Abstract

The Water Board in Sydney constructed three deep ocean outfalls to replace existing shore-based effluent outfalls. An environmental monitoring program was established to investigate the effects of the new outfalls. As part of this program various remote sensing techniques were examined to provide input for biological and physical oceanographic studies of the coastal environment. One of the main objectives of the remote sensing program was to provide data for the verification of the outfall plume behaviour as predicted by 3D numerical models. The remote sensing techniques examined included satellite imagery in the visible and thermal infra-red regions, high frequency radar and airborne scanner data. The results provided a synoptic view of surface or near-surface features and when combi
