Summary
An alternative approach to determination of the complex dissipation coefficients at the solid boundaries of a wave tank is suggested. The proposed method is based on the balance between the apparent energy consumption in the wall boundary layer and the full complex energy flux to this layer from the potential core. The present technique allows one to incorporate easily the dissipation in the nonlinear model describing the evolution of standing waves of finite amplitude in a rectangular tank. The relative importance of wavemaker dissipation in this case is discussed.
