For this study, a wave climate model based on the construction of wave refraction diagrams relative to the current boundary conditions was defined and assumed to be valid for the five coastlines. Numerical modeling from the refraction diagrams was carried out considering the angle of incidence and wave height along the coastline. This work has allowed us to reproduce past and current patterns of net longshore sediment drift defined by a conceptual model developed from the integration of sediment cores, aerial photograph interpretation, C14 datings and geomorphic indicators of longshore drift. These results show that, on average, current wave conditions in the east-northeastern Brazilian region seem to have remained characteristically the same from approximately 5100 years BP until the present time. This type of information can be important when attempting to simulate possible future situations in terms of the long-term general behavior of the east-northeastern Brazilian coastal region.Submitted by Ana Valéria de Jesus Moura (anavaleria_131@hotmail.com) on 2012-02-03T18:13:34Z No. of bitstreams: 1 A diachronic view of the net longshore sediment drift during.pdf: 1986401 bytes, checksum: c3c0f55411f0755480dedb5c3449c263 (MD5)Made available in DSpace on 2012-02-03T18:13:34Z (GMT).
