Bilan des tempêtes de l’hiver 2013-2014 sur la dynamique de recul du trait de côte en Bretagne ArchiMer

Between December 2013 and March 2014, a cluster of about 12 storm events hit the coast of Brittany with an exceptional frequency. It was in February that these storm events were the most frequent and particularly virulent. The significant wave heights measured off Finistere reached respectively 12.3 m and 12.4 m during Petra and Ulla storms on February 5 and 14. However, analysis of hydrodynamic conditions shows that only three episodes promoted extreme morphogenetic conditions because they were combined with high spring tide level. The first one occurred on January 1 to 4, it was followed by events from February 1 to 3, and March 2-3. During these three extreme events observed tide levels were above highest astronomical tide level (HAT). Maximum surge...

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...

Surges, atmospheric pressure and wind change and flooding probability on the Atlantic coast of France ArchiMer
Pirazzoli, Paolo Antonio.
A statistical study of hourly tide-gauge records at Saint-Gildas, Saint-Nazaire, Port Tudy, Brest, Le Conquet and Roscoff, as well of three-hourly wind and air pressure records at Belie lie and Ouessant over the last 50 years, has made possible the definition of the main meteorological factors which are associated with the development of positive or negative surges. Recent changes in these meteorological factors indicate that atmospheric depressions and strong surge winds are becoming less frequent and that the ongoing trends of climate variability show a decrease in the frequency and hence the gravity of coastal flooding. However the highest sea surges of the last decades did not occur at the time of spring high tide. There is a significant statistical...
