Question 1.
What is the primary purpose of using a transport model?
Show hintHide hint
Consider the behavior of substances in soils and water.
Question 2.
Define 'retardation factor' in simple terms.
Show hintHide hint
Think about speed bumps for contaminants.
3Question 3.
What does a 'transport model' help to predict?
- Movement of air
- Movement of contaminants
- Soil moisture content
Show hintHide hint
Think about pollutants in water.
4Question 4.
True or False: The retardation factor influences the speed at which a contaminant moves.
- True
- False
Show hintHide hint
Remember speed variations due to friction.
Question 5.
You suspect that contaminants are unevenly distributed in a sediment sample. Describe a sampling strategy you would use to characterize the contaminant distribution effectively.
Show hintHide hint
Consider how to achieve an accurate representation.
Question 6.
How would increasing the retardation factor in a model change the estimated time for contaminants to reach the water table from a sediment site?
Show hintHide hint
Think about how speed and time are related.
