Abstract:

Study of beach profile evolution due to the wave and current impacts in the coastal zone has been one of the most important issues in coastal engineering research projects during the past decades. To construct the coastal protective structures such a piers, breakwaters and seawalls, it is necessary to estimate bed level changes in the vicinity of such structures. Furthermore. the time-dependent changes in the equilibrium profile of the surf zone can be of great importance in designing coastal structures. Because of the importance of coastal engineering study in Iran due to the existance of two important coastal area located in the north and souch parts of the country. and due to the lack of classified data in this respect in the present study. based on the available data of Bandar Anzali region, an analysis of the coastal zone behaveior is made bed level eleevations are measured and compared with the theoretical equilibrium profile. It is shown that the behaviour of the coastal zone in the region is consistent with the Dean (1991) equilibrium profile. The results obtained from the present study indicate thet the surf zone behavior depends on the wave climate and location with respect to the shoreline. The estimated current velocities are graphically presented which can be usedd for design purposes and establishing a data base for the coastal zone in the study area. it is belived that the present work can be regarded as a contribution on the existing knowledge of coastal engineering in the study area and referred to as a basis for the future coastal research projects.
