Question 1.
Define resuspension.
Show hintHide hint
Think about what happens to sediments when water flow increases.
Question 2.
What does TSS stand for?
Show hintHide hint
It's a measurement related to the particles in the water.
3Question 3.
What is resuspension?
- A process of sediment settling
- A process of sediment being stirred back into water
- A type of water filtration
Show hintHide hint
Consider what happens when water turbulence increases.
4Question 4.
True or False: Resuspended sediments can contain harmful contaminants.
- True
- False
Show hintHide hint
Think about the contaminants that could be contained in sediments.
Question 5.
Given a sediment concentration of 100 mg/g and a TSS of 2000 mg/L, calculate the potential contaminant concentration in the water assuming all suspended solids are evenly distributed.
Show hintHide hint
Think about how the concentration of suspended solids relates to the mass of contaminants.
Question 6.
Explain the potential ecological ramifications of increased sediment resuspension due to human activities like dredging.
Show hintHide hint
Consider both chemical and biological impacts.
