%X This study examined the environmental changes between two time periods that have occurred on the section corresponding de Jaguari town (RS) on the Jaguari River. For this analysis used Multispectral images from Landsat-5 satellite to verify the changes in landscape, between the years 1983 and 2010. For this work the use of ArcGIS® geoprocessing tools and Envi® to do analyses of area of interest. How to limit the area of study applied a buffer of 500 meters on the banks of the River. After completed all analyses, we obtained numerical data, which served to compare areas counterparts. We obtained a 43.55% increase in the flooded area and an area of 16.71% decrease of vegetation. Increase Riverbed is directly linked to two factors, deforestation and the actual increase of extreme events (the silting of the river result of floods which besides the river overflows in the rainy season, contributed to the collapse of the margins). One can also relate the collapse of the slopes of the river with livestock farming in the region by the action of the animals that leave the soil with less protection.
