\title{Calculate initial predicted environmental concentrations in surface water due to drainage using the UK method}
\usage{
PEC_sw_drainage_UK(rate, interception = 0, Koc,
latest_application = NULL, soil_DT50 = NULL, model = NULL,
model_parms = NULL)
}
\arguments{
\item{rate}{Application rate in g/ha}
\item{interception}{The fraction of the application rate that does not reach the soil}
\item{Koc}{The sorption coefficient normalised to organic carbon in L/kg}
\item{latest_application}{Latest application date, formatted as e.g. "01 July"}
\item{soil_DT50}{Soil degradation half-life, if SFO kinetics are to be used}
\item{model}{The soil degradation model to be used. Either one of "FOMC",
"DFOP", "HS", or "IORE", or an mkinmod object}
\item{model_parms}{A named numeric vector containing the model parameters}
}
\value{
The predicted concentration in surface water in µg/L
}
\description{
This implements the method specified in the UK data requirements handbook and was checked against the spreadsheet
published on the CRC website
