Abstract

Understanding the dynamics of the landscape has always been at the heart of geomorphological analyses. The watershed received great prominence due to their dynamics and their role in the evolution of the relief and its forms, making necessary an increasingly detailed approach to the relationships between the drainage networks and the relief. Thus, this research focused on the analysis of the Mundaú River Basin (BHRM) and four (04) of its sub basins, through the application of morphometric indices such as the Bifurcation Ratio (Rb), analysis of Hipsometric Curves and Integrals (HI) and the Drainage Basin Asymmetry Factor (FABD). Establishing relationships with the rocky substrate and the presence of faults and shear zones, it was found that, for the most part, the sub basins have their relief in a mature state, where there is a large percentage of geological homogeneity, predominantly metamorphic rocks, which do not have great structural influence on the drainage network. In addition, most su bbasins have tilt to the left flank, most likely influenced by the presence of faults and shear zones. Thus, it was possible to verify certain conditions that contribute to the understanding of the current relief stage, of BHRM as a whole, contributing to a better understanding of its dynamics.
