Qualitee Des Eaux - Macrofaune Benthique - Derniere CampagneWater Quality - Benthic Macrofauna - Latest Survey
This dataset from the Geneva territorial information system (SITG) presents results of the latest benthic macrofauna survey, assessed using the IBCH method (2019 version). Macrozoobenthos refers to small aquatic organisms living on riverbeds, including insect larvae, molluscs, crustaceans, and worms. Because their presence and diversity reflect the physico-chemical quality of water, hydrology, and river morphology, they serve as a biological indicator for evaluating the ecological quality of watercourses in the canton of Geneva, Switzerland.Le macrozoobenthos - méthode IBCH _2019 Le macrozoobenthos regroupe l'ensemble des petits animaux aquatiques qui vivent sur le fond de la rivière : larves d'insectes, mollusques, crustacés, vers, …Ils intègrent à la fois la qualité physico-chimique de l'eau, l'hydrologie et également la morphologie…
