Human impact changes hydrological connectivity in a Patagonian fluvial basin

We analyzed the interannual fluctuation in the surface area of Cronómetro Lake, and the deterioration of vegetation status in the alluvial fan located before the lake (January 2000 to January 2021). We also studied the periods of humidity and drought and the anthropic work carried out in the basin of the lake to understand their impact on the extension of the lake area and the vegetation status.

Data.csv
Column "Area": Surface Area of the Cronómetro Lake in km2
Column "NDVI": Average NDVI values corresponding to the alluvial fan located before the lake
Column "PPT": Annual accumulated precipitation in mm
SPEI.xlsx : has the data corresponding to the Standardized Precipitation and Evaporation Index (SPEI; Vicente-Serrano and Beguería 2016). We downloaded the SPEI at a time scale of 6 months for the station located at 43.25° S and 71.25° W, with a spatial resolution of 0.5° from SPEI Global Drought Monitor global model (https://sac.csic.es/s pei/home.html; Vicente-Serrano and Beguería, 2016).
