Energy dissipation by wave screens due to oblique wave incidence

A comprehensive experimental program was carried out to evaluate the variation in pressures on a vertical wall in the presence of single or double wave screens on its seaward side. The variation in pressures due to the obliqueness of the incident waves is studied. Tests were carried out with one screen as well as two screens for four different wave directions of 0°, 15°, 30° and 40°. It is observed that the pressure induced on the wall decreases with an increase in relative water depth. It is also observed that, with an increase in obliquity of the wave incidence the pressure induced on the wall gets reduced. © 2010 World Scientific Publishing Co. Pte. Ltd.
