Abstract

The characteristics of sedimentation and the properties of different types of sediments of the lakes of the Saralinsky area of the Volzhsko-Kamsky state nature biosphere reserve, formed in the middle of the 20th century during the flooding of depressions II above the floodplain terrace of the river Volga by the waters of the Kuibyshev reservoir, are given. The structure of upper sediments is dominated by sandy silts; buried peat and macrophytes are found in a number of lakes. The lake sedimentation occurs mainly due to the influx of terrigenous matter from the catchment area, and in a number of lakes that have not lost their connection with the reservoir due to river alluvium. The total sediment thickness did not exceed 50 cm. The average sedimentation rate in the lakes varies from 1.0 to 2.5 mm / year, and the maximum one reaches 7.5 mm / year. Over the 60 years of their existence, the lakes have silted up by an average of 8%.
