%X Since the 1970s, as advanced agricultural frontier in the center of Brazil, there have been significant changes in land use in some regions, because of inappropriate agricultural practices. Due to these changes, the presence of erosive processes that resulted in a great loss of soils, which are transported downstream, thus causing impacts of sedimentation in the fluvial channels. The Araguaia river is one of the rivers that suffer from this process, having na average daily transport of suspended sediments of 2, 622,274 tons, in the years studied from 2002 to 2016. These changes also generated a greater dynamics of sedimentation by the sandbanks now they are depositing, another is eroding. Using high resolution (Google Earth), it was possible to map the dynamics of these sandbars in 6 distinct year and thus identify that they varied from 247.56 km² to 2057.15 km² in the same stretch. Understanding this sedimentar dynamics in water courses is of great importance, since it has determined the feasibilty of installing water projects, such as dams waterways, hydroelectic plants like others. The use of satellite imagens can be seen as a great tool in the management and monitoring of environments which has of great environmental importance for living things.
