Abstract: | The concepts of subcritical and supercritical flows are introduced for the long-wave approximation model describing stationary
free-boundary rotational flows of an ideal incompressible fluid. Shear flows of a fluid layer above an uneven bottom are analyzed.
Exact solutions describing different flow regimes are constructed, and the flow properties are studied as a function of the
flow regime. Flows with backward streamlines are considered.
