Reconocimiento e interpretación de la dinámica de movimientos de ladera utilizando fotogrametría UAV y datos de precipitación

Abstract

Abstract:The main objective of this degree project is to study the dynamics of slope movements using UAV photogrammetry techniques and precipitation data. Based on information on slope movements, unmanned aerial vehicles, and a rainfall station, the methods applied are detailed in the materials and methods chapter, also showing the procedures for data collection and information processing. Using the information obtained from UAVs, orthophotos were compared on two different monitoring dates, generating a digital surface model (DSM) for each of them. From this, the dynamics of slope movements were interpreted using the DSMs created. Furthermore, it is confirmed that precipitation within the area causes landslides and represents a significant impact, as it can infiltrate the soil, reducing its slip resistance. Additionally, the use of DSMs made it possible to determine elevation changes in the terrain, detecting subtle changes at the head, middle, and foot of the slope, the latter being where the greatest surface changes occurred.
