Abstract

As part of a project to investigate the hydrodynamic, sediment transport and mixing processes about the large confluences of the Amazon River, a field study was conducted about the confluence of the Negro and Solimões Rivers. This confluence ranks among the largest confluences on Earth the outcomes of this study may also provide some general insights into large confluence dynamics. A detailed series of ADCP, water quality and seismic profile measurements were collected to investigate key hydrodynamic and morphodynamic features about this confluence. Presented here are the key hydrodynamic features observed about this large confluence and how these relate to findings in previous studies conducted in flumes and small confluences. Finally some insights into how the differences in water characteristics and the hydrodynamics of these two rivers may influence the rate of mixing downstream are presented.
