Question 1.
What is the retardation factor?
Show hintHide hint
Think about how sediments react with contaminants.
Question 2.
Define flux in terms of sediment transport.
Show hintHide hint
Consider the flow of contaminants across a boundary.
3Question 3.
What does the retarding factor tell us about sediment transport?
- It increases contamination concentration
- It slows down contaminant movement
- It has no effect on transport
Show hintHide hint
Think about the meaning of the word 'retard' in this context.
4Question 4.
True or False: The boundary conditions must be specific to each location in the sediment.
- True
- False
Show hintHide hint
Recall the importance of defining limits in transport equations.
Question 5.
Given a sediment with varying concentrations in 3 layers, how would you approach calculating the total flux at the sediment-water interface?
Show hintHide hint
Consider how concentration and depth interact in your calculations.
Question 6.
Explain how varying sediment properties (like porosity and density) would influence the retardation factor and consequently transport dynamics.
Show hintHide hint
Link the properties with the transport rates directly.
