Conceptual model of a coupled surface-subsurface hydrology model and its integration within a DA and machine learning scheme to assimilate ground based measurements (geophysical tomography), plant and atmospheric measurements from RS. The soil parameters model is calibrated during an infiltration event or directly from time lapse ERT observations. Is(t) represent the partitionning of the rain from the tree canopy and the effect of stemflow, Ks1 to Ks3 are the soil hydraulic conductivities that plays a key role in water infiltration rate and that are unknowns model parameters that are inverted (infered during the DA process), RWU is the Root Water Uptake contributing to water use by the vegetation and transpirated.
