| By taking into account salinity measurements and consequently mean residence time, current measurements, tidal computation with a 2-D model and wind induced currents provided by a 3-D model, a global diagram of residual flow in Seine Bay is given. Main patterns are exhibited: density currents in the eastern part of the bay, off the Seine Estuary, wind induced circulation, especially along the coast and over the Channels, and tidal residual patterns induced by topography. |

| The movement of water particles in the ocean and littoral zone can be thought of as the result of elementary components superimposed, of which tidal flow is the main factor. 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. |
