During dry periods, surface water resources and, therefore, the stored volumes suffered a sharp decline .It is sometimes difficult to satisfy the demand for drinking water, and also that agriculture. To better manage such a situation, knowledge of climatic factors, and the study of his impact about water resources is essential. This study aims at show the impact of climate variability on the Oued water resources Medjerda (North East Algeria).
