OBSERVATIONS AND MODEL SIMULATIONS OF A NEAR-SHORE TIDAL EDDY

Observations and model simulations have been made of a semi-permanent eddy that is created by the tidal currents in the Menai Straits. The eddy could be reproduced by a depth-averaged model provided that the non-linear advection terms, realistic bottom topography and a sufficiently low value of the horizontal eddy viscosity were included. Numerical simulations suggested that lateral stresses and the flow adjustment induced by variations in bottom depth were more important than the direct effects of bottom friction. The simulations clearly demonstrate the important role that near- shore eddies can play in the dispersion of waste from a coastal outfall.
