Trends in the Development of Deformations of the Turiya Riverbed (Volyn Polissia).

Abstract

The paper presents a retrospective analysis of the dynamics of channel processes of the Turiya River plain over many years. The data from hydrometric and hydrological observations at the Kovel hydrological observation point since 1983 have been analyzed. The flow rates and water levels of the river, as well as changes in the transverse profile of the channel over different years, were evaluated; corresponding diagrams were constructed. A separate comparison of topographic maps and space images of this territory at various times was carried out to track horizontal deformations of the riverbed. Areas of minimal changes, as well as significant (up to 140 m) channel displacements, were identified. Trends in the development of channel deformations were assessed, and periods of dominance of erosive or accumulative channel processes were highlighted.
