Abstract

In terms of the importance of constructing mega coastal structures, in Egypt, hydrodynamic efficient economic measure should be innovated to protect such mega structures. Accordingly, this research was initiated with the objective of investigating an innovative hydrodynamic efficient economic breakwater, theoretically and numerically, where Unsymmetrical Dual Vertical Slotted-Walls "UDVSW" was proposed to be investigated.  Primarily, literature in the field of breakwaters so as numerical models were assembled and scrutinized. A theoretical model was implemented and solved by Eigen-function technique for linear waves. In addition, a numerical model was constructed, where it is based on 3-D simulation code. The model investigated wavelength and wave period impact on UDVSW, in terms of its identities (i.e. solid length of its upper part and porosity of its lower part). Results were obtained; analyzed and presented. In addition, the numerical and theoretical results were compared against previous experimental results, from which clear their compatibility.  The obtained results highlighted that the models are capable of estimating the energy dissipation, transmission and reflection coefficients within an acceptable accuracy, from the Engineering point of view. In addition, the results emphasized the efficient performance of the theoretical and numerical models in estimating UDVSW identities and wave velocity.
