Deformations of the channel are a consequence of the development of denudation processes in the basin area, increase in the volume of solid runoff and deposition of debris of the rock, its fractional redistribution in the channels, which especially increase during floods and flooding. They cause changes in the hydrological regime and structure of the river system, the destruction of residential and commercial buildings, as well as the infrastructure in the floodplain. Trends, magnitudes and intensity of deformations of riverbeds are formed by a complex of natural and man-made factors. Neglecting the planned and high-altitude displacements of riverbeds often leads to unpredictable consequences. Washing the shore can cause a gas or oil pipeline to rupture, leading to a strong explosion and fire, as well as oil pollution and environmental damage. Channel processes are associated with the washing of bridge piers, power lines, significant material losses and even human casualties during floods and flooding. The aim of the work is to analyze the development of channel processes in the basin of the river Stryi and forecast the deformation of its channel. The results of the analysis show that the riverbeds of Prykarpattia are very unstable and are characterized by intense erosion of the banks and bottom, which is caused by the influence of various factors. It is a man-made activity that includes the development of gravel quarries in floodplains and riverbeds and their straightening, runoff regulation, changes in forestry and land use. Natural factors, such as climate change and water runoff, etc., are also affected. It was found that the bed of the river Stryi does not have a stable shape, significantly changed the configuration, significantly reduced multi-sleeved and increased its straightness, and in some places the river changed its position by 60–80 meters. Restoration works carried out in some parts of the riverbed during this period were not effective enough. Water in different parts of the riverbed washes the shores, which causes dangerous landslides that occur directly near the riverbed. In these areas, it is necessary to more effectively carry out measures to regulate runoff and restore shore protection.
