Abstract
Dissolved oxygen content (DO) is one of the most important water quality parameter in rivers and streams. Hydraulic structures may cause significant impacts on the river water dissolved oxygen concentrations. The oxygen transfer across the air-water interface at a hydraulic structure such as a weir or spillway occurs by self-aeration along the chute and by flow aeration in the hydraulic jump at the downstream end of the structure. In this study; stepped spillway was created small size in a channel. Dissolved oxygen concentrations were measured on this model with various flow rates of water by passing weir. In the light of measured values along the canal, a mathematical model has been developed to how to show a change of oxygen concentration.
