Question 1.
What is diffusion in the context of sediment transport?
Show hintHide hint
Think about how contaminants move between sediment and water.
Question 2.
Define resuspension.
Show hintHide hint
What happens during a storm or high energy event?
3Question 3.
What is the primary transport process that occurs when substances move along a concentration gradient?
- Advection
- Resuspension
- Diffusion
- Bioturbation
Show hintHide hint
Remember: High to low concentration.
4Question 4.
True or False: Bioturbation only slows down sediment transport.
- True
- False
Show hintHide hint
Think about the role of organisms in the sediment.
Question 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.
Show hintHide hint
Consider how nutrients and contaminants interact in such scenarios.
Question 6.
Propose a model for sediment transport in a lake with significant bioturbation. What factors should be considered in your model?
Show hintHide hint
Think about how biological life alters sediment properties.
