Abstract

Сhannel deformations of the Desna River near Chernihiv city were analyzed based on field studies and analysis of various temporal cartographic materials and space images. The hydrological regime of the river is characterized by intensive channel processes, which can be rather hazardous for the functioning of residential and economic infrastructure. Today, there is a rather worring situation on the northeastern outskirts of Chernihiv city, where the channel meander is at the final stage of its development and in the period of the nearest high floods, the formation of a straightening duct and the transformation of the meander into a flood channel is possible. As a result, the river, which flows directly along the city outskirts and widely used for recreational purposes, will become several kilometers away from the city. Based on the study of the hydrological regime of the river, quantitative assessment of the morphological parameters of the river, and the nature and intensity of the transformation of the meander over a long period as well as the forecast of the development of the meander for the coming years were made. Measures to stabilize the conditions of the river channel were proposed.
