Description
This paper presents ARTELIA’s gradual approach for the design and construction of labyrinth weirs, from the preliminary concept design to the commissioning. It is illustrated with the case of La Laye dam, where an additional lateral spillway with labyrinth weir has been developed to increase the existing discharge capacity. The design process involved preliminary hydraulic calculations, 3D numerical modeling and a physical scale model. The paper elaborates on the technical solutions and optimizations which were considered to provide the Client with the most hydro-economical solution.
