, or overflow spillway, is a critical hydraulic structure used primarily with gravity dams to release excess floodwater safely. Its characteristic S-shaped profile is designed to mimic the lower nappe of a freely falling water jet, ensuring the water maintains contact with the structure to prevent cavitation and sub-atmospheric pressure. Modern engineering relies on Excel-based tools (XLS) to automate the complex iterative calculations required for these profiles. 2.
