online analysis of dissolved oxygen in a stream, stream pollution, water pollution, Victor Miguel Ponce


     online_do_sag_analysis:   Dissolved oxygen sag analysis



Rationale                                          Description


Differential equation for DO sag                       Ss = f(T)


Deoxygenation constant kd                 Oxygenation constant ko


INPUT DATA:

[Click on Calculate below to run in default mode without inputting any data].

Select:      [Choose SI or U.S. Customary units].

[Default: SI units; program resets to default units].

Deoxygenation constant kd (day-1):     
Leave blank to set default kd = 0.2

Oxygenation constant ko (day-1):     
Leave blank to set default ko = 0.6


[Saturation dissolved oxygen is at zero salinity and mean sea level].

Water temperature T (oC) [oF]:     
Leave blank to set default T = 20oC (T = 68oF)

Ratio of dissolved oxygen upstream to dissolved oxygen at saturation Os/Ss:     
Leave blank to set default Os/Ss = 0.9

Stream velocity v (m/s) [ft/s]:     
Leave blank to set default v = 1 m/s (v = 3.28 ft/s)
