LABORATORY STUDY INFLUENCE OF FLOW ON THAWING OF UNDERWATER SLOPES AND THE PACE COASTAL EROSION OF RIVERS, OCCURING IN THE PERMAFROST ZONE

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...

Description
Summary: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].
