This paper studies the performance of side weirs by changing the end lip slope of this weir using three angles (0,3,6) opposite flow direction, depending on Froude number and slope of side weir end lip, an equation for the coefficient of discharge for the side weir has been defined. From the results it was found that the side weir inclined (3) decreases the water head above it by (8%), with respect to horizontal lip of side weir, while this value reach to (12%) when side weir lip inclined (6). This mean increasing the discharge pass over side weir by increasing slope of side weir end lip opposite flow direction, then this weir can be used as a good escape the surplus discharge as well as will be more economy when compared with the horizontal lip side weir. (for horizontal channel and subcritical flow).
