Abstract

The study of the current velocity in the coast of AMIR ABAD PORT is important in analysis of environment and fishery problems. Current velocity causes of faster transfer to industrial waste to this region and affective the ecological processes on aquatic organisms. This research presents a numerical three dimensional model for the prediction of sea current velocity and wind driven circulation in Amir Abad region of SOUTH CASPIAN SEA. This NUMERICAL MODEL is based on the governing equations of current and by using FINITE DIFFERENCE METHOD supposing Dx and Dy constant and Dz is variable. The study region dimension is 2.2×7 km2 and every mesh size of model is DX=DY=100 m2. In vertical direction in 4 layers with thicknesses varying from the surface to the bottom respectively 5, 15, 25 meters, and more has been considered. The coriolis parameter is constant and hypotheses such as hydrostatic and Bussinesq approximation has been used. In this study, the temperature was considered as a constant parameter. The results of solving the model show that the current speed is approximately 10 cm/s which represents a good evaluation and about 20 percent error, compared with the measurements done by the ports and Navigation Organization at a similar time.
