Resumen:
In order to reach a navigational depth of 45 feet during the entire tidal cycle, the most internal
section of the Access Channel to the Bahía Blanca harbour complex will be shortly dredged. At the outer end of
this section, an unusual field of large dunes occurs.Within this field, results show two different and well defined
zones characterized by particular dunes morphology each and a differing hydrodynamic profile, with lateral and
vertical variations in tidal currents velocity and direction. Dunes migration also shows differential migration
rate depending on the bed form size. Differences in speed and direction of tidal currents between both channel
sides are responsible for the dunes field formation. Such asymmetry is caused by the occurrence of hard to erode
materials cropping out at both channel flanks which generate a narrowing of the channel southward and by the
presence of a submarine bank northwards.
