Dams are multipurpose structures that provide water for drinking purposes, hydroelectric
power generation, navigation, industrial uses, and irrigation, in addition to flood control. The …

A comprehensive experimental investigation was performed to better understand the effect
of the weir geometry of a Piano Key weir (PKW) on the discharge coefficient for both free and …

Piano Key Weirs (PKWs) are an alternative to linear overflow structures, increasing the unit
discharge for similar heads and spillway widths. Thus, they allow to operate reservoirs with …

Forum papers are thought-provoking opinion pieces or essays founded in fact, sometimes
containing speculation, on a civil engineering topic of general interest and relevance to the …

Labyrinth weirs are complex hydraulic structures. They have been widely used as a water
regulator and to increase discharge in channels and spillway dams. Labyrinth weirs are an …

One of the challenges associated with Piano Key Weirs (PKWs) is the nappe oscillation of
the flow passing over them. Aeration of the flow has been identified as an effective method to …

Hydraulic engineering of dams and their appurtenant structures counts among the essential
tasks to successfully design safe water-retaining reservoirs for hydroelectric power …

Due to their small footprint and efficient hydraulic performance, piano key weirs (PKWs)
have been gaining growing attention in the past two decades. Besides the primary …

Abstract Piano Key Weirs (PKW) have been invented in the last decade to increase
discharge capacity of hydraulic structures. Despite extensive studies on this type of weir with …

Side weirs are widely used to divert a part of the discharge in irrigation channels and sewer
systems. To increase the discharge capacity of linear side weirs at constant length in a …
