WAMSI 2 - DREDGING NODE - PROJECT 4.3 Estimating sediment deposition fields around dredging activities

The objective of WAMSI DREDGING SCIENCE NODE Project 4.3 was to better understand the relationship between TSS and the orbital motion of waves using the instrumentation used during the Gorgon dredging program, at multiple sites using the baseline (pre-dredging) data and then during the dredging program. Specifically, the objective was to predict TSS levels based on the orbital velocity of waves and to identify periods where the measured TSS levels are higher than the modelled data predicts and which therefore may indicate turbidity caused by dredging or spoil disposal and which could represent periods of high sediment deposition. The information from the sediment deposition sensor can then be used to verify periods of high(er) sediment deposition..Data is in the form of a report, which is a secured (printable, non-editable), searchable, Portable Document Format (PDF) showing the results of the analyses.
