Abstract:
In Algeria, the climate change in recent decades has a negative impact on water resources. The goal of this study is to determine the influence of these hazards on surface water resources in the basin of Macta (North‐ West of Algeria). The study of climatic pulsations is implemented from the climate coefficient (CHM) changes and its moving averages over 3 years. Variations of this coefficient based on years show, for the period 1949‐ 1973, an alternation of wet and dry years. Starting from 1973, a very dry period of more than 20 years was installed in the basin with deficits ranging from 22 to 72%.
