I'll cite relevant sources.gee spillways are among the most efficient and widely used hydraulic structures for safely discharging excess water from a dam reservoir. Their characteristic "S" shape is designed to precisely match the underside of a free-falling nappe, creating a high-efficiency overflow system. In the world of modern dam engineering, the efficiency, speed, and accuracy of the design process are critical. While many engineers still rely on manual calculations and generic formulas, the industry is increasingly adopting integrated digital tools, with Excel-based design workbooks ( .xls files) at the forefront of this movement.

The (or overflow spillway) is a specialized hydraulic structure designed with an S-shaped crest that mimics the profile of the lower nappe of a freely falling water jet. This design is considered "better" than standard straight-drop spillways because it ensures the water sheet maintains constant contact with the spillway face, effectively eliminating the risk of sub-atmospheric pressure and damaging cavitation . 1.
