Water quality, plume modelling and tracking before and during dredging in Mermaid Sound, Dampier W.A.

A water quality monitoring program established to coincide with the Mermaid Sound dredging projects in 2004 for assessed turbidity, suspended sediments and other parameters (Dissolved Oxygen, pH, Temperature, Salinity) every three days to start then weekly.To assist in locating monitoring sites - a model of sediment transport was developed. Also throughout the dredging program aerial surveys of the dredging location, monitoring locations and surrounding areas were undertaken on a weekly basis. They were flown of the same day as the water monitoring trip to allow for cross-referencing of visual observations and actual data.2004年为配合美人鱼水道（Mermaid Sound）疏浚工程而设立的水质监测项目，初期每3天对浊度（turbidity）、悬浮泥沙（suspended sediments）及其他参数（溶解氧（Dissolved Oxygen）、pH值、水温（Temperature）、盐度（Salinity））开展监测，后续调整为每周1次。为辅助确定监测点位，项目组开发了泥沙输运模型。此外，在整个疏浚工程实施期间，项目组每周对疏浚作业区、监测点位及周边区域开展航空勘测，所有航空勘测均与水质监测采样在同一天进行，以便实现目视观测结果与实测数据的交叉比对。
