Water quality monitoring of streams and river has been conducted in many regions across the globe, with the goal of protecting human health and the environment. However, particular concern has been on the concentration of sediments and nutrients in water flowing through rivers, given the potentially detrimental effects these constituents have on river health and receiving systems downstream. Sedimentation and turbidity are equally important contributors to declines in riverine fauna and the overall decrease in environmental aesthetic. In this study, Water quality parameters were examined for the Saijo river during the flood period for physicochemical properties such as pH, alkalinity, conductivity, turbidity, Solids and dissolved oxygen (DO). These results are meant to help water resource managers assess and predict local effects of such contaminants on the environment.
