Abstract

Maranhão Harbour Area is the second biggest port complex in cargo handling of Latin America and one of the greatest of the world, with more than 85 million tons loading rate in 2006, which is more than 15% of the annual cargo handling of the country. Considering the great amount of available information of the study region, the main purpose of this work is to describe the tidal currents circulation and corresponding sediment transport in the Maranhão Harbour Area through numerical model applying the software MIKE 21 - HD and ST. The hydrodynamic model results permitted to check the accuracy of the model in reproducing the currents recirculation patterns in the area of PDM. The model of the sand transport reproduced with accuracy the bottom evolution and sedimentation rates. At last, it is important to emphasize this research in the national context, because is unique such continuous detailed Harbour Complex project improvement, contributing to reduce the simple empirical project and operation procedure.
