In order to understand and predict geomorphologic evolutions in coastal seas and estuaries a model is needed which describes the dynamics of the water motion, sediment movement and the evolution of erodible boundaries (like the bottom). The latter two modules require quantitative information about erosion, deposition and transport of sediment. The structures are constructed to the long one of the coast for some purposes and cause modifications in the natural environment with change of the circumstantial shoreline. The conception of the port of Pecém required of the government to study and to hinder the possible alterations of the coast line next to the constructed structures. Then, through numerical simulation, using modern software, MIKE21 and LITPACK, it was studied and one foreseen the behavior of the shoreline in the ten following years to the beginning of the construction, 1996. This work intends to verify the reality of that forecast. The results for the dynamics of the shoreline of the region of the port of Pecém had been gotten through comparisons of its evolution since the initial moment of the construction that terminal port, showing, thus, the transformations caused by the transport of the sediment in two periods of study, before and after the construction of the provisory docking, and to compare with the results determined for the numerical simulations of software, MIKE21 and of LITPACK
