Determination of Potential Avalanche Release Areas, Avalanche Mobile Application and
Preparation of Avalanche Hazard Maps in Türkiye; the Case of Palandöken Ski Centre

Regarding the assessment conducted for hotels, according to the AÇBB
avalanche pressure maps presented in Figure 14, it has been found that the
avalanche pressure in 17th AÇÇB reaches 352 kPa in the 17th AÇBB and up
to 310 kPa in the 21st AÇBB. According to the AÇBB avalanche speed maps
presented in Figure 15, avalanche speeds reach 34.2 m/s in the 17th AÇBB
and 32.1 m/s in the 21st AÇBB. According to the AÇBB avalanche height
maps presented in Figure 16, avalanche heights reach up to 11 meters in the
17th AÇBB and 10 meters in the 21st AÇBB. The values directly impacting the
hotels show that the pressure reaches 264 kPa, the speed reaches 29 m/s, and
the height reaches 4.6 meters. These findings clearly indicate that the hotels
are under significant avalanche risk.
In order to detect the runout zones of avalanches, all potential and active
avalanche starting zones were individually analyzed using the RAMMS
software and two-dimensional simulations were conducted. Unfortunately,
since the previous avalanche event was not recorded, it was not possible to
accurately compare the results of the analysis. An avalanche hazard map was
created based on the results of this simulation (Figure 17).
