Mathematical models of long-wave approximation for a three-layer fluid are considered taking into account mixing and entrainment at the interfaces of the layers. These nonlinear models are used to describe changes in the nature of non-uniform flows when passing over localized elevations of the bottom. Comparison of the results of numerical calculations with the data of field measurements shows that the models adequately reproduce the structure of shelf and deep-water currents, in which the flow splits with subsequent thickening of the passive intermediate layer and formation of an intense inclined jet behind an obstacle.
