Challenge Problems
Push your limits with advanced challenges
Given a sediment layer with an initial contaminant concentration of 500 mg/kg and a mass transfer coefficient of 2.3 m/yr, calculate the expected flux at the sediment-water interface after 30 days using derived equations.
💡 Hint: Refer back to the relationship between initial concentration and boundary conditions.
Discuss how the dynamics of resuspension would change in an environment with varying rainfall patterns, and what implications this has for contaminant levels downstream.
💡 Hint: Consider seasonal changes and impacts on water flow.
