Abstract:

 Drought is one of the important phenomena resulting from climate variability and change in recent decades. Its indirect effects over time can have economic, agricultural, hydrological or social impacts. The objective of this study is to characterize the climatic drought at the level of the watershed of Oued El-Abid (central High Atlas, Morocco). For the period 1986/2021 through the calculation of the normalized precipitation index (SPI) at different time scales: 3 months, 6 months, 12 months and 24 months for the five stations studied: Tizi N'Isly, Ait Ouchene, Zaouit Ahansal, Tillouguit and Ouaouirnth. This index studied in the short term (03 months and 06 months) indicates that the study area observed a moderate drought over 9.07% to 12.09% of the total time analyzed. In the medium term (12 months) 10.93% at 12, 56% of the time analyzed recorded moderate drought. Long-term (24 months) SPI values indicate that 8.37% to 13.49% of the total time analyzed recorded moderate drought. ; 2.09% to 7.21% of the total time analyzed is marked by extreme drought. Keywords : Meteorological drought,  Oued El-Abid watershed, standardized precipitation index (SPI).
