Modelling of tides, waves and currents in coastal waters : hydrodynamics of the Firth of Clyde and of the east coast of Scotland
The thesis here presented is based on three main parts. The first part of the thes is based on modelling the water circulation of the Clyde Sea, in order to understand the dynamics of the dispersion of the Neprophs larvae. Previous researches in this area of Scotland highlighted the importance of th...

Crossing sea is one of the most common state in world seas, and occurs when a wind-generated wave train interact with another train of waves, that can be swell waves or another wind-generated wave train, maybe caused by a rapidly turning wind direction.
