In this paper, we study numerical methods for a coupled Stokes-Darcy model. This model is composed by Stokes equations in the fluid domain and Darcy's law in the porous media domain, coupling together through certain interface conditions. By introducing a Lagrange multiplier, the coupled model is formed into a saddle point problem. A nonconforming mixed finite element method with nonmatching meshes is proposed to solve this coupled problem. The well-posedness of the discrete problem is proved. Moreover, we derive the a priori error estimates of the proposed finite element method. Numerical examples are also given to confirm the theoretical results.
