When a fluid is in periodic wave motion, the particles are carried by a varying velocity field. The location of a particle varies as does the immediate velocity field. Fluid particles may have a net mean drift even if the local velocity field has zero mean this is the case in irrotational gravity waves. In viscous fluid, wave-induced Reynolds stress imparts steady momentum to the fluid a steady shear is the set up to balance it, hence a further mean velocity field results. The sum of these two steady currents provides the total drift by which a fluid particle migrates, i.e. mass transport velocity. This report is a description of theoretical and experimental aspects of mass transport by waves. Part I reviews basic assumptions of existing theories. Part II checks and evaluates theoretical deductions in Part I. Author
