The study of climate impacts takes on an importance in scientific research, particularly on water resources. The present study highlights the situation of the capacity of Foum El Gherza dam in relation to the observed climate changes. Located in an arid zone of south-eastern Algeria, this dam is a typical example of a region fragile to climate variability. The methodology adopted in this work is based on the analysis of the evolution of the climatic parameters (precipitation and evaporation) as well as the hydrological parameters (flow yields, and leaks) in relation to the losses of stored water volume of the studied dam. The monthly values of climatic and hydrological data contain a 60-year time series (1950 to 2010). The results obtained show that the losses in capacity coincide with the negative trend of precipitation. Thus, a significant upward trend in evaporation is responsible for the decline in the volumes of water stored within the dam. The correlation analysis expresses that the losses in capacity of the Foum El Gherza dam have a strong impact with leakage and with liquid inflows.
