Terras caídas e seus impactos na sedimentação do leito do Paraná do Ramos Parintins - AM

Abstract

The dynamic river of the Amazon river is characterized by the constant transformation of their margins, either by erosion, by sediment transport or sedimentation. The present work aims to investigate the origin of the phenomena of erosion occurring on the slope of the Paraná do Ramos and the effects that they cause in the study area. The study area presents a landscape that is in constant modifications and that for a very long time comes a calling attention by the transformational processes that modify the landscape, geomorphological, mainly by the phenomenon of land sagging and sedimentation of waterway. To validate the research, surveys have been conducted on bibliography on the subject in the region, the analysis of satellite image in time series, measurements of hydrodynamics such as speed, flow, and longitudinal profile of the channel, with use of echo sounder digital, flutuares plastic, vessel, regional, tape measure, stopwatch, camera and GPS, in the field activities. With this, through the results obtained, gave him to understand that the erosive processes occurring within the study area, causing impacts to both the population resident in the area as well as for the transport, showing that the area through these processes, is gaining a facelift in geomorphology.
