Cuantificación del déficit hidrológico reciente en la región de Cuyo a partir de indicadores de caudales bajos
This study quantifies the deficit in the streamflows of the main rivers in the Cuyo region, associated with the extraordinary hydrological drought recorded since 2010. These deficits show record-breaking values in the context of the last 50 years,particularly during the 2019/20 hydrological year. Re...

| Sumario: | This study quantifies the deficit in the streamflows of the main rivers in the Cuyo region, associated with the extraordinary hydrological drought recorded since 2010. These deficits show record-breaking values in the context of the last 50 years,particularly during the 2019/20 hydrological year. Regional differences in cumulative deficit values allow us to establish that the greatest severity was observed in the Atuel and Colorado river basins, which on average recorded streamflows below the 80%excedance percentile (Q80) during the 2010/11-2019/20 period. By standardising the cumulative deficit by the volume of the region's reservoirs, we obtained a measure that is easy to interpret and to apply for monitoring and decision-making regardingthe impact of hydrological drought on regional freshwater availability. |
