Two-dimensional slow viscous flow over a fence on a plane is investigated on the basis of Stokes approximation. A formal solution of the problem is obtained by solving the simultaneous Wiener-Hopf equations. The normal and shear forces and moment exerted on the fence are obtained as functions of $Θ_0$, the intersection angle of fence and the infinite plane. For the case of $Θ_0=75˚$, streamline pattern agrees well with that visualized by Taneda.
