dc.description.abstractThis paper reports on mathematical model developed to simulate salinity intrusion in coastal waterways in the south eastern coastlands of the Gold Coast (Australia) to neutralize acidity caused by pyrite oxidation. The model was used to predict the effect of salinity intrusion upstream of existing floodgates. Predictions of the model compared favourably with the field results. Instrusion of saline water can increase the pH of the upland water from 2.4 to 6.5, while the salt levels remain low enough so that it is not of concern to the landholders. Based on the computer predictions and experimental observations, it was concluded that the Nerang river flood mitigation system ought to be redesigned to allow for controlled tidal water intrusion upland of the floodgates to neutralize acid leached from groundwater. Such a structure would have to be constructed and installed in the creeks replacing existing one way floodgates thereby allowing the flow of saline water upland during inland tidal periods. In this manner, the saline creek water can neutralize much of the acidic water stored upland of the floodgates thereby reducing the ill-effect on fish and other estuarine communities and their habitats downstream following heavy rainfalls. Dear Colleague, All papers published in the Wessex Institute of Technology conference proceedings are subject to peer review. This review process is carried out by the conference chairmen and members of the International Scientific Advisory Committee (ISAC). The names of the ISAC are published in the front of each conference book and the names and affiliations of the committee for each conference are published on our website, The review process takes place at the abstract stage and again at the final paper stage. At either stage the authors may be required to alter his/her paper in accordance with the reviewer's comments and any alterations are also subject to review. Coverage of WIT conference proceedings appears regularly in a number of publications, including Applied Mechanics Reviews (AMR); Engineering Index and related publications from Elsevier Engineering Information Inc; INSPEC (IEE); Mathematical Reviews: Scitech Book News; ISI's Index to Scientific and Technical Proceedings, Index of Scientific Book Contents, Index to Social Science and Humanities Proceedings and Current Contents; and Various Cambridge Scientific Abstracts publications. Proceedings are also listed in the Directory of Published Proceedings.
