详细
A general equation of vertical deformations of the longitudinal profile of a river channel is proposed. It describes the change in time of the altitudes of alluvial river bed due to the change in the flow’s transport capacity along the length of the flow; abrasion and erosion of bedrock of the river bottom; the effect of sediment supply from slopes, and the general change in heights in the river basin due to tectonic movements. These processes and effects are described by empirical mathematical functions that depend on time, longitudinal coordinate, hydraulic characteristics of the flow and conditions in the catchment area and on the territory. The components of the general equation and of the mathematical expressions of individual processes are considered and the main combinations of erosion, stability and accumulation conditions in the river channel are obtained.
