Abstract. The geographic information analysis of the flood inundation area of the Oka floodplain in the Ryazan region (742–662 km away from the estuary), which was performed in 2018, enabled the author of the article to assess the extent of inundated area within the Oka valley. The author investigated the areal extent of inundation of all the morphological complexes of the Oka. GIS-based modelling showed that the segmental-ridge floodplain meander belt was inundated to a greater extent than other local morphological complexes.

Keywords: the Oka river, floodplain, morphological complex, QGIS, inundation area, air photography, satellite imagery analysis.
