Wave driven force on a deformable but inextensible thin sheet is investigated analytically by taking into account the boundary layer beneath the sheet. Wave tank experiments are carried out to verify the theoretical predictions. Theoretical prediction of the drift force, drift velocity, and wave attenuation by the sheet are made. It is found that the drift velocity of a contaminated free surface is much greater than that of a clean free surface, and increase in the drift velocity is greater for the greater shear stress on the interface of the viscous surface layer and the water below. The theoretical and experimental results are found in good agreement.
