摘要：
The concepts of sub- and supercritical flows are introduced for the longwave approximation model describing the steady-state horizontal-shear motions of an ideal incompressible fluid with a free boundary in a channel of variable cross-section. Fluid layer flows developed in a local channel contraction or expansion are analyzed. Continuous and discontinuous exact solutions describing different flow regimes are constructed and their properties are studied. Flows with the formation of recirculation zones are considered.
