Aplicação do diagrama de Pejrup na interpretação da hidrodinâmica do Estuário dos Bons Sinais - Quelimane

Abstract

The present study aimed to interpret the Bons Sinais Estuary hidrodynamics through surface sedi-ments textural analysis, statistical parameters and the aplication of Pejrup Diagram. From this way, we could infer the energetic conditions that acted during the deposition of sedimentes in the Estuary. We collected surficial sediments of the Estuary using a grab corer and the samples were further analysed in the Laboratory of Sedimentology of the Eduardo Mondlane University. The analysis consisted on conventional sieving and pipette methods. The results show that the sediments that cover the bottom sediments are mainly fine and very fine sand, with slight predominance of clay and silt in some parts of the Estuary. The hydrodynamics infered through the Pejrup Diagram is predominantly very high, with a few parts classified as high to moderate.
