\title{Run with the provided hydrological model function}


\description{
Function which performs a single model run with the provided function over the selected period.
}


\usage{
RunModel(InputsModel, RunOptions, Param, FUN_MOD, ...)
%
%\method{[}{OutputsModel}(x, i)
}


\arguments{
\item{InputsModel}{[object of class \emph{InputsModel}] see \code{\link{CreateInputsModel}} for details}

\item{RunOptions}{[object of class \emph{RunOptions}] see \code{\link{CreateRunOptions}} for details}

\item{Param}{[numeric] vector of model parameters (See details for SD lag model)}

\item{FUN_MOD}{[function] hydrological model function (e.g. \code{\link{RunModel_GR4J}}, \code{\link{RunModel_CemaNeigeGR4J}})}

\item{...}{(optional) arguments to pass to \code{FUN_MOD}}
%
%\item{x}{[InputsModel] object of class InputsModel}
%
%\item{i}{[integer] of the indices to subset a time series or [character] names of the elements to extract}
}



\value{
[list] see \code{\link{RunModel_GR4J}} or \code{\link{RunModel_CemaNeigeGR4J}} for details.

If \code{InputsModel} parameter has been created for using a semi-distributed (SD) lag model (See \code{\link{CreateInputsModel}}), the list value contains an extra item named \code{QsimDown} which is a numeric series of simulated discharge [mm/time step] related to the run-off contribution of the downstream sub-catchment.
}

\details{
If \code{InputsModel} parameter has been created for using a semi-distributed (SD) lag model (See \code{\link{CreateInputsModel}}), the first item of \code{Param} parameter should contain a constant lag parameter expressed as a velocity in m/s, parameters for the hydrological model are then shift one position to the right.
