DESCRIPTION

METHODOLOGY

where

c = DO concentration, [mg/L]
co = DO concentration at x = 0, [mg/L]
Kd = Effective BOD deoxygenation rate [1/day]
Ka = DO reaeration coefficient [1/day]
Kr = Overall BOD loss rate [1/day]
x = Flow distance [m]
U = Flow velocity [m/s]
Lo = Initial BOD concentration [mg/L]
cs = DO saturation concentration [mg/L]

DO = Dissolved Oxygen
BOD = Biochemical Oxygen Demand
