Even as water flows over smooth sand there will be some disturbance. Water in contact with a non-eroding surface has zero velocity and so across an area of river to the sides or bottom there will be a gradient of current speed such that as it almost touches the substrate the speed is negligible. This is called the boundary effect or boundary layer.
