Dredging Environmental Management Services

Sea transport is an important part of Western Australia’s economy. Our ports and harbours will generally from time to time require maintenance dredging to maintain shipping channels or capital dredging for expansion. If not managed correctly, dredging has the potential to alter turbidity levels, pH and/or nutrient levels of surrounding waters which may in turn result in environmental impacts. The assessment of re-use and/or disposal options of dredge spoil also requires appropriate analysis to ensure that material removed through dredging works is managed in accordance with appropriate State and Federal environmentalguidelines.

360 Environmental and Marine Monitoring

360 Environmental can offer a multi-disciplined team who can address contemporary marine monitoring requirements, meeting the needs of the Project and the expectations of the community, whilst delivering on excellent environmental outcomes. Studies can include: The marine component of the works mayinvolve:

• Hydrodynamic modelling e.g. Plume Dispersion Modelling
• Coastal Processes Investigations
• Baseline Studies - Marine Habitat Studies, Sediment Sampling, Benthic Habitat Mapping, Water Quality and Marine Fauna Surveys
• Dredge Monitoring Program and Dredge Environmental Management Plan
• Noise Management and Contamination Investigations.

Baseline monitoring has traditionally been undertaken using diver-based methods but these surveys havesignificant Health, Safety and Environment (HSE) challenges and are resource intensive. Our diver-free survey methods are appropriately designed to detect the relative change resulting from anthropogenicactivities.
