Question 1

What is the main function of the mass transfer coefficient in contaminant transport?

  • To quantify sediment density
  • To relate concentration differences to transfer rates
  • To measure sediment depth

💡 Hint: Think about how substances move in relation to their concentrations.

Question 2

True or False: The error function is used to assess expected deviations in diffusion processes.

  • True
  • False

💡 Hint: Recall its primary functionality in handling diffusion equations.

Challenge Problems

Push your limits with challenges.

Question 1

Given a scenario with uniform contaminant distribution in sediment, calculate the expected flux at the sediment-water interface after 5 days using given mass transfer coefficients and initial concentration.

💡 Hint: Make sure to consider how time impacts concentration gradients in your calculations.

Question 2

Discuss how varying levels of turbulence in a river would influence the process of resuspension and subsequent water quality assessment.

💡 Hint: Think about how sediment dynamics change with water flow changes.
