... and the immersed weight transport rate, which allow longshore sediment transport to be specified, can be derived. Moreover, the same quantities are evaluated with reference to the spectral wave related to the above sea states. An example involving a beach situated in the Ligurian Gulf, Italy, is proposed...

... The threshold of movement of a, sand bottom under random waves is analysed through an experimental investigation carried out in a wave tank by adopting proper wave groups. The results obtained show that the regular spectral waves associated with the sea, states corresponding to the groups...
