        In this paper, we discussed the Run up flow of an incompressible viscoelastic Rivlin-Ericksen fluid through a parallel plate channel bounded by a sparsely packed porous bed subjected to a traverse magnetic field. The velocity in both clean fluid as well as porous zones, the stresses and the mass flux are have been evaluated and their behavior has been computationally discussed for variations in the governing parameters.

Keywords: Run up flow, Visco elasticity, Brinkman equation, Newtonian fluid.
