A three dimensional unsteady convection flow of a viscous incompressible fluid through a highly porous medium with mass transfer effects bounded by an infinite inclined porous plate is analyzed. Assuming the free stream velocity to be uniform, approximate solutions are obtained and the effects of the following: the magnetic field (M), permeability parameter (K0), thermal Grashof number (Gr), mass Grashof number (Gc), Prandtl number (Pr), Schmidt number (Sc) and angle of inclination ( )on the velocity field, the temperature field, skin friction and the rate of heat transfer are discussed with the help of graphs. It is observed that an increase in K0 increases the skin friction but decreases the Nusselt number near the plate which increases as we move away from the plate whereas increase in M decreases the skin friction as well as the Nusselt number near the plate.
