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).

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).
