Abstract
The discharge capacity and hydraulic efficiency of a labyrinth weir can be increased with an Arced cycle configuration. An Arced geometric layout for labyrinth weirs is presented, including nomenclature for arc-specific geometric variables. Discharge coefficients as a function of HT/P for half-round trapezoidal Arced labyrinth weirs with 6 and 12° sidewall angles are also presented. The hydraulic performance of the tested Arced labyrinth weir geometries is compared to Projecting and in-channel labyrinth configurations and to an arced weir (horseshoe weir) with a half-round crest, including the effects of approaching flow conditions and local submergence. Differences between geometrically similar and geometrically comparable Arced labyrinth weirs are identified and discussed.
