| Zusammenfassung |
| Dynamics of large amplitude internal waves in two-layers of shallow water is
considered. It is demonstrated that in laboratory experiments the subsurface
waves of depression over a shelf may be simulated by internal symmetric
solitary waves of the mode 2 ("lump-like" waves). The mathematical model
describing the propagation and decaying of large internal waves in two-layer
fluid is introduced. It is a variant of Choi-Camassa equations with
hydrostatic pressure distribution in one of the layers. It is shown that the
numerical scheme developed for the Green-Naghdi equations in open channel
flows may be applied for the description of large amplitude internal waves over a
shelf. |
