Conditions of formation and development of landslide processes in the Tentek river valley

Abstract

One of the trends that threaten human settlements, and roads, arising from the shift of loess, bentonite montmorillonite clay rocks on the surface of thick moraine deposits under the action of gravitational forces during the water, the absorption is widespread landslides in the intermountain depressions of Altay, Tarbagatay, Zhetysu, Zaili, and Kungey Alatau and large river valleys. 

In the article, the conditions of the formation of the thermal process arising under the action of gravitational forces in the areas of distribution of loess, bentonite clay rocks on the slopes of the Tentek river valley in the north-eastern part of Zhetysu Alatau and their threats to human life, as well as socio-economic important objects and measures to combat them are considered. 

To explore the content of the topic, as well as to identify the causes of the movement of bentonite-montmorillonite muddy sediments affecting the course of the thermal process, a three-fold expedition survey was organized in the valley of the Shet Tentek, Middle Tentek, and Lower Tentek rivers in 2022-2023.
