SIM is
implemented using the three layered force–restore version (Boone
et al., 1999) with the 3-layer snow scheme of Boone and Etchevers
(2001). The version used in this study (Quintana Seguí et al., 2009)
also includes an exponential profile of hydraulic conductivity to
better reproduce the dynamics of water in the soil (Decharme
et al., 2006).
