A water quality model for Westernport Bay

The object of this project was to develop a Water Quality Model for Westernport Bay. The literature describing the dispersion process was critically examined and it was concluded that the Lagrangian des- scription is a more direct representation of the actual dispersion process. Therefore the Lagrangian random walk model was developed to model the transport of conservative wastes in turbulent flow. A variety of field experiments were carried out to assess the different process causing mixing in Westernport Bay, and their relative importance. Computer programs were developed for a hydrodynamic and random walk transport model. When calibration and verification have been completed it is believed that the Water Quality Model described herein will be a useful tool in representing waste movement in Westernport Bay
