EFFECT OF USING MULTIPLE ROW-PILE BREAKWATERS AS WAVE ENERGY DISSIPATER IN COASTAL AREAS

Abstract

In terms of the importance of safeguarding the coastal zone in Egypt, this thesis was initiated with the motivation of proposing an innovative coastal protection measure and investigating its capability of energy dissipation, experimentally. Primarily, literature was reviewed, analysed, categorized and comprehended. models to solid piles breakwater were designed and constructed. Experimental flume was set up to test these models, where measuring devices were arranged. Contributing parameters (i.e. wave height, period, steepness, piles arrangements, diameters…..etc.) were varied. Measurements were undertaken ;analysed; presented on graphs and discussed. Based on the discussions and within the experimented range of parameters, it was clear that solid piles so as the staggered possess an enormous capability of dissipating the wave energy by a percentage that ranged between 20 to 75%, which is considered to be a reasonable amount from the coastal engineering point of view.
