Flow discharge over side-weirs in rectangular channels derived by the De Marchi equation and discharge coefficient for the flow has been estimated through many experimental investigations. In this study the discharge coefficient for the dischalge over the side-weir along the main channel with side slope of 1 to m is obtained from experimentally and theoretically. An empirical formula of discharge coefficient for the considering flow is proposed as functions of Froude number and side slope of the main channel for the range of F₁=0.3-0.8 and m=0-0.7.
