【 摘 要 】

This paper presents a numerical model computing sea-bed evolution due to longshore current s, which has been developed at the Laboratoire National d'Hydraulique. This model has been applied to a schematic semi-circular bay. The computation of sand sea-bed modifications reveals two main tendencies ; a marked accretion in the "up-stream" zone of the bay and a marked erosion in the "down-stream" zone of the bay, as far as longshore currents are concerned.
