Abstract: A new definition of wave groupiness factor is proposed here based on wave-height history of wave trains. This new definition takes into account the dual roles of both zero-downcrossing wave height and wave period in the ...

Abstract: A series of physical experiments under wave-only and combined wave-current conditions are conducted in a large-scale wave flume. It is found that waves with strong nonlinearity may lead to downstream movement of the maximum ...

Abstract: The processes of ripple evolution are studied through numerical simulation using a coupled computational fluid dynamics (CFD)–discrete particle method (DPM) model with focus on discussing the effect of the size of the ...

Abstract: AbstractThis study experimentally investigated the settling and drag characteristics of porous and irregularly shaped coral particles with sizes ranging from 0.59 to 8.32 mm. Shape characteristics and settling velocities ...
