Abstract:

Side weirs are flow diversion devices that are widely used in irrigation and drainage networks and urban sewage systems. They are usually built with a squared-edge entrance. The present study focuses on the effect of rounded-edge entrance shape on the discharge coefficient of a side weir under subcritical flow condition in rectangular channels. In this study, 90 laboratory tests were conducted and the results were analyzed to find the influence of non-dimensional hydraulic parameters on the discharge coefficient. From the results, it was found that under subcritical flow condition the side weir with rounded-edge entrance discharges 10% more flow rate than the squared edge entrance. As a result, for equal flow rate, the rounded-edge entrance side weir with small dimensions can be designed for use in practical applications.
