... at the steal water level. This study is concentrated on the distribution of dynamic wave pressures and wave loads on the TPB, under the conditions of regular waves (with the range of relative plate width B/L=0.28∼1.43 and relative wave height H/d=0.1∼0.4) and random waves (with the range of relative plate...

... ABSTRACT Numerical phase-resolved modelling of random waves on large spatiotemporal scale, meanwhile considering sufficient nonlinearities, is very essential to gain insight of the nonlinear wave-wave interaction process and the mechanism of the so-called rogue waves. To do that, it has been...

..., random waves are generated by a serpent-type wavemaker for a representative offshore wave spectrum determined with spectral and directional functions. In shallow water, however, the shapes of directional spectra are deformed and spatially distributed due to shallow water effects. In this paper...
