PARDO-GOMEZ, Rafael  e  LOBAINA-FERNANDEZ, Susel. The employment of ogees type WES and elliptical in spillways type labyrinth. Part I. Tecnol. cienc. agua [online]. 2019, vol.10, n.3, pp.1-11.  Epub 21-Abr-2021. ISSN 2007-2422.  https://doi.org/10.24850/j-tyca-2019-03-01.

Labyrinth type weirs are relatively new as their started by the middle of the past century. The nineties decade and beginning of the present century have witnessed a great deal of laboratory scale research about this type of weirs. In the present work experimental research results are shown to evaluate the possibilities of employing type WES or elliptic ogees within the labyrinth type weirs given the advantage of a better discharge coefficient as related to other ogee types. Results from two-dimensional laboratory scale models are presented relative to truncating both structures to allow their use in labyrinth spillways.

Palavras-chave : Labyrinth weirs; weir crest types; WES ogees; elliptic ogees; truncated ogees; weir with ventilated sheet; weir with non-ventilated sheet.
