Abstract. The article considers pulse flows of a viscous fluid in a flat channel with permeable walls. Here we consider a long channel, since its ratio of width to length is quite small. The ratio of lateral velocity to longitudinal velocity and the Reynolds number are also considered to be small. Under such conditions, the Navier-Stokes equations are linearized and the necessary boundary conditions are formulated. When solving the problem, the necessary calculation formulas were found and research was carried out.

Keywords: Viscous, flat channel, pulse, permeable wall, incompressible.
