Model of an undular bore.

- Abstract
In the shallow-water approximation, nonlinear long waves are considered with account for small-scale waves on the free surface. The undular-bore structure, which within the framework of this model is represented as a discontinuous solution with a relaxation zone adjacent to the discontinuity, is investigated. The wave-packet damping rate is found. The solution obtained is compared with the structure of the undular bore determined by the nonlinear dispersion equations of second-approximation shallow-water theory.
