Acesso em:.http://bdm.ufpa.br/jspui/handle/prefix/1781Morphosedimentary characteristics and morphological, sedimentary and hydrodynamic patterns of many beaches of Pará North coastal have been studied by many authors. But, studies about short period dynamics of these environments are rare in the scientific literature. Thus, this work aims the verification of active, dominant and/or present systems in Pescadores beach, as well the characterization of the beach in a short period. Field trips were held for fifteen consecutive days where topographic transects were made, along with collect of samples of surface sediments. Topographic transects were made using an automatic level, in two separated locations in an area sheltered from wave action, only with tidal influence, and in a region exposed to wave and tidal actions. Sediment collect was made at low tide line to be the region with the greatest fidelity to the processes occurring on site such as action of flood and ebb currents, winds and tides. Results showed that in general, the exposed transect presented itself an erosive region and the sheltered transect presented itself a depositional region, noting that the major changes were episodic in both profiles, as a result of climate oscillations. Results also demonstrate the relevance of morphosedimentary variations in hours and days scale of on beaches in Northern Brazil, as well as its dependence on the degree of exposure to wind and waves.Acesso AbertoSedimentologiaPraia de macromaréPraia dos PescadoresCNPQ::CIENCIAS EXATAS E DA TERRA::OCEANOGRAFIATrabalho de Curso - Graduação - Monografia
