Abstract. The article considers intermediate research results and opportunities for obtaining new geological and geomorphological data when establishing survey sites on the most dynamic objects of the Oka River valley bottom — the erosional banks of the river bends. The article presents a methodology of thematic studies using various methods applied to the Ryazan extension of the Oka floodplain (which is 743–660 km from the river mouth) over the past decade (2013–2023). It accounts for the cause-and-effect relationships of coastal morpholithodynamics and the spatial relation with the geological, hydrological and topological factors of relief formation. Using data from the Dyadkovo semi-stationary observation site, the research reveals the relationship between one-, two- and three-dimensional erosive components. It also discusses the possibilities of expanding this methodology, involving novel and traditional approaches from geographical disciplines related to geomorphology.

 

Keywords: floodplain, Oka River, unmanned aerial vehicle, hydrological year, geodetic survey, geomorphological land survey, geomorphologic semi-stationary site.
