EVALUATION OF DENİZLİ SKI CENTRE IN TERMS OF AVALANCHE SUSCEPTIBILITY

Abstract

Avalanches, which occur in areas far from settlements and where the human population is relatively less, have started to occur more frequently and cause more loss of life and property due to the increasing human population, the gradual expansion of settlements and road networks, and the increasing interest in ski resorts, nature sports and winter tourism. Avalanches, which can reach speeds of up to 400 kilometres per hour, occur very suddenly and most people cannot escape. Today, it is not possible to change the nature of avalanches and prevent avalanches. In order to prevent damages caused by avalanches, it is necessary to prepare potential avalanche susceptibility maps. In this way, dangerous areas can be identified and it will be possible to predict, prevent and reduce the impact of avalanches. In this study, it was aimed to evaluate Denizli Ski Centre and its immediate surroundings in terms of avalanche susceptibility. For this purpose, Geographical Information Systems programme was used and land use, elevation, slope slope, aspect and slope shape parameters were used for avalanche susceptibility analysis and potential source areas for avalanche development were determined. After this stage, areas with high, medium and low avalanche susceptibility were determined by using Conefall software. Thus, it is aimed to make healthier planning for decision makers and local administrations by making use of susceptibility maps for Denizli Ski Resort and to reveal areas with high, medium and low avalanche safety in terms of runways, roads and ski facilities.
