Construction of gabion structures for erosion control and slope stabilization: A case study at Córrego dos Machados in Bom Despacho – MG

Abstract

The increase in the intensity and volume of rainfall, particularly during wet seasons, can trigger erosive processes and sediment accumulation, causing environmental and structural damage to nearby buildings. This study aims to present and analyze the application of gabion structures as a technical solution for erosion control in susceptible areas, seeking to mitigate adverse impacts. The adopted methodology involved a comprehensive literature review on the use of gabions for erosion control, drawing from academic databases, and a case study conducted at the Córrego dos Machados, in Bom Despacho, Minas Gerais, Brazil. In this location, gabion structures were implemented for slope stabilization and protection against erosive processes. The results demonstrated the relevance of gabion structures in erosion control and slope stabilization near watercourses, contributing to the conservation of the riverbed, recovery of degraded areas, and restoration of local biodiversity. Furthermore, the findings presented may support organizational consultancies in technical decision-making related to geotechnical and environmental risk mitigation, as well as assist educators who employ case-based learning methodologies in engineering courses. It is concluded that the use of gabions represents an efficient and environmentally appropriate alternative for the control of erosive processes.
