ABSTRACT

Risk assessment includes quantitative estimation of damage to a linear engineering structure by exogenous geological processes. Remote sensing data processing using the mathematical morphology of landscape seems to be a promising approach of exogenous hazard risk assessment for linear structures, this issue is examined taking thermokarst plains as an example. The mathematical models of landscape morphological patterns for thermokarst lacustrine plains and thermokarst plains with fluvial erosion is a base of the suggested approach.. As a result we get size distributions of thermokarst depressions (lakes) within thermokarst lacustrine plains and thermokarst plains with fluvial erosion, which allow us to find impact probability of a certain depression at a given distance from a linear structure. Another case deals with continuous appearance and growth of thermokarst depressions; impact probability assessment on linear constructions is done for this case. All theoretical decisions were empirically tested using high precision remote sensing imagery.

Keywords: Mathematical modeling; thermokarst lake plains; thremokarst plain with fluvial erosion; landscape mathematical morphology.
