Data Input
In order to input the required information for this pollutant into the Water Quality model, the user needs to make sure that the Tab Adsorbed Phosphorous appears in the WQ General Tab (please follow the description on the page Preparing a Water Quality Datafile for this). Then the user needs to select the Tab Adsorded Phosphorous and type in the necessary information for this pollutant in the fields which are shown on this Tab. Alternatively the necessary information for this pollutant can be typed in the .con file opened in a Textpad editor in the datafile format mentioned below.
Datafile Format
Line 1 ADSORBED PHOSPHORUS
Line 2 phk, alphap, phmax, adlan (4f10.0)
Where:
ADSORBED PHOSPHORUS = keyword
Phk= Adsorption rate at 20C (day-1)
Alphap= temperature dependence factor
Phmax= saturation adsorption ratio of phosphate to mud
adlan= half-saturation constant for Langmuir isotherm (mg/l).
