The tidal bore, is an enomene of abrupt elevation of the water of a river or an estuary caused by the wave of the rising tide during high tides. This phenomenon occurs in the mouth and the lower course of some rivers when their current is thwarted by the flow of the rising tide. The most spectacular tidal bore can be seen at the mouths of the Qiantang (China), the Severn (England) and the Amazon (in Brazil). Physically, the tidal bore corresponds to the propagation of a projection along the course of a river or a canal.

Gironde : comment connaître les meilleurs jours pour surfer le mascaret ?

The Tidal Bore allows surfers to engage in the distance-on-the-wave competition. The Tidal Bore advances at a speed of 10 to 20 km / h (the less there is, the more it slows down), the wave can reach 1.36 meters in height but is not constant. As the bottom changes, the succession of waves moves across the width of the Dordogne (commune of Saint pardon) and widens, flattens, bulges, surges, bubbles, disappears, resurfaces, it is constantly changing.

Blaye

Citadel of Blaye :

The Citadel of Blaye is a magnificent construction which culminates on a rocky promontory above the Gironde.

The Citadel of Blaye covers an area of ​​approximately 38 hectares and was built between 1685 and 1689 by the Director General of the Fortifications of Guyenne: François FERRY under the supervision of Sébastien Le Prestre Marquis de VAUBAN.

The purpose of the Citadel of Blaye was to control navigation on the Gironde Estuary. But this construction was not sufficient in view of the width of the Gironde and especially the range of the cannons at that time.

VAUBAN thus took advantage of the disposition of the Ile Pâtée between the banks of Blaye and of the Médoc to imagine a triple defence called: The Lock of the Estuary. Enemy ships wishing to return to the land and to Bordeaux were caught in a crossfire from this triple defence consisting of the Citadel of Blaye, Fort Pâté and Fort Médoc.

The islands in the estuary :

At the same time you can visit the islands of the estuary which are : L’île Nouvelle, l’île Margaux, l’île de Patiras and the lighthouse of Courdouan.

The New Island
