Abstract
    We present a 3D continuous-discontinuous Galerkin subsurface-flow model that will be integrated within the hydrodynamical model SLIM. The model is based on mixed form of Richards equation that takes the retention curve as a constraint on the volumetric water content. A flexible continuous-discontinuous Galerkin discretization is proposed. The model is shown to be exactly mass-conservative and compares well with the state-of-the-art model Hydrus.
