Formatted abstract

A field and mathematical model study of the Brisbane River estuary is conducted in order to investigate trends in the water quality. Automatic recording field stations were designed and constructed, and collected field data used in a one-dimensional channel and node model to simulate prototype behaviour. Several alterations to the model have been made. 

Field data parameters comprise temperature, conductivity and dissolved oxygen. The model is used to first determine the dispersion characteristics using salinity data. Dissolved oxygen (i) is then modelled using the calculated dispersion together with previously accepted values for the re-aeration and decay coefficients. From the dissolved oxygen simulation the biochemical oxygen demand distribution for the river system is deduced.
