Abstract:
Structural water deficit is common to all Mediterranean regions. Demand concentrates in summer under dry-arid conditions, while precipitation mainly occurs in winter. Water availability also exhibits large interannual fluctuations. In the Guadalquivir River Basin in Southern Spain, for example, annual availability ranges from 400 to more than 20000 Mm3/yr, while yearly water demand remains stable at 3500 Mm3/yr. In such a context of extreme hydrological variability, man-made reservoirs used for drinking water supply and/or irrigation, are strategic infrastructures.
