Challenge Problems
Push your limits with challenges.
Question 1
A river is flowing with a velocity of 2 m/s carrying a pollutant downstream. If the concentration of the pollutant is 5 mg/L, calculate the approximate total flux of pollution in the river flow.
💡 Hint: Multiply the velocity by concentration to find the flux.
Question 2
Discuss the potential impacts of changing groundwater velocities due to increased rainfall on pollutant transport in a saturated zone.
💡 Hint: Consider how changes to flow could alter the mass transport processes.
