The geomorphology and historical evolution of an area located offshore Bahía Blanca Estuary in Argentina is analyzed. The area is conformed by subtidal sand banks and submarine channels with an almost parallel disposition. As sand banks have their sides dominated by opposite tidal currents, they evolve to zig-zag configuration and migrate eastward, in the direction of the navigation channel of Bahía Blanca Harbor Complex. More than 12 years ago major morphological modifications occurred at an internal channel mouth, which indirectly have arrested the evolution of the outer bank. At present, such beneficial influence would has almost finished, and a rapid sedimentation has started in the only access channel to the largest and deepest harbor of Argentina.
