ABSTRACT: Research works on the coupling of incompressible surface flow with subsurface porous media flow arouse increasing interest recently. The coupled problems are typical multi-domain problems with multi-physics. Correspondingly, heterogeneous partial differential equations for modeling these problems are coupled together at the interface between two domains. We propose several decoupled algorithms so that numerical computations can be realized in parallel. Specifically, we investigate decoupled preconditioning techniques and two grid algorithms. Numerical examples and mathematical analysis are given to show that our algorithms are effective and efficient.
