Townley, L.R. (2000), Elizabeth River Recreational Waterway Study, Distribution of salinity in reservoir, prepared for EWL Sciences Pty Ltd, by Townley & Associates Pty Ltd, 20 pp., January

The overall goal of this study is to assess a number of potential environmental impacts in the context of the salinity distributions which would be expected to occur. This Section provides an analysis of the hydrology and hydrodynamics of the proposed reservoir, to provide that context.

The analysis requires a description of the physical system, in terms of its geometry and the climatic and water quality variables that drive the hydrology of the system. Appropriate data have been obtained and are described below.

The methods of analysis using hydrologic and hydrodynamic models are described in sufficient detail to give confidence to the results that follow.

Finally, model predictions are presented to ilustrate the spatial and temporal variations in salinity that are likley under several scenarios. The initial presmise is that it is desirable to pump seawater from East Arm into the reservoir, to maintain salinity at a sufficiently high level to assist in management of biting midges and mosquitoes. Possible operating rules are developed and discussed.
