Free surface flow of water in the ‘Werdinsel’ spillway, Zurich..

Labyrinth spillways are very efficient in channeling water flood flows to protect urban areas. From the design viewpoint, the discharge efficiency of the spillways depends significantly on their configuration. Advanced CFD modeling with TransAT is now an affordable optimization tool of spillways characteristics since it allows investigating the impact of different flow conditions and various configurations at low cost and in short delays (of the order of 1 day), compared to lab-scale measurements.
