Hall effects on hydromagnetic flow and heat transfer in a porous channel have been investigated. Constitutive equations of continuity, momentum and energy have been developed under the physical situations of the problem. Solving such equations, expressions for velocity, temperature, skin-frictions and rates of heat transfer including magnetic induction components have been obtained. The behaviours of MHD flow and temperature are shown by graphs and those of shear stresses and Nusselt Numbers are exhibited by tables. The heat transfer characteristics of the flow taking viscous and Joulean dissipation into account have also been studied. It is observed that the Hall parameter and the permeability factor influence the flow patterns appreciably
