A new phenomenon has been investigated - an increase in the winter and early spring streamflow of northern rivers. Assuming that the increased discharge may be due to permafrost degradation in river basins, the thaw rate was estimated by modeling. A mathematical model that takes into account the typification of the four permafrost categories, reflecting the dependence of the runoff on the cryological conditions of the watershed areas, showed a rapid degradation of sporadic permafrost and expansion of discontinuous permafrost at the account of continuous one.
