Abstract
In recent years, the number of natural disasters has significantly increased, including those caused by exogenous geological processes, one of the leading among which are landslides, leading to environmental, engineering, social and economic consequences. The investigated Chirchik basin of the Republic of Uzbekistan is characterized by complex geomorphological, hydrological and geological conditions, as well as the presence of an active geodynamic process, which predetermined the development of landslides here. Currently, various methods are used for the integrated study of landslides of various genesis. Along with traditional methods, various tools of geographic information systems (GIS) are widely used. The use of GIS-processing of digital elevation models makes it possible to fully describe the development of landslide processes: quickly obtain information about morphometric indicators (height, inclination angle, slope exposure) in any model, analyze slope steepness and exposure, frequency runoff, generate contour lines, etc., as well as to map them. Another method of research is the method of relief plastics, the essence of which is the geometric transformation of the contours of topographic maps, it consists in the use of a new topographic map—relief plastics based on litodynamic flows. The proposed methodology for the integrated application of GIS technologies and plastic flow maps was developed taking into account the work performed by foreign and domestic specialists. This methodology applied to landslide processes study in the Baibaksay-Sulisay section of the Chirchik basin. As a result, digital elevation models were compiled based on SRTM and QiuckBird remote sensing materials, based on the digital elevation model, using the theory, a map of convex and concave surfaces was created.
