We investigate the Riemann Problem for a shallow water model with porosityand terrain data. Based on recent results on the local existence, we build thesolution in the large settings (the magnitude of the jump in the initial datais not supposed to be ``small enough''). One difficulty for the extendedsolution arises from the double degeneracy of the hyperbolic system describingthe model. Another difficulty is given by the fact that the construction of thesolution assumes solving an equation which has no global solution. Finally, wepresent some cases to illustrate the existence and non-existence of thesolution.
