This data is from Walker and Kadlec, "A Model for Simulating Phosphorus Concentrations in Waters & Soils Downstream of Everglades Stormwater Treatment Areas", prepared for US Dept of the Interior, August 1996.

`case.number`

Index value unique for each case

`STA.Name`

The name of the Stormwater Treatment Area (STA) where this data originated.

`Receiving.Area`

The area which this STA discharges.

`Start.Discharge`

The year which this particular STA began discharge operations.

`STA.outflow.TPconc`

Outflow total phosphorus concentration (in ug L-1; mirograms per liter) for this STA.

`STA.outflow.vol`

Annual outflow discharge volume (in x1000 Acre-Feet Year-1) for this STA.

`FlowPath.width`

The width of the downstream flow path (in kilometers).

`Hydroperiod`

Average hydroperiod (time above ground surface) of the downstream system (in percent).

`Soil.Depth`

Depth of soil (in centimeters).

`Soil.BulkDensity.initial`

The initial bulk density prior to dicharge of the soil downstream of the system (in g cm-3).

`Soil.TPConc.initial`

The initial total phosphorus concentration of soil prior to discharge downstream of the system (in mg kg-1).

`Vertical.soilTPGradient.initial`

The soil total phosphorus concentration gradient prior to dischage downstream of the system (in mg cm-3 cm-1).

`Soil.BulkDensity.final`

The final bulk density after dischage of the soil downstream of the system (in g cm-3).

`PSettlingRate`

The phosphorus settling rate estimated from steady-state conditions (m Year-1).

`P.AtmoDep`

Phosphorus atmospheric depostition loading rate (in mg m-2 Year-1).

`Rainfall`

Annual accumulated rainfall estimate (m Year-1).

`ET Annual`

evapotranspiration estimate (m Year-1).
