If the Salmon River temperature in Problem 7-33 decreases to 12°C, will the discharge from Big Bear reduce the DO in the river below 5.00 mg/L at a distance of 5.79 km downstream? Note: You must calculate a new temperature of the mixed river water and wastewater, then correct ka and k, of the river only.
