Quick Summary

A ski-jump spillway is a type of engineering structure designed to safely release excess water from a dam when the reservoir is full. Unlike traditional spillways that might flow over the dam or through a channel, a ski-jump spillway deflects the water jet upwards and away from the dam's base. This design is particularly useful for higher dams, as it helps to control and dissipate the water's erosive energy away from the dam's foundation and the riverbed below. This prevents potential damage and catastrophic failure that can occur if a dam is overtopped.12
