Tide and surge dynamics along the Iberian Atlantic coast ArchiMer
Alvarez Fanjul, E; Perez Gomez, B; Carretero, Jc; Rodriguez Sanchez Arevalo, I.
The eastern Atlantic barotropic dynamics (in a region spanning from 20 degrees N to 48 degrees N and 34 degrees W to 0 degrees) are studied through numerical modelling and in situ measurements. The main source of data is the tidal gauge network REDMAR, managed by Clima Maritimo (Puertos del Estado). The numerical model employed is the HAMSOM, developed both by the Institut fur Meereskunde (Hamburg University) and Clima Maritime. In this paper, tidal and storm surge dynamics are studied for the region, focusing particularly on the nonlinear transfer of energy between the different forcings. The results of tidal simulations show good agreement between semidiurnal harmonic components and the values obtained from the tidal gauges (both coastal and pelagic) and...

Contribution à l'étude du couplage entre diffusion d'eau et contrainte mécaniques dans les matériaux marins hautes performances ArchiMer
Humeau, Corentin.
The aim of the study was to understand the impact of coupling on water diffusion and mechanical stress on marine installations. Moreover, we identified the key phenomena involved during this type of exposure. When we look to these type of applications we can distinguish two type of materials used: one for the structure and another for mooring facilities. The best performing structural materials appear to be composites, while the most effective mooring devices are made with synthetic ropes. Therefore, we decided to investigate both materials with the same method: first the properties uncoupled, second, as semi-coupled behaviours and finally as one coupled phenomenon. The present work highlights the divergences between uncoupled, semi-coupled and coupled...
