Abstract

The model of the thermokarst process of permafrost rocks taking into account the thermal sources caused by inhomogeneous absorption of solar radiation in water layer is considered. Analytical solutions of the system of equations allowing to determine thermal regime of permafrost ground and the dynamics of its thawing were obtained.
