Usage
PEC_sw_drainage_UK(rate, interception = 0, Koc, latest_application = NULL, soil_DT50 = NULL, model = NULL, model_parms = NULL)
Arguments
- rate
- Application rate in g/ha
- interception
- The fraction of the application rate that does not reach the soil
- Koc
- The sorption coefficient normalised to organic carbon in L/kg
- latest_application
- Latest application date, formatted as e.g. "01 July"
- soil_DT50
- Soil degradation half-life, if SFO kinetics are to be used
- model
- The soil degradation model to be used. Either one of "FOMC",
"DFOP", "HS", or "IORE", or an mkinmod object
- model_parms
- A named numeric vector containing the model parameters
Value
The predicted concentration in surface water in µg/L
