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

An accurate assessment of energy loss across dams and weir systems is a critical technical
and monetary remedy for understanding the hydraulic system's downstream morphology …

Piano key weirs (PKWs) are acquired and developed for free surface control structures
which improve their performance by increasing the storage capacity and flood evacuation. In …

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 …

Piano Key (PK) and trapezoidal labyrinth (TL) weirs are nonlinear control structures suitable
for narrow channels with high discharge by expanding the crest length of the overflow. In …

ABSTRACT Piano Key Weirs are an effective solution for dam rehabilitation as well as new
dam projects with a high level of hydraulic constraints. In order to improve the efficiency of …

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

Spillways, a major structure in dams for floodwater safety, have a huge impact on social life.
The evolution of spillways has resulted in the Piano Key Weir (PKW) with high discharge …

Abstract Piano Key Weir (PKW) is an evolution with an efficient implementation over
conventional labyrinth weir, especially at low heads. It is used as the crest of spillways and …

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 …
