Hydrodynamical equations show that these movements are more coupled in the coastal zone than in deep ocean. This characteristic is the result of current intensity, spatial gradients and bottom topography (depth). In the coastal environment tidal flow must be taken into account to study dynamic processes. The tide is not only an alternative movement but is the inducer of a long term current: the residual current. The author uses a bidimensional model to study currents from the depth and vertical structure of residual currents by the effect of density variations. Y1 - 1985/01/24 CY - La Baie de Seine.
