Abstract

The morphometric analysis is fundamental for understanding the environmental dynamics of any area, aiming the understanding the relief and the local and regional fluvial dynamics. It is possible to quantitatively evaluate the behavior of river basins. The Peixe River watershed, located in the southeastern of the state of Minas Gerais, has distinct morphometric data when compared to the surrounding areas. In order to investigate the morphometric characteristics of the Peixe River watershed, this study aims to correlate morphometric data obtained from longitudinal profiles and Stream-Gradient Index (SL index) to identify anomalous areas of the sub-basins of the Peixe River watershed. Twenty river channels of 5, 6, 7 and 8 order were selected. A total of 126 anomalies were found in these channels, indicating that they have a geomorphological unusual. This configuration assists in the explanation of the altimetric differences and leads to consider differential denudation and neotectonic action as essential elements in understanding the relief of this basin.
