The maximum ebb current are registered along different sectors the main estuarine channel where the maximum current is about 1.
In the southern Bay area, this current meets the opposite inertial ebb current of the mixed waters from the inner estuary that are extruded from the main channel.
2008), as well as during the same tidal cycle with less saline ebb current surface and marine current flows.
Along the tidal cycle, a general levorotatory circulation acts throughout the estuary, the current flows along the left side, however the ebb current flows along the right.
During normal ebb currents most of the tidal energy is dissipated across the closure.
Anticlockwise rotation only forms in the Mouth and the outer part of the Bay and the remaining areas present only unidirectional ebb currents.
In the outer inlet, a deep scour forms to replace the mouth bar where the strong ebb currents are dissipated.
In this way, the morphology of the wave fronts was modified by the ebb current and, as a consequence, also their direction of propagation.
In the Oka estuary, waves approach mainly from the northwest and force the ebb current to move to the western margin where the wave heights are smaller.
3) disappeared between July and August 2005 due to both the landward migration of the intertidal sand ridges and to the sand transport produced by the ebb currents.
Sediment accumulated on the proximal area of the sand bar, reduced the inlet cross-section and thus increased the mean velocity of the ebb currents.
