2.3.1.2. Environmental Impacts of Dredging

Try these first

1. 1.

   What are contaminated sediments?

   Hint

   Think about sources of pollution in marine environments.

2. 2.

   What is resuspension in dredging?

   Hint

   Consider what happens during dredging activities.

3. 3.

   What is the primary concern with contaminated sediments?

   • They can improve water quality
   • They can spread pollutants
   • They have no impact

   Hint

   Think about what happens during dredging.

4. 4.

   Monitored Natural Recovery relies on which process?

   • True
   • False

   Hint

   Remember natural processes in the context of pollution.

5. 5.

   Design a remediation plan for a hypothetical contaminated sediment site located near a busy port. Include all necessary components and considerations, such as dredging methods, expected impacts, and mitigation strategies.

   Hint

   Consider the environmental impact of every decision in the plan.

6. 6.

   Create a comparative analysis of mechanical and hydraulic dredging approaches in terms of environmental impact and effectiveness in different scenarios.

   Hint

   Think about the context – what environment are we operating in?
