This study analyzes the hydro-sedimentary impact of storm Juliette in an agroforestry basin in the Balearic Islands. Flow data and sediment samples were used to assess its origin and transport. Juliette brought 208.3 mm of rainfall in five days, with a peak flow of 2.4 m³/s and 3.9 t/km² of sediment, exceeding the 2012-2018 average. The main sediment sources were channel margins and agricultural soils, highlighting the impact of extreme events on the basin's dynamics.
