Abstract: A wave tank and a wave generator was developed in stages in the laboratory to obtain different types of waves, wave breakers and currents. Tests on movement of sand were carried out using actual beach sand comprising heavy minerals of a wider range of grain sizes under pure waves, currents and a combination of waves and currents. It was found that the transportation and deposition of sand uniformly over a stretch of artificial beach is caused neither by pure waves nor by pure currents but by a combination of waves and currents.
