%X An understanding of the characteristics of fluvial erosion and deposition is essential for the proper solution of problems related to hydropower and bridge construction, the improvement of inland waterways, agricultural land reclamation, and many other practical tasks. At the same time, any general theory of the development of the geographical environment must take into account the activity of flowing water, since it continuously transforms the landscape.The theory of erosion-deposition and channel processes, as a branch of hydrology, is also studied within several technical disciplines, including hydraulic engineering, hydraulics, and engineering geology, as well as within natural-science disciplines such as physical geography and geomorphology. The foundations of this field were established both by engineers (F. M. Lokhtin and N. S. Lelyavsky) and by specialists in the natural sciences (V. V. Dokuchaev, A. P. Pavlov, I. D. Chersky, and S. N. Nikitin). These two directions, the engineering and the natural-historical approaches, subsequently underwent substantial development and specialization. Today, an enormous body of empirical material has been accumulated, making it possible to identify a series of specific regularities. However, integrating these regularities into a unified system is possible only when flowing water is regarded as an integral component of the geographical environment.Flowing water develops under specific conditions, and the combination of these conditions determines the volume and dynamics of discharge, the average longitudinal gradient, the grain size and mineral composition of alluvial sediments, and, in short, all the principal factors governing the intensity and characteristics of channel-forming activity. It follows that erosion-deposition and channel processes cannot be viewed as an isolated chain of phenomena developing independently of the geographical environment and without regard to the specific features of the drainage-basin landsc
