| Zusammenfassung |
| The analysis and comparison of the results of numerical experiments on the long waves run-up on a coast with a variety of bottom profiles in the framework of the nonlinear theory of shallow water have been performed in this work. Two types of one-dimensional problems are solved: in the first case the bottom profile is represented as a flat slope; in the second - the so-called non-reflecting profile. In both cases the run-up area in deep water is conjugated with a flat bottom, and on the beach - with a vertical wall. It is shown that for small amplitude waves the amplification of the incident wave's amplitude is higher on non-reflecting bottom profile, rather than on a flat bottom profile. With the increasing of the incident wave's amplitude, wave breaking near the coast occurs earlier on non-reflecting bottom profile, and therefore the amplitude decreases faster than on a plane beach. The behavior of breaking waves approaching and running-up the wall on non-reflecting and flat bottom profiles is demonstrated.
