ResumoThe aim of this study is to characterize the channel pattern of the Paraguay River between Cabacal River and Pelado Hill in the Caceres area (MT). To do so, analyses on the fluvial hydrodynamics, on the morphology of the channel and the floodplain, and on the typology of the fluvial bars, were carried out. The research was developed through the use of the orbital images, hydrologic data and field works. The morphologic analysis, the floodplain landscapes, and the fluvial bars styles showed that such channel presents two segments with different patterns. The upper segment has meandering and braided characteristics and the lower segment has straight and braided channel characteristics and anastomosed forms on their floodplain. The occurrence of different channel pattern characteristics on the studied fluvial segment indicates that the fluvial system is currently in adjustment process, as a result of excessive sandy sediments input.
