This research aims to understand the dynamics of erosive processes and its environmental consequences on the river side of the Amazon River, based on the study of the riverbank of Santa Clara district, in the city of Parintins, seat of the homonymous municipality, in the state of Amazonas. In order to reach this objective, direct observations of the phenomenon on the city border were made, trying to comprehend the process that causes lateral erosion. This is only possible with a vast knowledge from the study of literature on the subject. The use of photographic images, measurements and bathymetry on the river bottom helped in this understanding. The results indicate that, in the river slope of the Santa Clara district imminence, the factors that cause the phenomenon of fallen lands are equivalent to those indicated in the literature on the subject, such as hydraulic pressure, base disaggregation and elements of the climate (rain, wind and temperature). The environmental impacts resulting from this are characterized by the collapse of the access road to the place, of trees and even walls, as well as the change in the natural landscape. It is concluded that the natural elements that act in the production of the phenomenon represent the main factors that lead to the collapse in the place of study, associated with the anthropic action and the lack of public investment to minimize the damages caused to the urbanized area and to the people who live or work there. Keywords: Erosion; Amazonia; Riverpeople; Fallen lands.
