| Zusammenfassung |
| We have previously reported (Zeng and Trulsen, presentation at EGU 2010) that
waves propagating over a shoal may experience a dynamic relaxation over some
distance in order to reach an equilibrium state corresponding to the new local
depth. This can provoke local values of kurtosis different from the
equilibrium value expected for a flat bottom of the same given depth. This
may provoke localized regions of increased freak wave probability.
Recent experimental results from MARIN (provided by T. Bunnik, J. Hennig and
C. Schmittner) may shed some light on the problem of non-equilibrium values of
kurtosis, and in particular, localized regions of increased kurtosis. We show
how the numerical and the experimental data are related. |
