- True
- False
Show hintHide hint
Recall how we previously discussed their importance.
Question 5.
Given a sediment concentration and a diffusion coefficient, calculate the expected concentration of contaminants after a specified time using the error function.
Show hintHide hint
Use the specified time to adjust parameters in your calculations.
Question 6.
Discuss how different boundary conditions could alter the outcomes of contaminant transport predictions in an environmental model.
Show hintHide hint
Think about the physical changes in the environment and their influence on sediment transport.
