| Zusammenfassung |
| The propagation of
nonlinear surface waves in channels of smoothly variable in space cross
section is studied theoretically and by means of numerical computations.
The mathematical model describing wave evolution is based on the
generalized Korteweg-de Vries equation with additional terms due to
spatial inhomogeneity and energy dissipation. Specifically we consider
channels of variable depth and width. The breaking of Riemann waves and
the disintegration of hydraulic jumps into trains of solitons have been
examined. The results obtained can be useful in particular for the
understanding some peculiarities of bore (mascaret) formation, viscous
evolution and disintegration into solitons in inhomogeneous channels or
rivers. |
