Dissolved Oxygen Analysis Modeling

This applet is a DO sag generator. It based on the Streeter and Phelps equation to calculate the impact of a single point source.


C = DO concentration (mg/L)
C0 = DO concentration at x = 0 (mg/L)
Cs = DO saturation concentration (mg/L)
kd = Deoxygenation rate (1/day)
ka = Reaeration coefficient (1/day)
kr = Overall reaction rate (1/day)
X = Flow distance (m)
U = Flow velocity (m/s)
L0 = Ultimate BOD (mg/L)
