6. Complexity of Sediment Transport

Try these first

1. 1.

   What is diffusion in the context of sediment transport?

   Hint

   Think about how contaminants move between sediment and water.

2. 2.

   Define resuspension.

   Hint

   What happens during a storm or high energy event?

3. 3.

   What is the primary transport process that occurs when substances move along a concentration gradient?

   • Advection
   • Resuspension
   • Diffusion
   • Bioturbation

   Hint

   Remember: High to low concentration.

4. 4.

   True or False: Bioturbation only slows down sediment transport.

   • True
   • False

   Hint

   Think about the role of organisms in the sediment.

5. 5.

   Analyze a case study where high sediment resuspension is observed during a flooding event. Discuss how it may affect sediment quality and water health.

   Hint

   Consider how nutrients and contaminants interact in such scenarios.

6. 6.

   Propose a model for sediment transport in a lake with significant bioturbation. What factors should be considered in your model?

   Hint

   Think about how biological life alters sediment properties.
