The object of study - the Kolka Glacier - is located on the side ridge of the Central Caucasus. The glacier is known for its catastrophic events — large-scale moves and glacial landslides. This glaciological object can also be considered unique due to the fact that despite the general degradation of the Caucasus glaciation, the Kolka glacier is rapidly gaining mass. Due to the rapid recovery of the glacier, the repetition of previous catastrophic events is possible, and that is why it is necessary to constantly monitor its condition. It's safe to assume that such rapid rates of recovery occur due to the significant share of avalanche feeding that the glacier receives from the steep rock framing of the town of Dzhimaray-Khokh.Currently, there are techniques to assess the role of avalanche nutrition, one of them being a two-dimensional RAMMS model, created on the basis of the onedimensional hydraulic Velmi-Salm model. This model allows us to simulate the movement of the avalanche flow in a three-dimensional relief. This work's purpose consists in evaluation of the role of avalanche feeding on the Kolka glacier. The tasks that were performed in the course of the work were to isolate avalanche foci on the rocky frame of the glacier, identify zones with different friction coefficients, and simulate avalanche flows via RAMMS model in three-dimensional relief conditions. The result of this work is the avalanche deposits distribution pattern on the Kolka glacier and the boundary comparison of the sediments with their previous distribution estimate.
