Certain geomorphological characteristics of mudflows Transcarpathian region and their relation with lithology

Abstract

In the article the analysis of the terms of the spatial distribution of mudflows for Transcarpathian region is
given. Particular attention is given to Transcarpathian region, where a lot of mudflow hazard streams, and where
there is a significant intensification of mudflow processes. Using statistical analysis methods, parameter sets that
quantitatively characterize mud processes, such as geometrical parameters - the length, width, the detrital cone
area, proluvium power, material volume and geomorphological settings – the absolute mark, angle of the slope
surface, were evaluated. The results of this analysis indicate that the distribution of the quantitative characteristics
of mudflows is consistent with the log-normal law; significant correlation ties between independent parameters
were found. Research of the impact of lithological, tectonic and geomorphological conditions of the territory on
development of mudflows is given. Analysis of the location of mudflows relative to lithological, complexes and
tectonic zones allows to determine a definite pattern in the mud on flat intensity processes, including the vast
majority of lesions in mud tectonic zoning belongs to Krosnenska zone, and the lithofacies to facies sand flisch.
Mudflow processes manifestation factor to consider distribution in areas related of mudflow hazard and other
exogenous geological processes (landslides, erosion, etc.).
