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 Imax function allows to estimate the maximal capacity of the interception store, which can then be given to CreateRunOptions.

For further details on the model, see the references section.
For further details on the argument structures and initialisation options, see CreateRunOptions.

See RunModel_GR5J to look at the diagram of the hydrological model when no interception store is used.
