Resumo:Embankment dams are vital structures for society; however, their operation may involve significant risks. Traditional monitoring methods are fundamental for dam safety, yet they may present operational limitations, such as blind spots, obsolete systems, and inoperative equipment. This work proposes a complementary methodology based on drones to support the early detection of anomalies in these structures. It provides technical guidelines for optimised flight planning and photogrammetric processing using open-source software (WebODM). It also introduces the GCP Finder tool for automating the georeferencing of control points. The case study of the Lapa Dam demonstrates the ability to detect anomalies with sub-centimetre resolution, enabling the quantification of deformations of 15–20 mm on the crest. The results confirm the potential of drones as an emerging tool for dam safety, offering comprehensive coverage at low cost.
