Challenge Problems
Push your limits with challenges.
Question 1
Given a pollution incident where a substance has a concentration of 50 mg/L in sediment, calculate the expected flux into water if the mass transfer coefficient is 0.1 m/s.
💡 Hint: Consider the mass transfer model you've learned.
Question 2
A river's flow rate increases due to a storm. Discuss how this might affect the contaminants' behavior in the sediments and the surrounding environment.
💡 Hint: Think about how turbulence impacts sediment and mass transfer.
