Análisis temporal de mediciones GNSS para el monitoreo de movimientos de ladera. Caso de estudio: Yanacocha.

Abstract

Abstract: This study aims to analyze the geomorphological changes related to the movement of a hillslope located in the Yanacocha sector, on the Loja-Zamora highway. To this end, a methodology was used that included the establishment of a network of control points strategically distributed throughout the study area. These points were monitored using the Global Navigation Satellite System (GNSS) and photogrammetry obtained from Unmanned Aerial Vehicles (UAVs), which allowed the determination of displacement vectors and associated velocities. The collection of photogrammetric and coordinate data was carried out in two stages, separated by a period of 176 days. With this information, Digital Surface Models were generated, which allowed the identification of the affected areas and the analysis of the slope's behavior during the study period. The results obtained demonstrate that this methodology is suitable for assessing and monitoring slope movements, contributing to planning and risk prevention in geologically unstable areas.
