Aim of work is to investigate the influence of the Precarpathian bend and the Volynian-Podolian upland for the nature of displacement of the Dnister River tributaries and to determine stability of river channels. The object of this research is the Dnister River and its left and right tributaries. Considering the main factors influencing the nature of the horizontal riverbed displacements caused by both natural and anthropogenic factors, special attention is focused on the geological structures in the area on which Dnister River and its tributaries flow. Methods. Applying the software package ArcGIS authors had implemented the monitoring for a 100 year period using various topographical, geological, ground maps, and space images. For monitoring of displacements of the riverbeds of right and left bank tributaries of the Dnister there were used: topographic maps at scales 1
It's been established that the problem of disappearing of open water body and the use of Earth remote sensing data for their monitoring is relevant and poorly covered in current Ukrainian and foreign scientific studies. The necessity of complex solution method has been also determined. The purpose of this paper is to study the dynamics of surface water area over a 45-year period (over a long period of time) across the Iziaslav district of Khmelnytsky on the basis of programming analysis of satellite imagery and the results from field surveys at key research sites. In this study, the freely available QGIS software was used to process satellite imagery. Field surveys (implied on the ground) took place at water bodies which disappeared in
