p. 21 - 27 LES CUSPS ET LES COURANTS DE RIP SUR LA PLAGE D'AGIGEA INSTITUT Glicherie Caraivan L'Institut Roumain de Recherches Marines Constantza Abstract The morphologic and genetic particularities of cusps and current rip from the Agigea beach, and their dependence with hydrodynamic regime of the sea are described. The author find that the distance between the cusps (Y) is equal to the distance between the rip currents, and has value: Y=n ?/4, where ? is wave length of edge waves, and n is a number that may be from 1 to 4.
