Analysis between mass balance and meltwater in the Alayripampa Basin in the Vilcanota Mountain Range, Cusco, Peru.
Nilton Montoya1, Miguel Vargas2
High-altitude tropical glaciers play an important role in sustaining the flow of rivers in the context of increase population for agriculture, domestic and hydropower production, In Cusco, Peru, particularly during the dry season and most importantly in drought years. Is also important for unique and delicate ecosystems, pastoral farmland for local populations. However, tropical glaciers have experienced substantial mass loss in recent decades. The lower reaches of the Suyuparina Glacier, were surveyed using a DJI Phantom during the dry season in 2021, 2022, 2023, 2024 and 2025 for to extract DEM and orthoimage and then generate a dense point cloud and resulting orthoimage, and then with that data we were able to analyze the mass balance for those years. And then we compared it with hydrological information on runoff water at two points downstream of the basin.
