Effect of wave screens on the dynamic pressures on vertical wall on its leeside

The hydrodynamic performance of vertical wave screen of different porosity has been studied through an experimental investigation. The variations in the dynamic pressures exerted on a vertical wall as well as its reflection characteristics due to the presence of a wave screen on its seaward side have been studied with an experimental investigation in a wave flume. The studies were conducted for four different porosities of the screen in random wave field. The effects of the screen porosity on the reflection from the wall and the dynamic pressures on the vertical wall have been reported as a function of relative gap ratio between the screen and the wall. The details of model, instrumentation and results are presented and discussed in this paper.
