%X A uniform potential flow past a slightly deformed porous circular cylinder inside a porous bed is discussed. The permeabilities of the porous bed and that of the cylinder are assumed to be different. On the surface of the deformed circular cylinder, continuity of pressure and continuity of normal velocities are used. The flow inside the two porous regions is represented as a viscous potential flow with the corresponding pressures related to the seepage velocities by Darcy's law. Flow fields have been plotted for various parameters like the permeability ratios, and the deformation parameters. The effect of these parameters on the volume flow coming inside the deformed cylinder is discussed. Velocity profiles for different values of the deformation parameter and permeability ratio are discussed using graphical illustrations.
