Question 1

What does the semi-infinite boundary condition assume?

  • Concentrations remain constant at all points
  • Concentrations decrease with depth
  • Concentrations remain constant far from the boundary

💡 Hint: Think about the definition of 'infinity' in relation to depth.

Question 2

Is the retardation factor important in contaminant transport modeling?

  • True
  • False

💡 Hint: Recall how delay affects contaminant movement.

Challenge Problems

Push your limits with challenges.

Question 1

For a sediment with an initial contaminant concentration of 200 mg/kg and a diffusion coefficient of 0.01 m²/s, calculate the concentration at a depth of 5 cm after 2 hours. Assume a semi-infinite model.

💡 Hint: Consider how time and depth influence the diffusion of contaminants.

Question 2

You have a sediment core with varying concentrations from top to bottom. Discuss how you would mathematically model this scenario given the initial conditions and boundary constraints.

💡 Hint: Reflect on using numerical methods to tackle spatially variable concentrations.
