Application des méthodes paramétriques (drastic et si) pour l’étude de la vulnérabilité à la pollution potentielle par les nitrates de la nappe d’eau superficielle de Timahdite-Almis Guigou (Moyen Atlas, Maroc)

Abstract: La nappe d’eau superficielle appartenant au système hydrogéologique fluvio-lacustre et volcanique d’âge plio-quaternaire est située dans une zone subsidente, à effondrement récent, allongée entre Timahdite et Almis Guigou du Moyen Atlas, Maroc. La région d’étude est occupée essentiellement par des zones agricoles caractérisées par une utilisation importante d’engrais chimiques et de pesticides qui représentent, en plus des rejets domestiques, un risque permanent sur la qualité des eaux souterraines. Nous avons… Show more

“…[21,22]. The amount of sediment load depends on sediment production by slopes and the river's transport capacity [23][24][25]. Interactions between Hydrographic Network Organization and Morphology: In the Kert watershed, the interaction between landscape morphology and hydrographic network organization is key to understanding the hydrological dynamics of the region.…”

“…The extent of impermeable surfaces in a certain area is essential in identifying potential groundwater regions (GWPZ) [19]. According to several studies [11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26]28], impermeable surfaces increase surface ow and runoff volume, reduce groundwater availability, and impede water in ltration and percolation. In other words, areas with higher levels of impermeable surfaces have lower potential for groundwater.…”
