ABSTRACT

Manifestations of exogenous geodynamic processes in geomorphological objects at this stage is defined as damaging or destroying human life environment, leading to significant changes in the structure of the earth’s surface. The term "exogenous geodinamic processes" refers to the concept of EA Likhachev, DA Timofeev "geomorphological danger" by the actions of these processes may be a crisis, disaster or catastrophe for a particular community of people and their economic structure. The factors leading to the expression of exogenous geodynamic processes in key areas of geomorphological objects taiga zone of the West Siberian Plain are: neotectonic movements, lithogenic properties, climatic and hydrological conditions. Spatio-temporal transformation of valley landscapes of the West Siberian Plain under the influence of exogenous geodynamic processes determines the need to systematize the information on the distribution, activation of the facts of the processes in specific situations to assess the risks of natural and technogenic systems.
Erosion and channel processes are subject to a number of common patterns and factors such as the spatial and temporal relations, relations with the natural climatic environment, which have been investigated in key ranges in lowland landscapes middle course Ob. Key polygons match to the tectonic faults, where monitoring of exogenous geodynamic and fluvial processes conducted for 15 years by a fixed terrain of bench marks for ranges; since 2014 used in the study 2 satellite receivers Leica GS10, geodetic measurements are made. Spatial analysis of the territory was performed on the material of information and space technologies Ugra Research Institute of Information Technologies (Khanty-Mansiysk). Data temperature’s of the soil, within key polygons fixed by thermochrons type DS1921G-F5 - for depth: 20 cm, 40 cm, 60 cm and 1 m, and type DS1921Z-F5 - depths of 2 m, 3 m, 4 m, 5 m and 6 m. Hydro-meteorological indicators were analyzed according to dates of the Nizhnevartovsk’s stream flow measuring station by Tyumen region and Alexander’s stream flow measuring station by Tomsk region.
