Khoper River floodplain in the middle reaches morphology and some problems of paleohydrology

Abstract

In the middle reaches of the Khoper River near Povorino town some segments of superimposed floodplain are identified which inherit channel macro-meanders dated to the late glacial and the early Holocene. Two generations of the macro-meanders are distinguished and their parameters are determined. Hydromorphological and hydraulic techniques were used to calculate paleo-discharges necessary to form meanders of the given characteristics. The author arrives at the conclusion that changes in runoff under periglacial conditions of the late glacial were of primary importance in the meanders formation.
