Etudes expérimentales des profils cross-shore de plages sableuses

The main objectives of this study are on one end to test with a physical model the concept of equilibrium beach profile for a wave climate. Our experiments were conducted in the sedimentary LEGI wave-flume. We were able to identify eight wave climates leading to an equilibrium. Equilibrium profiles have been sorted according to their Dean number. On the other end, the evolution of profiles correctly reproduces the different scenarios observed in nature, such as erosion and sediment accretion at the shore and bar migrations.
