A variety of factors include climatically induced changes of the river runoff and sediment load, glacial advances and rapid variations of the base level, as well as the influence of the tectonic factor. The first-order climatic cycles are reflected
in separate terrace fills. The second-order fluctuations may be represented by separate cuts and fills, by the change of the facies or in the granulometric composition. The analysis of the changes in the longitudinal profile helped to discover different valley
