Abstract

Finite element technique is used to model the concentration distribution of a reactive pollutant in the Tay estuary, Scotland. Considering the low concentrations of the pollutants which inevitably results from the mixing of relatively small amounts of contaminants with a large body of water the chemical reaction is modelled using first order kinetics. Tidal propagation within the Tay flow channel is characterised by significant phase lag between the mouth and interior reaches of the estuary. This results in continuous variations of the flow channel boundary during flood and ebb. To include this important feature in the model the shallow water equations representing the tidal flow in the Tay are solved in an Eulerian framework using the volume of fluid (VOF) approach. The simulated results are evaluated for theoretical and experimental consistency.
