“…Additionally, some piezometric data of the phreatic level evolution are available at certain locations of the Arnás catchment [16]. Both catchments have also been studied from a numerical perspective in the past, focusing on the calibration of the infiltration component of the model [18,19,5,6]. In [19] the influence of the computational mesh over the numerical runoff generation was studied, leading to an optimal choice which is the mesh used here.…”

Nowadays, the great power of modern computers allows to develop computational models able to deal with simulations of several coupled phenomena over detailed complex topography. An efficient and properly calibrated computational model represents a useful tool to provide insight into the catchment dynamics at hydrological and geomorphological levels. In addition, it allows to develop detailed risk management and conservation plans. In this work, we present a coupled surface-groundwater distributed flow model with hydrological (rainfall and infiltration) and geomorphological (suspended and bed load sediment transport) components. The coupled model is applied to well characterized experimental catchments that are used as realistic test cases. The calibration of the water flow model response to rainfall is performed by means of the fitting to experimental outlet hydrographs of the results supplied by a coupled formulation of 2D Shallow Water Equations and 2D Darcy's law for saturated porous media connected via suitable infiltration laws.
