On Simple Ways to Determine the Reverse Curve of Medium-Small Sized Gravity Overlow Dam

讨论堰面曲线、直线段、挑射角都已选定的情况下，在可行性研究阶段和初步设计阶段中小型溢流重力坝反弧段确定的简易方法。

At the stage of the feasibility study and primary design of the gravity overflow dam,the simply ways to determine the reverse curve were discussed after the curved surface,the straight segment and the angly of emergence of weir have been fixed.
