RELATIONSHIP OF DRAINAGE REARANGEMENTS IN THE PROCESS OF GEOMORPHOLOGICAL EVOLUTION OF THE BOA VISTA DEPRESSION, IN THE NORTH OF RORAIMA
Landscape; geomorphological surface; geoprocessing
The process of drainage rearrangement is when a river diverts the watercourse of another drainage network, however, this process is extremely slow and in many cases it is not possible to identify it. Drainage rearrangement is capable of transforming the surrounding landscape. In this sense, it is essential to study it to understand the evolution of the landscape. With the use and improvement of geoprocessing, the study of drainage rearrangements became viable, as there were no means to assist researchers in this area. Given this scenario, the first discoveries of drainage rearrangements are beginning to emerge in Roraima, in northern Brazil. In this sense, the question arises of the existence of the relationship between drainage rearrangements and the formation and evolution of the Boa Vista depression. Therefore, the research aims to understand the relationship between drainage rearrangement and the geomorphological evolution of the Boa Vista depression. To this end, geoprocessing techniques will be applied to identify geomorphological features that will assist in understanding the geomorphological evolution of the Boa Vista depression.
