| Zusammenfassung |
| Run-up of long waves on a beach consisting of three pieces of constant but
different slopes is studied. Linear shallow-water theory is used for incoming
impulse evolution, and nonlinear corrections are obtained for the run-up
stage. It is demonstrated that bottom profile influences the run-up
characteristics and can lead to resonance effects: increase of wave height,
particle velocity, and number of oscillations. Simple parameterization of
tsunami source through an earthquake magnitude is used to calculate the
run-up height versus earthquake magnitude. It is shown that resonance effects
lead to the sufficient increase of run-up heights for the weakest
earthquakes, and a tsunami wave does not break on chosen bottom relief if the
earthquake magnitude does not exceed 7.8. |
