The steady flow in a parallel plate channel rotating with an angular velocity Ω and bounded below by a permeable bed is analysed under the effect of buoyancy force. On the porous bed the boundary condition of Beavers and Joseph is applied and an exact solution of the governing equations is found. The solution in dimensionless form contains four parameters: The permeability parameterσ2, the Grashof numberG, the rotation parameterK2 and a dimensionless constantα. The effects of these parameters, specially,σ2, G andK2, on the slip velocities and velocity distributions are studied. For largeK2, there arise thin boundary layers on the walls of the channel.
