## ---- CemaNeige version
If \code{IsHyst = FALSE}, the original CemaNeige version from Valéry et al. (2014) is used. \cr
If \code{IsHyst = TRUE}, the CemaNeige version from Riboust et al. (2019) is used. Compared to the original version, this version of CemaNeige needs two more parameters and it includes a representation of the hysteretic relationship between the Snow Cover Area (SCA) and the Snow Water Equivalent (SWE) in the catchment. The hysteresis included in airGR is the Modified Linear hysteresis (LH*); it is represented on panel b) of Fig. 3 in Riboust et al. (2019). Riboust et al. (2019) advise to use the LH* version of CemaNeige with parameters calibrated using an objective function combining 75 \% of KGE calculated on discharge simulated from a rainfall-runoff model compared to observed discharge and 5 \% of KGE calculated on SCA on 5 CemaNeige elevation bands compared to satellite (e.g. MODIS) SCA (see Eq. (18), Table 3 and Fig. 6). Riboust et al. (2019)'s tests were realized with GR4J as the chosen rainfall-runoff model. \cr
If \code{InputsModel} parameter has been created for using a semi-distributed (SD) lag model (See \code{\link{CreateInputsModel}}), the parameter \code{isSD} should be set to \code{TRUE}.

Please note that if CemaNeige is used, and \code{ZInputs} is different than \code{HypsoData}, then precipitation and temperature are interpolated with the \code{DataAltiExtrapolation_Valery} function.
}
Users wanting to use a semi-distributed (SD) lag model should provide valid \code{Qupstream}, \code{LengthHydro}, and \code{BasinAreas} parameters. Each upstream sub-catchment is described by an upstream flow time series (one column in \code{Qupstream} matrix), a distance between the downstream outlet and the upstream inlet (one item in \code{LengthHydro}) and an area (one item in \code{BasinAreas}).
The order of the columns or of the items should be consistent for all these parameters. \code{BasinAreas} should contain one extra information (stored in the last item) which is the area of the downstream sub-catchment.
Upstream flows that are not related to a sub-catchment such as a release or withdraw spot are identified by an area equal to \code{NA} and an upstream flow expressed in m3/time step instead of mm/time step.
Please note that the use of SD lag model require to use the \code{\link{RunModel}} function instead of \code{\link{RunModel_GR4J}} or the other \code{RunModel_*} functions.
