Abstract

Confluence zones are marked by the strong interaction of matter and energy of channels with distinct characteristics and are presented as a unique environment in the context of the drainage basin. In the case of the Pantanal wetlands, the incidence of seasonal flood pulses contributes to the hydrodynamics of the streams and until now there is no studies with that spectrum in the area. In that sense, two campaigns were carried out to the study area, one in the drier season (November 2015) and another one in the wetter season (April 2016), with the purpose to characterize the hydrodynamics of the confluence zone using the Acoustic Doppler for Current Profiler sounder. The primary data were used in the equations to characterize the hydraulic and channel geometry conditions. It was observed the Cuiabá river, although being a tributary channel of Paraguay, has greater dominance in the flow during the drier season, as well as greater flow and velocity. The dynamics between the flows of the two channels has contributed to the perennial flood in the northern portion of the Pantanal.
