چکیده مقاله
One of the most important discharge control ways is side weir Semi circular side weir can be an solution for increasing discharge coefficient In present research the semi circular side weir hasbeen studied to find the influence of hydraulic and geometry variables on the value Furthermoresemi circular side weir has been compared with labyrinth side weir with a beak angle 90° 105 experimental tests were conducted on the semi circular and labyrinth side weir Upstream Froudenumber and discharge coefficient were calculated The results showed that semi circular side weir hashigher coefficient value in comparison with rectangular side weir and labyrinth side weir when beak angle is90° An inverse relationship between Value and was found Also increase in dimensionless height of weir ⁄ was causes the value enhances
