ANTHROPOGENIC DEBRIS FLOW IN THE SHYMBULAK RIVER BASIN ON JUNE 30, 2024

The results of the analysis of the authors' field and office research materials, video and photo, morphometric characteristics, and meteorological conditions that preceded forming the debris flow on June 30 in the Shymbulak River basin presents in the paper. Economic activity in the catchment area of the Shymbulak River basin created unstable conditions that determined forming the debris flow during rainfall on June 30. It was established, that disturbance of the soil-vegetation covers during the slope profiling and planning work for ski slopes increases the probability of forming debris flows in the Shymbulak River basin. A significant share of the blame for encouraging and permitting the design and construction of ski slopes in the debris flow hazards areas lies with scientific and government organizations responsible for environmental protection. Identifying factors and mechanisms of debris-flow forming helps to solve the problems for debris flow forecasting.
