2.		I. Course content The purpose of the course is to introduce fluvial processes that are important for training qualified personnel, to strengthen the acquired theoretical and practical knowledge and to teach them how to apply it in practice. The task of the course is to teach students about the physical parameters of flow and sediment, to predict the shape of the bed in streams, to calculate the change in flow resistance, to teach students about the continuity of fluid transport, and the methods of calculating stable alluvial channels. II. The main theoretical part (lectures) II.I. The course includes the following topics: Subject of the course "Fluvial dynamics". The main factors determining the processes in riverbed. Meandering. Determining the main parameters of liquid flow in rivers. Bernoulli's equation. Calculation of flow levels and depths in the river using the correct step and standard step methods. Sediment properties Velocity distribution and flow resistance laws in natural channels. Average flow velocity. Vertical distribution of the velocity. Resistance to flow.
