Challenge Problems
Push your limits with advanced challenges
A river section has an inflow of 20 mg/L from a tributary and an outflow of 15 mg/L after a mixing distance. The concentration in the middle of the river section is measured. If the section's volume is not constant, how would you adjust your box model's assumptions for accurate predictions?
💡 Hint: Think about how variable inflows affect local conditions.
If a lake experiences a rise in pollutant concentration due to agricultural runoff, how do you apply the mass balance equations to predict future concentrations?
💡 Hint: Observe how changing inflows could affect overall mass balance.
