AB Drought temporal characterization is a fundamental instrument in water resourcemanagement and planning of basins with dry-summer Mediterranean climate and with a significantseasonal and interannual variability of precipitation regime. This is the case for the Lower GuadianaBasin, where the river is the border between Spain and Portugal (Algarve-Baixo Alentejo-AndalucíaEuroregion). For this transboundary basin, a description and evaluation of hydrological droughtevents was made using the Standardized Precipitation Index (SPI) with monthly precipitation timeseries of Spanish and Portuguese climatic stations in the study area. The results showed the occurrenceof global cycles of about 25–30 years with predominance of moderate and severe drought events.It was observed that the current requirements of ecological flows in strategic water bodies werenot satisfied in some months of October to April of years characterized by severe drought eventsoccurring in the period from 1946 to 2015. Therefore, the characterization of the ecological statusof the temporary streams that were predominant in this basin should be a priority in the nexthydrologic plans in order to identify the relationships between actual flow regimes and habitatattributes, thereby improving environmental flows assessments, which will enable integrated waterresource management.
