abstract = {<p style="text-align: justify;">In this work, we study numerical methods for a coupled fluid-porous media
flow model. The model consists of Stokes equations and Darcy&#39;s equations in two
neighboring subdomains, coupling together through certain interface conditions. The
weak form for the coupled model is of saddle point type. A mortar finite element
method is proposed to approximate the weak form of the coupled problem. In our
method, nonconforming Crouzeix-Raviart elements are applied in the fluid subdomain
and the lowest order Raviart-Thomas elements are applied in the porous media
subdomain; meshes in different subdomains are allowed to be nonmatching on the
common interface; interface conditions are weakly imposed via adding constraint in
the definition of the finite element space. The well-posedness of the discrete problem
and the optimal error estimate for the proposed method are established. Numerical
experiments are also given to confirm the theoretical results.</p>},
