Description :
Some bays having the same isostatic rebound and dynamic conditions have been studied to test if the number of beach ridges in each locality is significant to prove climatic changes, storminess, and rates of sediment accumulation, or if the number of beach ridges in each bay is only dependent on their intrinsic characteristics and self organization. Because the number of ridges varies not only from bay to bay, but even within the same bay, it has to be accounted for by contrasting internal and local evolution (sediment supply, offshore gradient and coastal evolution). These differences between various or parts of the same bay invalidate the explanations that global processes (planetary orbital forces, relative sea-level changes or past climatic condition) are responsible for beach ridge development.
