Abstract Wind waves play an important role in the hydrodynamic processes along the Mediterranean coast of Egypt. Study of waves is essential in the design of navigation channels, coastal protection and onshore/offshore structures. In this study, a third Generation model for prediction of wind generated waves is applied to predict wave characteristics along the Mediterranean coast of Egypt at EI-Dikheila, Abu Quir and Ras Elbar. The model utilizes the numerical solution of the radiative transfer equation of wave energy, incorporating the physical processes of wave generation, propagation and attenuation. The model does not account for wave - current interaction or wave diffraction by natural islands or man made structures. The model can be used for the direct prediction of wave characteristics at intermediate or shallow water depths, as well as for deep water. The wind data of the European Center for Medium Range Weather Forecast are used as the source of the wind data required by the model. This data represent the wind velocities at each node of a geographical longitude and latitude grid. This grid covers all over the east of the Mediterranean sea. The wave data predicted by the model are compared with the actual wave data collected at EI-Dikheila site by the Coastal ReE-earch Institute (CRI). Comparisons show that the predicted and recorded data are in fair agreement. Moreover, Statistical linear relationships are developed between the predicted wave characteristics at both El-Dilibeila, Abu Quir and Ras Elbar. These relationships can be used to fill the gabs in wave recordings at any of the investigated sites. |
