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.

WAMSI疏浚科学节点项目4.3的目标是，利用高更（Gorgon）疏浚项目期间所用的仪器，通过多个站点的基线（疏浚前）数据及疏浚项目期间的数据，深入理解总悬浮固体（Total Suspended Solids，TSS）与波浪轨道运动之间的关系。具体而言，该目标旨在基于波浪轨道速度预测TSS浓度，并识别实测TSS浓度高于模型数据预测值的时段——这些时段可能指示由疏浚或弃土处置引起的浑浊，且可能代表高沉积物沉积时段。沉积物沉积传感器的信息可用于验证高（或较高）沉积物沉积的时段。
