Аннотация

To estimate the direction and rate of vertical riverbed deformations the curves of regression were obtained for rivers' level and discharge. The longitudinal profiles of some rivers were plotted. The predominant type of profiles is concave one, which relates to growth of discharge and decrease of gradient downstream. The bed with well-developed alluvial forms is incidental to all rivers with water surface slope less then 20%. The middle and lower streams of the rivers in the zones transient from mountains to basins and littoral plains may be considered as mountain rivers. In volcanic areas equilibrium river profile should be calculated taking into account the density of incoming piroclastic material.
