Based on empirical evidence from field surveys, morphometric parameters of mudflows were determined. In laboratory conditions, data on the geological structure of slopes, physical and mechanical properties of soils, etc. were obtained. On the site, three mudflow basins were identified, which in case of prolonged heavy rainfall and snowmelt form mudflows causing damage to various-purpose structures, including the ropeway, ski track No.1, engineering protection facilities, haul road, antenna-mast structure No.2, and pedestrian crossing. Based on field surveys, it was established that the existing mudflow protection structures were insufficient to ensure full safety of the existing facilities and adjacent structures. Based on these calculations, the following measures were recommended to stabilise the situation, namely along the Sulimovsky Creek: installation of flexible anti-mudflow barriers, arrangement of a network of drainage ditches, and erosion control. Thus, the structure type recommended for Section Line No. 3 was unsupported mudflow barrier 5-6 m high and 15 m wide. The structure type for Section Line No. 4 was unsupported mudflow barrier 4-5 m high and up to 15 m wide.
