Port Phillip & Westernport Groundwater Flow Systems (2004)

Eighteen Groundwater Flow Systems have been delineated in the Port Phillip and Westernport region - based on the model put forward by the National Land and Water Resources Audit. Consensus on the flow systems was an outcome of a three-day workshop held in October 2003, and subsequent discussions with regional experts.

This report was prepared by Peter Dahlhaus (Dahlhaus Environmental Geology Pty Ltd), David Heislers (Department of Primary Industries, Bendigo), Darrell Brewin (Darrell Brewin and Associates), John Leonard (John Leonard Consulting Services Pty Ltd), Phil Dyson (Phil Dyson and Associates Pty Ltd) and Don Cherry (Department of Primary Industries, Bendigo) for the Port Phillip and Westernport Catchment Management Authority.
