Abstract

In the RUDN hydraulic laboratory researches of destruction of an underwater and surface coastal slope in the conditions imitating a kriolitozona depending on type of the soil composing a slope and a bias corner are executed. It is shown that the speed of an erosion of an underwater slope lags behind the speed of thawing of frozen soil. Work of a water stream considerably exceeds influence of other factors (temperature, wind influence, solar radiation), leading to formation of niches of washing away. Work is continuation of a research of dynamics of a coastal slope of water objects in the conditions of a kriolitozona [1-4].
