Abstract:
The Paraguay River Basin has been intensively occupied since the 1970 years and its channel dynamic has been changing. The dynamics of the fluvial corridor’s margins was studied, tends as objective evaluating the erosion for a period of nineteen years, using the crossing of images of satellite TM Landsat 5 of the year of 1984 and ETM Landsat 7 de 2003, because the method of pins generally used for monitoring riverbank erosion is not good for the Paraguay river because of their dynamics and composition of the banks. Considering the bank erosion, the channel showed a relatively high mobility in both segments (2, 3 m/y). The monitoring of riverbank erosion is extremely important when it have urban areas located near rivers. Cáceres city is located on the left bank of the river Paraguay and has suffered the impacts (social and economic) caused by riverbank erosion. Besides, the monitoring of riverbank erosion allow observe the dynamics of the channel caused by riverbank erosion.
