The effects of shear on small particle motion close to a horizontal surface are described. These effects are then combined with those of turbulence for a complete description of particle dynamics near a stationary wall, yielding the conditions required for particle resuspension. Unstable particle motion depends on its initial velocity and distance from the wall. This is important for the study of particle resuspension from surfaces in turbulent flows, where the particles move inside viscous sublayer and is subject to both shear and turbulent effects.
