Résumé

Climate variability has been identified as one of the major factors affecting water resources. The
purpose of this study is to characterize climate variability in the region of Souk Ahras and to
evaluate its impact on surface and groundwater resources. Various statistical methods, including
Mann–Kendall test, Pettitt test, drought indices, and Fourier filter were used. Pettitt test revealed
the occurrence of breaks over the period (1994–1996), showing significant increase in the annual
rainfall and temperature data time series. The analysis of drought indices provided insights into
the relationship between meteorological and hydrological droughts in the study area. This mainly
revealed that rainfall deficit results in an immediate response to runoff regime and a delayed
response to groundwater level. Moreover, it was found that both meteorological and hydrological drought conditions significantly decreased after the climatic shift in terms of frequency, intensity and duration. Such information is of great importance for managing water resources and
preparing drought mitigation measures.
