The Effect of Semi-circular Side Weirs on Hydraulic Properties and Discharge Coefficient of Side Weirs
Journal Title: Journal of River Engineering - Year 2014, Vol 2, Issue 5
Abstract
Side weir is one of the most common hydraulic structures, which is used as a deviatory structure in rivers, irrigation and drainage channels and also in urban sewage collection systems.Semi-circular side weir can be an solution for increasing discharge coefficient. In present research the semi-circular side weir has been studied to find the influence of hydraulic and geometry variables on the value. Furthermore semi-circular side weir has been compared with labyrinth side weir with a beak angle °.105 experimental tests were conducted on the semi-circular and labyrinth side weir. Upstream Froude number and discharge coefficient were calculated. The results showed that semi-circular side weir has higher coefficient value in comparison with rectangular side weir and labyrinth side weir when beak angle is°. An inverse relationship between Value and was found. Also increase in dimensionless height of weir ( ⁄ ) was causes the value enhances. A new equation was developed to calculate .
