Challenge Problems
Push your limits with challenges.
Question 1
Consider a contaminated lake with an initial concentration of 200 mg/L of a contaminant. If the flux is initially at its highest level due to high concentration, describe how you would model the change in concentration at different times.
💡 Hint: Think of how the relationship between concentration and flux can change with time.
Question 2
Given the interplay between diffusion and convection in a sediment-water system, outline a monitoring strategy to assess the contaminant transport process effectively.
💡 Hint: Consider factors that can influence both diffusion and convection, such as weather events.
