Resumen:
Swash generated by small waves has been found to be powerful enough to move largegravels on a sandy beach. To analyze the energy of the swash during a period of effectivegravel transport, swash on a mixed gravel-sand beach where studied by direct measurementwith and ADV and filmed with video camera from a tower located near the study area. Eventhough waves were of the order of 25 cm in height, they generated conditions large enoughto transport all the gravels within the camera field of vision. PIV estimations from the swashshows that the main orientation of the uprush is directly proportional to the angle of wavebreaking. Mean velocities estimated from the PIV was from 22 to 43 cm s-1 for the swashand 24 to 46 cm s-1 for the backwash which are of the same order than those measured byADV.
