Abstract

A three-dimensional numerical model for predicting the beach evolution has been developed. A complete numerical model (SLMG2)was designed to represent most of the hydrodynamic factors affecting the problem. The N-Line model was used to simulate the sediment transport al the vicinity of groins system and to predict the shoreline morphological changes around it. The wave computations include wave refraction diffraction and breaking. The validity of the model has been confirmed by  applying it to the calculation of deformation of bottom topography around groins system. The comparison between model results and field data measurements showed a good agreement and indicated the flexibility of the model in handing such cases.
