Residual Currents in the Western Dutch Wadden Sea
It is shown by means of a numerical model of the western Dutch Wadden Sea that the residual current velocity field cocnsists of a throughflow from one tidal basin to another and a field of residual eddies. The first can be explained by the residual momentum balance which gives the driving force of the throughflow in terms of the tidal stress. The latter is more easily understood from the vorticity balance in which bottom frictional generation and damping of vorticity, together with vortex stretching, explain most of the observed features. Near the inlets the rediual eddy pattern has the shape of a highly distorted vorticity quadrupole.
