Resumo: The Serra do Espinhaço Meridional is essentially composed of lithologies of the Espinhaço Supergroup, formed mainly by quartzitic, phylitic, conglomeratic rocks, with absolute predominance of quartzites, composing a densely fractured and sheared rigid cover. Serra do Espinhaço is compartmentalized into two geomorphological units: the plateaus, which are very well individualized, and the depression, which is distinguished by a depressed area in a NW-SE direction. Located on its eastern edge, is the hydrographic basin of the Jequitinhonha river, east river, of extreme relevance for the Northeast region of the state of Minas Gerais. Studies approaching fluvial geomorphology are important and relevant to understand how fluvial dynamics influence the hydrological behavior of the river. In this work, the physiographic factors of the fluvial segment of the Jequitinhonha river covering the municipality of Diamantina were analyzed. The physiographic characteristics along this segment directly contribute to its fluvial behavior. Characteristics such as geomorphological features, geological and lithological aspects, climatic characteristics, plant phytophysiognomy, in addition to mining activities, become responsible for changes in fluvial dynamics.

La Serra do Espinhaço está compartimentada en dos unidades geomorfológicas: las mesetas, que están muy bien individualizadas, y la depresión, que se distingue por un área deprimida en dirección NW-SE. Ubicada en su margen este, se encuentra la cuenca hidrográfica del Río Jequitinhonha, río del este, de extrema relevancia para la región Nordeste del estado de Minas Gerais. Los estudios que abordan la geomorfología fluvial son importantes y relevantes para comprender cómo la dinámica fluvial influye en el comportamiento hidrológico del río. En este trabajo se analizaron los factores fisiográficos del segmento fluvial del Río Jequitinhonha que cubre el municipio de Diamantina. Las características fisiográficas a lo largo de este segmento contribuyen directamente a su comportamiento fluvial. Características tales como rasgos geomorfológicos, aspectos geológicos y litológicos, características climáticas, fitofisonomía vegetal, además de las actividades mineras, se vuelven responsables de los cambios en la dinámica fluvial.A Serra do Espinhaço Meridional é composta essencialmente por litologias do Supergrupo Espinhaço, formado principalmente por rochas quartzíticas, filíticas, conglomeráticas, com predominância absoluta dos quartzitos, compondo uma cobertura rígida densamente fraturada e cisalhada.

Estudos abordando a geomorfologia fluvial, são importantes e relevantes para entender como a dinâmica fluvial influência no comportamento hidrológico do rio. Neste trabalho, analisou-se os fatores fisiográficos do segmento fluvial do Rio Jequitinhonha abrangendo o município de Diamantina. As características fisiográficas ao longo deste segmento contribuem diretamente no seu comportamento fluvial. Características tais, como as feições geomorfológicas, aspectos geológicos e litológicos, característica climática, fitofisionomia vegetal, além, das atividades de mineração, tornam-se responsáveis por modificações na dinâmica fluvial.Editora Unimontes2023-09-10info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionArtigoapplication/pdfhttps://www.periodicos.unimontes.br/index.php/cerrados/article/view/648510.46551/rc24482692202322Revista Cerrados; v. 21 n. 02 (2023): Revista Cerrados; 134-1572448-26921678-8346reponame:Revista Cerrados (Montes Claros.
