Abstract

In this contribution the performance is shown of a hybrid spectral-spatial implementation of the AB model for uni-directional waves above varying bottom. For irregular waves of JONSWAP-type, with peak periods of 9 and 12[s], significant wave height of 3[m], running from 30 to 15[m] depth over a 1:20 slope, comparison with scaled experimental data show reasonable (for the 9[s] wave) to good (for the 12[s] wave) results in calculation times less than 15% of the physical time. Especially, the most extreme, freak-like, waves are well simulated for both cases
