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.</span></p>hydrological river regimestreamflowpermafrost degradationгидрологический режим рекстокдеградация вечной мерзлоты[Атлас снежно-ледовых ресурсов мира / Под ред.
