• We study experimentally the effects of different reflective conditions on momentum transfer in water waves. • A theoretical model is also derived considering the reflection coefficient and the phase shift. • The theoretical model is applied to quantify the spatial variation of velocity covariance and mean water level. • Wave shear stress, mean water level and principal wave tensor stresses are measured and compared with theory. • Results show that the proposed model provides an adequate evaluation of the quantities involved.
