Última Patterns of sediment dispersion coastwise the State of Bahia - Brazil Anais da ABC (AABC) BITTENCOURT,ABÍLIO CARLOS DA SILVA PINTO; DOMINGUEZ,JOSÉ MARIA LANDIM; MARTIN,LOUIS; SILVA,IRACEMA REIMÃO. 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...

Ano: 2000 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S0001-37652000000200012 The Barreiras Group in the Northeastern coast of the State of Bahia, Brazil: depositional mechanisms and processes Anais da ABC (AABC) VILAS BÔAS,GERALDO S.; SAMPAIO,FLÁVIO J.; PEREIRA,ANTONIO M. S.. The Barreiras Group is a Miocene to Lower Pleistocene continental terrigenous sedimentary deposit exhibiting a large occurrence along the Brazilian coast. In the Conde region, located in the northeastern part of the State of Bahia, the sedimentological characteristics of these sediments are indicative of a deposition as gravelly and sandy bed load in braided fluvial systems, related to alluvial fans, under an arid to semi-arid climate. The basal portion of the group is dominated by a gravelly-sandy lithofacies deposited by debris flows and pseudoplastic debris flows, with lesser occurrences of subaqueous deposits, characterizing a proximal fluvial system deposition. The upper portion is made up of gravelly-sandy sediments that include subaqueous, debris... Tipo: Info:eu-repo/semantics/article Palavras-chave: Barreiras Group; Tertiary; Cenozoic; State of Bahia.
