Abstract
In the experimental study the parameters of nonlinear stationary waves in the flow with velocity gradient changing along the flow from 0.01 to 0.3 s(-1) for Froude numbers from 0.4 to 1.3 were determined. Insta bility of waves with high steepness was found. The waves with large st eepness arise in the region of high dispersion, stationary three-dimen sional plane shorter waves take place in the region with low dispersio n. Solitons generation at critical Froude numbers in the flow with vel ocity gradient and solitons generation by steep waves at subcritical F roude numbers were found.
