Challenge Problems
Push your limits with advanced challenges
Given a river segment with an inflow contaminant concentration of 100 mg/L and an outflow concentration of 80 mg/L, along with a constant sediment transfer rate, develop a mass balance equation using the box model.
💡 Hint: Balance the input and output considering sediment transfer.
Analyze how introducing a chemical with a higher molecular weight than water into a river will affect the rate of diffusion and overall water quality.
💡 Hint: Reflect on how size affects movement through water.
