Abstract

For many applications it is possible to reduce the wave motion in the protected area sufficiently using the submerged plate as a wave filter. The horizontal submerged plate, which hardly obstructs the cross-section of the flow, cannot be explained by the Wiegel approach at all. A strong pulsating flow opposite to the direction of the wave propagation originates beneath the plate during wave attack. New velocity measurements, carried out with an ultrasonic 3D-probe in the region below the plate, make it now possible to explain the principle much more in detail. They show that the flow phenomenon at the plate is very stable, the flow is nearly as strong if the region below the plate is partly closed.
