Cette \u00e9tude pr\u00e9sente l\u2019int\u00e9r\u00eat de certaines m\u00e9thodes statistiques, pour interpr\u00e9ter la variabilit\u00e9 spatiotemporelle des pr\u00e9cipitations des seize stations pluviom\u00e9triques situ\u00e9es dans le bassin versant de Medjerda (Nord- Est Alg\u00e9rien) sur des p\u00e9riodes allant de 19 \u00e0 38 ans. Les s\u00e9ries analys\u00e9es pr\u00e9sentent toutes des ruptures dont la majorit\u00e9 se trouve dans les d\u00e9cennies 80 et 90. La cartographie des indices pluviom\u00e9triques interannuels calcul\u00e9s par d\u00e9cennie sur la p\u00e9riode 1971-2007 montre que les d\u00e9cennies 80 et 90 apparaissent comme d\u00e9ficitaires sur tout le territoire du bassin. Ainsi, une tendance \u00e0 un retour des pr\u00e9cipitations est remarqu\u00e9e pour la p\u00e9riode (2001-2007). \u00c0 l’\u00e9chelle mensuelle, les pr\u00e9cipitations ont augment\u00e9 significativement apr\u00e8s les ann\u00e9es de rupture pour les mois d’hivers et du printemps, \u00e0 l’exception du mois de mars. On observe aussi, une concentration exceptionnelle de pluie dans le mois d’Ao\u00fbt. \u00c0 l’\u00e9chelle journali\u00e8re, l’analyse des fractions pluviom\u00e9triques journali\u00e8res met en \u00e9vidence une tendance \u00e0 l’augmentation des pluies fortes sup\u00e9rieures \u00e0 20 mm apr\u00e8s les ann\u00e9es de ruptures. Le bassin de la Medjerda connait aussi une r\u00e9duction de la pluviom\u00e9trie et une augmentation de la temp\u00e9rature sur une p\u00e9riode allant de (1913-1938) \u00e0 (1969-2007).<\/p>\n
