A aplicação de parâmetros morfométricos no estudo do relevo das bacias do Rio Santo Antônio e Ribeirão Grande, Serra da Canastra, Sudoeste de Minas Gerais

2020 
This work aimed to study the morphodynamics of areas that encompass the Rio Santo Antonio and Ribeirao Grande basins, located in the southwestern region of Minas Gerais, by using geomorphometric analysis aided by geotechnology. For such, it was generated a hydrologically-correct digital surface model through a cartographic base in an 1: 50,000 scale provided by IBGE, from which the attributes correlated in the morphometric parameters were extracted and measured, seeking to clarify the linear, areas and hypsometric aspects of these basins. Moreover, front to the complex geotectonic context derived from the diachronic evolution of the southern Brasilia Belt, it was also produced in detail a lineaments map, identifying linear morphostructural and morphological features. Thus, the results sought to spatialize and to illustrate the relationship between the morphometry and the morphology of the study area, confirming the strong influence of geotectonic aspects on these locations, and that despite of the several apparent similarities they have different dynamic energy.
