The physico-chemical parameters of surface water from the largest Maghrebian river flowing into the Mediterranean Sea, the Moulouya River, show a large variability in space and time, under the influence of natural and anthropogenic phenomena. This study was conducted between March and August 2014, and involved regular bimonthly monitoring of nine a...

In 2014–2019, we carried out an examination of Trichoptera of the Moulouya River basin in the Oriental, Fèz-Meknès and Drâa-Tafilalet regions of Morocco. Caddisflies of the territories of the High Plateau, the oriental Sahara and the eastern parts of the Rif, Middle Atlas and the High Atlas have been studied for the first time. We collected and ide...

Melloulou River, which is located in Middle Atlas of Morocco, is a good example of a very wet and poorly known basin, and therefore of special conservation concern.

«Performances d’abattement des germes pathogènes en lagunage naturel sous climat aride : cas de la filière de traitement des eaux usées de la ville de Taourirt»

Water resources are limited in Morocco owing to the dominant semi-arid climate and episodic droughts. Furthermore other problems concern qualitative aspects of these resources necessitating a sustainable management. Industrial, agricultural and/or urban activities could affect natural water quality and consequently its use, such us the Meknès Regio...

Les ressources en eau au Maroc sont limitées en raison du climat semi-aride qui caractérise la majeure partie du territoire. A ceci s'ajoute les sécheresses épisodiques. Cette problématique ne se limite pas à la quantité des ressources en eau, mais porte également sur la qualité de ces ressources qu'il faut aujourd'hui plus que jamais bien gérer. L...
