We study step wandering induced by the drift of adatoms in a conserved system. When steps are impermeable, in-phase wandering occurs with the step-down drift, The steps are unstable for long-wavelength fluctuations and the wavelength of the most unstable mode is determined by the competition between the drift and the step stiffness. When nonlinear effects are taken into account, the steps obey the same type of equation as that of the step wandering due to the Ehrlich-Schwoebel effect in growth without evaporation. We carry out Monte Carlo simulation and compare the results with the nonlinear evolution equation.
