A practical procedure is outlined for determining wind-induced drift currents near the free surface, at all fetches, from a single wind-velocity measurement. The wind stress is scaled according to the Froude number and the momentum flux of the wind is considered to be partitioned between the wave drag and the momentum flux of the current. Some coefficients involved in the procedure are derived from the available data; further studies are suggested to refine the present estimation.
