Identification of water erosion processes through analysis of land use and land cover changes in a mountain watershed
Land use and land cover change (LULC) has a significant impact on ecosystems by modifying the natural cover, which has consequences on soil characteristics, hydrological and geomorphological processes. Therefore, the objective is to determine the LULC change of the El Negro River basin for the years...

Therefore, the objective is to determine the LULC change of the El Negro River basin for the years 1985 and 2023 through classification supervised with the use of satellite images, analysing the changes and identifying sectors that show evidence of water erosion processes. Thus, the greatest change in LULC is in the vegetation class, which reduced its area from 55 km2 (1985) to 13 km2 (2023), while the agricultural cover increased from 65 km2 (1985) to almost 100 km2 (2023), representing almost 50% of the total area. In addition to this change, it has been possible to identify sectors where different processes of water erosion are developing within the agricultural production fields (mainly in the Piedmont areas) and in the development of the drainage network. Los cambios de uso y cobertura del suelo (LULC) afecta en gran medida a los ecosistemas implicando una modificación de la cobertura natural y provocando consecuencias sobre las características de un suelo, los procesos hídricos y geomorfológicos. Debido a esto, el objetivo consiste en determinar el cambio LULC de la cuenca del arroyo El Negro para los años 1985 y 2023 a partir la clasificación supervisada por medio de imágenes satelitales, analizar los cambios e identificar sectores que evidencian procesos de erosión hídrica. De esta forma, el mayor cambio LULC lo presenta la clase vegetación que se redujo su superficie de 55 km2 (1985) a 13 km2 (2023) y mientras que la cobertura agrícola se incrementó, pasando de 65 Km2 (1985) a casi los 100 km2 (2023) representando casi el 50% de la superficie total. Sumado a este cambio, se pudo identificar sectores donde se desarrollan diferentes procesos de erosión hídrica dentro de campos de producción agrícola (principalmente en zonas de piedemonte) y propias de la evolución de la red de drenaje.
