4. For the Red River of the North homework problem, suppose reach 1 also had a reach-wise uniform
sediment oxygen demand, S b , of 0.35 mg/L/day. Compute the dissolved oxygen concentration at the end
of each reach.
5. It takes 18 days for 99.9 percent of the E. Coli bacteria to be removed (die, settle out) in the Ohio
River. What is the appropriate first-order rate constant to describe this data? What can you conclude about
the adequacy of the first-order assumption in this case?
