APPLICATION OF QUANTITATIVE METHODS FOR THE ASSESSMENT OF LANDSLIDE SUSCEPTIBILITY OF THE GIRDIMANCHAYRIVER BASIN

Abstract

Among the most dangerous natural disasters, leading to economic damage and human casualties, are landslides, which, unfortunately, have not been given due attention to the study and study of their impact on mudflow processes. For minimize damage from landslides on the example of the Girdymanchay river basin a detailed study of the factors (hypsometry, slope angles, was carried out by us. Also slope exposure, geological structure, distance from faults, average annual precipitation, distance to the erosion network, distance to roads and land use) that determine the development of landslide processes with taking into account the mechanism of their development, as well as an analysis of the obtained values of landslide susceptibility and their potential development was studied. Using the natural boundary classification method in the ArcGIS software environ- ment, the study area was divided into five landslide potential zones: very low, low, medium, high, and very high.
