is thought that these theoretically prepared maps can be used as a guide for planning, risk management and location site selection for decision makers and local governments.
