The unstoppable demand of the coast for recreational and tourism activities has increased the need for shore and beach protection, as well as the construction of artificial beaches, ports and harbours. Most coastlines are subjected to the direct impact of wind waves, swell and storm wave activity. As a result, wind waves and wave driven currents are the dominant mechanisms controlling littoral sand transport and determining the nearshore morphology. In addition, many other physical phenomena, such as tides and associated currents, long waves and storm surges, amongst others, can play a significant role in the dynamic behaviour of the coastal zone.
