River water quality fluctuates from source to downstream as a result of anthropogenic water pollution, which can be caused by point source discharges (such as industrial or urban wastewat er) or di ffuse loads (such as agricultural discharges ), combined with the influence of variables like temperature and water flow.
This study investigates the effects o f seasonal and geographic flow variations, anthropogenic pollution, and water quality on the ZAT River in Morocco. The weighted index (WI), is used to establish the chemical assessment of water quality. Moreover, the Iberian Biological Monitoring Working Group's biological index IBMWP is used to evaluate water quality.
