摘要：The exact velocity distribution for the flow of viscous incompressible fluid in an inclined channel with naturally permeable bed has been obtained by using the Laplace transform and the Finite Fourier Sine transform technique. It has been assumed that (i) the fluid flows in the steady state for t < 0, (ii) unsteady state occurs at t > 0, and (iii) unsteady state motion is influenced by time dependent pressure gradient.
