Scientific work is devoted to the development and improvement of new high-speed structures with artificial roughness, connecting the upper and lower beams of hydraulic structures. The main purpose of these hydraulic structures is not to allow water to flow downstream, flowing at high speeds in mountainous areas of our southern regions and to create a safe hydraulic regime in open canals. In this case, the excess kinetic energy of the falling water from the top of the water is necessary to soak for a relatively short distance and time with the help of specially developed fast currents with artificial flow. In our research, the main attention is paid to the economy, durability and reliability, simplicity of construction, rationality and simplicity in the implementation of the form, etc. We assume that the design of the fast current with a positive solution obtained in the utility model, with account of the circumstances, corresponds to the requirements to it.
