The determination of the residual circulation is essential to the interpretation of the sedimentation pattern. The classical picture of the residual circulation in the Southern Bight could not explain the observation of mud deposition in front of the Belgian coast. Hence, a more refined model was built where, although the shear and the Reynolds stresses are approximated by dispersion terms, the tidal stress was explicitly calculated using a preliminary tidal model. It is shown that the new model predicts the existence of a residual gyre off the Belgian coast which, increasing the residence time of the water masses and in particular the entrained water from the Scheldt estuary, fully explains the observed sedimentation pattern.
