In many applications free surface flow through rigid porous media has to be\nmodeled. Examples refer to coastal engineering applications as well as\ngeotechnical or biomedical applications. Albeit the frequent applications,\nslight inconsistencies in the formulation of the governing equations can be\nfound in the literature. The main goal of this paper is to identify these\ndifferences and provide a quantitative assessment of different approaches.\nFollowing a review of the different formulations, simulation results obtained\nfrom three alternative formulations are compared with experimental and\nnumerical data. Results obtained by 2D and 3D test cases indicate that the\npredictive differences returned by the different formulations remain small for\nmost applications, in particular for small porous Reynolds number ReP < 5000.\nThus it seems justified to select a formulation that supports an efficient\nalgorithm and coding structure.\n
