Piano Key Weir

The #Piano #Key #Weir, representing a relatively #new variation of the #labyrinth #weir, was developed by Biskra University in #Algeria in #collaboration with Hydrocoop #France. These #weirs #offer the #advantage of being #installable in confined spaces, such as atop #concrete #dams, while still providing the same #efficiency as #traditional #labyrinth #weirs, thanks to the inclusion of overhangs. #Piano #Key #Weirs are typically designed with a #rectangular shape in #plan #view with an inclined #bottom. Due to their intricate geometry, these weirs generate #complex #flow #patterns that are challenging to #predict using #analytical #methods. Consequently, numerous #researchers have turned to #numerical #modeling to #investigate the flow #characteristics over such #weirs. This #video showcases the varying #flow patterns over a #piano #key #weir, illustrating changes from the top to the #bottom of the #channel.
