A can of a degrading chemical has spilled into a small pond. List the data you would need to gather to calculate the concentration of pollutant in the stream leaving the pond using the mass balance technique. Collecting data is expensive!
What model would you use to estimate the concentration of a pollutant in a river?
What assumptions are inherent in this model? List at least two.
How would you simplify your model equation if the pollutant were a conservative substance?
How would you simplify your model equation if the system were at the steady state?
How would you simplify your model equation if the pollutant were spilled as an impulse injection?
