THE MORPHOLOGICAL PATTERN DEVELOPMENT OF THERMOKARST PLAINS WITH FLUVIAL EROSION: STOCHASTIC MODELING FOR RISK ASSESSMENT

Victorov, A.; Orlov, T.; Kapralova, V.; Trapeznikova, O.

Abstract:

Thermokarst plains with fluvial erosion were studied for the prognosis of their development including natural exogenous hazards. These plains develop through two contrasting processes: 1) thermokarst lakes appearing and increasing in size, 2) drainage of the lakes through fluvial erosion and their transformation into khasireis (drained thermokarst depressions). The present research deals with four different variants of development of the thermokarst plains with fluvial erosion. The research uses mathematical models of the morphological pattern of the thermokarst plains with fluvial erosion, based on the mathematical morphology of landscapes. We analyzed four variants of assumptions using mathematical models for sites with uniform natural environments. The mathematical analysis of the models gives the mathematical laws for the morphological patterns of the thermokarst plains with fluvial erosion for those four variants, which were empirically tested using remote imagery for different regions within Cryolithozone.
