Abstract: A long-wave approximation that describes running solitary waves is considered within the framework of the model of a weakly stratified two-layer fluid. It is demonstrated that wave regimes occur near the boundary of the parametric domain of shear instability in the stratified flow. This fact offers an explanation for the mechanism of intense mixing in deep near-bottom layers.

Keywords: two-layer fluid, weak stratification, solitary waves.
