Urban Development and Societal Issues

Using the average directions of the main wave-fronts which approach the coast of Bahia State -coinciding with that of the main wind occurring in the area -and of their periods, we define a wave climate model based on the construction of refraction diagrams.The resulting model of sediment transport was able to reproduce, in a general way, the sediment dispersion patterns furnished by geomorphic indicators of the littoral drift.These dispersion patterns control the generation of different types of sediment accumulations and of coastal stretches under erosion.We demonstrate that the presence of the Abrolhos and Corumbaú Point coral reefs is an important factor controlling the sediment dispersion patterns, since them act as a large protection against the waves action.
