“…e increase in the degree of pollution is linked to the decrease in the flow of the Zegzel watercourse during the dry period and the canalization of water for the irrigation of agricultural plots. Similar works have shown that river pollution is relatively higher during the dry season than during the wet season [66][67][68].…”

“…La quantification des pertes en sol au niveau du bassin versant du barrage Hassan II a été réalisée en adoptant l'équation universelle de perte en sol (RUSLE) établie par Wischmeier (1978) puis modifiée par Renard et al (1996). (Chaoui, 2013) La moyenne annuelle de perte en sol (A) est calculée comme suit : A = R*K*LS*C*P Avec : A= taux annuel moyen de perte en sol en t/ha/an, R = facteur de l'érosivité des pluies en MJ.mm/ha.H.an, K =facteur de l'érodibilité des sols en t.ha.H/ha.MJ.mm, LS =facteur topographique sans dimension combinant la pente (S en %) et la longueur de pente (L en m), C =facteur du couvert végétal sans dimension, P =facteur des pratiques culturales antiérosives sans dimension.…”

“…Ensuring that freshwater quality is appropriate to human and ecological needs is, therefore, an important aspect of integrated environmental management and sustainable development. To provide a clear picture of water quality, various water quality indices are used to assess the quality of surface water (Telhaoui, El Hmaidi, Hajar Jaddi, & Ousmana, 2020).…”
