Longitudinal Suspended Sediments Transport in the Jaguaribe River Estuary, Brazil

This is the authors' abstract. We don't add key points for this paper.

The Jaguaribe River estuary lies in a region characterized by climatic irregularities, inserted in semi-arid terrains. storms associated with climatic and anthropogenic processes entailed by a barrage construction, shrimp farms, mangrove and the use and occupation of margins, caused signifi cant changes in the processes of erosion, transport and . These facts gave rise to economic losses and environmental impacts through the siltation of tidal channels and the condition for navigability. Thus, it is important to know the mechanism of sediment production in order to contribute to the management of the activities to be developed. The study aimed to analyze the longitudinal transport of sediment in river estuary based on data collection in situ through parameters of the hydrodynamic, morphodynamic and sedimentological . Samples were collected in two tidal cycles (high /low tide). The analysis of longitudinal profi le revealed retention of in the estuary during the rainy season. The fi ne material comes from the suspended loads from the inside of the basin the contribution of the sandy-mud sediments of the Barrier Formation which borders the west bank of the estuary
