摘要：The Grou River, located in the central Moroccan plateau, seems particularly threatened dueto the lack of proper management. It is in this framework that this study was carried out inthe region of Rabat, Morocco. It is purposed to examine the structure and taxonomicdiversity of benthic macroinvertebrates, and to assess the biological quality of the waters inthis river in order to solve the threat mentioned above. The fauna studied was collectedmonthly between December 2014 and November 2015. In the study, 9409 individualsidentified belong to 33 Families and 40 taxa corresponding to 4 faunal phyla (Annelidae,Platyhelminthes, Mollusks and Arthropods). The values of the Global StandardizedBiological Index (IBGN) classified the waters of the Grou River at the level of station S1 inthe middle category, at the station S2 in the mediocre category and at both stations S3 andS4 in the good category. The results obtained in this study reveal an alarming situationregarding the quality of waters in the Grou River, especially at the S2 station locatedimmediately followingthe confluence zone with the wastewater of the rural commune ofJmaaMoulblad. In order to solve this problem, we recommend a plan for the sustainablemanagement of the Grou River watershed and the construction of a wastewater treatmentplant in the rural community of JmaaMoulblad.
