Basic Principles of the Hydraulic Theory of Formation and Development of River Channel Mesoforms
A closed system of equations was obtained which describes the formation of river channel mesoforms. The conditions were found which cause recurrent restructuring of the flow velocity field which governs the shape and dimensions of the channel mesoforms. The evolution of the longitudinal profile of a mesoform is considered and the parameters that control this process are evaluated. A numerical solution of the problem of river channel mesoform development is given. An interpretation of the hydraulic theory in terms of energy is given.
