Variability of reference evapotranspiration and water demands. Association to ENSO in the Maipo river basin, Chile

This study shows that there is an ENSO footprint on reference evapotranspiration as well as on total water demands. During austral winter and spring seasons, reference evapotranspiration can show differences up to 30% between La Niña and El Niño years. Total water demands in the basin are increased by 20% during La Niña years.
