Agrimensura aplicada na identificação e avaliação de nascentes em bacias hidrográficas

Abstract

The identification and assessment of springs, essential for revitalizing and preserving natural water sources, was the focus of this study in the Santa Bárbara Stream Watershed, located in Monte Carmelo, MG. Surveying can be a valuable technique in promoting the sustainable management of natural resources, as it provides products capable of supporting the management and recovery of degraded areas through effective and sustainable data acquisition approaches. Based on this premise, advanced surveying techniques were employed in this study, including the use of a remotely piloted aircraft (RPA). Through the RPA, spring areas were mapped using Remote Sensing techniques, allowing for a precise assessment of degradation in specific locations. This approach enabled the classification of roads, access paths, and gravel pits, which are fundamental elements in guiding environmental management and recovery strategies. In addition to field data, satellite imagery was used to map property boundaries and land use and land cover outside Permanent Preservation Areas (PPAs). Thus, by employing cutting-edge methods and technologies, the study analyzed and mapped the springs, taking into account topography, vegetation cover, and land use. As a result, a precise mapping of the areas to be protected was achieved, providing a comprehensive understanding of the environment, identifying critical areas for preservation and recovery interventions, and contributing essential information for environmental management.
