\details{
It is advised to run the GR5H model with an interception store (see Ficchi (2017) and Ficchi et al. (2019)) as it improves the consistency of the model fluxes and provides better performance. To do so, the \code{\link{Imax}} function allows to estimate the maximal capacity of the interception store, which can then be given to \code{\link{CreateRunOptions}}. \cr

For further details on the model, see the references section. \cr
For further details on the argument structures and initialisation options, see \code{\link{CreateRunOptions}}.

See \code{\link{RunModel_GR5J}} to look at the diagram of the hydrological model when no interception store is used.
