The French coast recedes. This is the conclusion drawn by a . Last winter, severe storms resulted in a decline of beaches and dunes on the 200 miles of sandy coast of this region.
According to the public, among the three departments that form the coast of Aquitaine in south-western France, in Gironde is the largest decline was observed. If many sites, the coast has declined by almost 20 meters, the decline could reach almost 40 meters in some areas. The erosion was lower in the department of Landes, between 10 and 25 meters. In the Pyrénées Atlantiques, the coast, mostly rock, was less affected.

How to explain such a statement?
Coastal cord undergoes between December 2013 and March 2014 at least eight tempestuous events. The repetition of these storms on a short period of time is responsible for this erosion. But it is mainly the effect of attacks from the sea who assaulted beaches and dunes. Indeed, the power of the waves, combined with waves of exceptional height, could reach two times higher than seasonal norms values.
Stations of the Medoc were most concerned. For example, in the town of Soulac-sur-Mer, many buildings are threatened by the decline of the dunes.

Local group organizing to fight against the advance of the Atlantic Ocean. Public deliver a real struggle to try to minimize the loss of large amounts of sand. The rock dunes is one of the axes of this struggle.
The necessary investments are consistent in these areas vital to the economic activity of the region, popular with tourists. Millions of euro have been committed by various public authorities.
These storms are they likely to become the rule rather than the exception? Difficult to answer such a question. For one of the elected Médoquine coast, the thing is heard. "In 40 years, our central beach will no longer exist", told the mayor of Lacanau, a town famous for its surfing. "We must be prepared to relocate, perhaps defend, but it has to fit into people's minds: the erosion is not an empty word." Has he concluded.
