A theoretical study is made of the sedimentation of a small sphere in a viscousfluid bounded by horizontal and vertical walls. The analysis is based on thequasi-steady equations of motion, and the first-order wall effect is taken intoaccount. The trajectory of the particle slightly deviates from the vertical line,the magnitude of which is determined by the angular position of the sphere.When the ensemble of spheres with randomly distributed initial positions isconsidered, the spheres which originally lay at a height h are found most frequentlyat the distance 0.591 h from the side wall.
