Abstract: Revision erosion (sliding and landslids) on the banks of the transition zone of the Amazon River in the front of the city of Parintins, is a phenomenon regionally known as 'falen lands'. Resulting from the systematic interaction of the complexity of nature's elements and accelerated along with human actives. This natural phenomenon is urban area imposes constant reworking of the banks due to the large volume of tranported water, associated with factors surch as: proximit and depth of the thalwag, water flow and velocity, weak containment structure on the bank, higth atmospheric precipitation, infiltration of sewage on the slope, larges floods. In this sense, using the methodology of bibliographic survey, observation 'in locus' measurement and comparison of data, use of echo souder and remote sesing data, contribuited to the discussion and understanding of the local fluvial dynamics. It is expected, therefore to contribute to the understanding of the phenomenon and possible mitigations of the problem.
