In the state of Rio de Janeiro, mass movements on slopes have become one of the most important geotechnical problems due to their rugged terrain, occupation and harsh weather conditions. In order to identify an alternative to evaluate slopes using non-invasive methods that enable work in hard to reach places, with rapid and continuous data acquisition, this paper presents a theoretical and practical analysis of this evaluation process using geophysical methods and continuous monitoring ground water through sensors. Geophysical surveys using georadar and multichannel analysis of surface wave to investigate the stratigraphy of the studied slope, allowed the identification of three layers: mature soil, young residual soil and rock. For the continuous monitoring, volumetric humidity and suction sensors and a rain gauge are used for a period of 6 months with data collection every 10 minutes. With the interpretation of the collected data, a good monitoring functionality was verified to evaluate the suction and volumetric humidity responses during periods with irregular rain intervals. The identified precipitation and stratigraphy data are used in the infiltration and saturated stability analyzes, which allowed the identification of critical sections with safety factor below 1.5, where interventions are necessary to ensure the safety of the neighborhood.
