Aspectos estruturais e geomorfológicos da bacia hidrográfica do Rio Bonito, Região de Caiapônia, Goiás, Brasil

Structural and geomorphological aspects of the Bonito River basin, Caiapônia Region, Goiás, Brazil

Abstract

Abstract: The present research was conducted in the Bonito River Hydrographic Basin, located in the state of Goiás, Brazil, in the Cerrado Biome environment. The objective was to carry out an integrated characterization of the structural aspects of Geology, Landforms, and Pedology by preparing thematic maps, graphs, and tables, including a synthesis in all geomorphology units. The data were acquired in secondary vector data surveys processed with the support of QGIS 3.28 software, Firenze. The mapping detected geological, geomorphological, and pedological classes, with a significant presence of sedimentary rocks from Paleozoic formations, obtaining an important highlight, on the southwestern erosive edges of the basin, the Serra do Caiapó in the region under research, in the municipality of Caiapônia. Where it is shaped by landforms characterized by erosive, flattened, and weathered residues of sedimentary rocks, detecting a hypsometric amplitude of an average of 500 meters between the highest point upstream in the Serra do Caiapó to the mouth of the Bonito River. In conclusion, soil surveys demonstrate greater class extensions of Oxisols, favored by the pedogenic evolution of areas with smooth-undulating landforms.
