English term or phrase: longshore transport

The average orientation of the shore is 190 degrees. Since the offshore wave direction is generally south-southwest (202.5 degrees) it can be expected that, on average, waves will approach the shoreline at a slightly oblique angle which would tend to drive longshore sand transport eastward

Déplacement le long du rivage de matières déposées sur le littoral (quelle que soit son acceptation, sa profondeur, ...) par les courants, les vagues, les vents... En l'absence de spécification sur la nature de ce qui est transporté, la dérive littorale concerne principalement l'eau. Par extension et abus de langage, l'expression a voulu aussi désigner les mouvements sédimentaires. Mais le sens premier demeure; il est préférable de parler de "courants de dérive" pour désigner les courants littoraux, et de "transport sédimentaire" pour parler des sédiments, quels qu'ils soient.(ν)

le flux sédimentaire

Explanation:
longshore drift (oceanography) = flux sédimentaire

Je pense qu'il s'agit du même concept, le sable est transporté sous l'effet des vagues et de la dispostion du terrain.
