| Abstract | ||
| This study presents a series of experimental investigations on to calculate discharge coefficient of flow over rectangular weir with quarter circular edge crested extending across the full width of the channel(suppressed) to evaluation the discharge coefficient of the flow. Three weirs were constructed and tested for differentdischarges. They were stable over flow pattern, easy to pass floating debris, has fair coefficient of discharge. Data obtained from laboratory experiments provide information on head - discharge relationship for three models with different height and curvature of weir. Each model has an empirical head – discharge equation. The predicted values of discharge coefficient for the proposed models were based on measured discharge and the derived discharge equation. Analysis of the results revealed thatdischarge coefficient is proportional withheight and radius of curvatureand with the upstream head above weir crest. | ||
