| Zusammenfassung |
| The nonlinear-dispersive-dissipative dynamics of internal disturbances of large amplitude in closed basins (lakes, bays) with variable bottom is studied in the framework of the Euler equations of incompressible stratified fluid. The results of numerical simulation of initial and boundary problems are presented. Nonlinear waveforms, which can be excited by harmonic force in resonator system or as a result of initial disturbance evolution, are given. Internal solitons of different vertical modes can be generated against the background of a largescale standing mode. The parameter planes showing different regimes of wave dynamics are presented for different parameter pairs. The applicability of possible simplified models is discussed.
