ВЛИЯНИЕ ОСАДКОВ В ВИДЕ ДОЖДЯ НА ДЕФОРМАЦИИ БЕРЕГОВОГО СКЛОНА РУСЕЛ РЕК В УСЛОВИЯХ МНОГОЛЕТНЕМЁРЗЛЫХ ПОРОД

We studied in the lab the interaction of river runoff from frozen soil, simulating the upper, active-layer, changing the thermal (warming) and mechanical (impact of rain) external influences. We determined the time of thawing of ground and infiltration in soil, sediment transport along the lines under the influence of slope flows, caused by both natural thawing permafrost and storm flows. A mathematical model for predicting the dynamics of river channels in the permafrost under the influence of external factors is suggested.
