Description
The Nachtigal Dam, part of the Nachtigal Amont Hydropower Project in Cameroon, features a 4917-meter-long labyrinth spillway, designed to safely manage floodwaters. This spillway was optimized for hydraulic safety, cost efficiency, and environmental considerations. Physical scale modeling (at a relatively rare 1:12.5 scale) and detailed design adjustments ensured robust performance under various flow conditions. Despite construction challenges for such a large-scale nonlinear structure, the project achieved reliable spillway operations, demonstrating the suitability of labyrinth weirs for large-scale hydraulic infrastructure.
