A coastal monitoring system offers multiple opportunities to observe in detail and with high frequency (10 minutes) the physical processes that take place on the coast. In particular, the WaveCams image acquisition technology allows us to obtain diverse hydrodynamic parameters of high interest in the beach’s dynamics. In the example of this video taken in the famous bay of Etretat in France, we can easily observe how a strong longitudinal current develops in medium wave conditions coming from the NW (waves between 1 and 2 meters). Longshore currents are one of the most powerful driven of sediment transport in the coast, and their predominant direction strongly determines how sediments shrink […]
