Land use and land cover change in the Yí River Basin, Uruguay

Summary

This presentation analyses how land‑use and land‑cover changes between 2007 and 2023 have influenced flooding dynamics in the Yí River Basin, Uruguay. Using Sentinel‑2 satellite imagery and a classification of key land‑use categories—such as infrastructure, crops, natural grassland, forestry, native forest, water, and fallow—the study identifies increasing flood frequency in urban areas and demonstrates how shifts in land use alter hydrological behaviour.

The work highlights classification challenges (e.g., distinguishing fallow from natural grassland or forestry from native forest) and emphasises the need for basin‑scale environmental analysis, improved validation methods, and correlation with hydrological data like streamflow, rainfall, and historical flood records.
