Abstract (English):
The paper features the dynamic peculiarities of mudflow deposits and the methods of their volume calculation. It was determined that peculiarities of torrents are defined by their dynamic and velocity. It was revealed that the relation of accumulation volume to the abrasion volume of the debris cone of the water stage gauge in Balakançhay. Talaçhay Mukhakhchay and Kurmukchay is 0.66; 0.014; 1.35 and 0.7 accordingly. The violation factor of the mudflows in the river basins also forms 0.37; 0.28; 0.56 and 0.30 accordingly. As for the general territory, the range stays within the limits of 0.03-059. It is determined that the rate of decrease in the surface of the catchment areas caused by mudflows is 5.14 mm on the Balakenchay river, 11.81 mm in the Talachay river, 9.44 mm in the Mukhakhchay river, 5.68 mm in the river Kurmukchay, 11.21 mm in the river Shinchay and 9.09 mm in the river Kish. The average value is 8.73 mm. The relatively high value of the washout intensity is characteristic of the catchment area of the Talachay river and the Shinchay river, which is due to the spread of fragile rocks, the presence of significantly exposed areas with great slope steepness and their dismemberment, as well as cost-effective deforestation.
