Türkiye'nin Üç Pilot İlinde Çığ Tehlike ve Risk Analizleri: Bitlis, Van ve Antalya Örnekleri.

Avalanche is defined as the movement of the snow layer accumulated on the sloping slopes of mountains where there is no or sparse forest cover due to the effect of gravity from its position for various reasons and causes unpredictable great loss of life and property. Avalanches pose a serious threat to settlements, highways, ski resorts and facilities planned in mountainous areas in Bitlis, Van and Antalya provinces in terms of topographic and climatic characteristics of Turkey. In this study, field investigations were carried out in 3 pilot provinces and information was obtained from local people about the avalanche risk areas. Then, for these pilot regions, avalanche initiation zones, 2D avalanche simulations with RAMMS (Rapid Mass Movement Simulation) software, avalanche hazard maps, risk analyses and prioritisations for avalanche risk reduction were made. Operational and structural avalanche risk mitigation methods were proposed in the risky areas determined according to the prioritisations. This study emphasises the importance of using avalanche hazard maps in the planning of existing and future settlements, highways, tourism facilities, etc., and contributes to a better understanding of avalanche disaster by performing qualitative and quantitative risk analyses.
