Question 1
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.
Question 2
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.
