Synopsis

A numerical model based on a Galerkin finite element solution of the one-dimensional salt transport equation is used to simulate the unsteady longitudinal distribution of salinity in the Tay Estuary. Tidal discharges are provided by the hydrodynamical equations of motion and continuity whose solution is coupled to that for the transport of salt. Dispersion coefficients used in the model are estimated with the aid of field data collected during a spring and neap tide. These coefficients are shown to vary with longitudinal position.
