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 …

A piano key (PK) weir is a type of nonlinear (labyrinth-type) control structure with a relatively
small spillway footprint. No standard PK weir design procedure is available, and the amount …

In this paper, the discharge coefficient of triangular labyrinth weir was predicted using multi-
layer perceptron (MLP) neural network and Adaptive Neuro Fuzzy Inference System …

With inertia and gravity representing the dominant forces for most open channel flow
applications (eg weir flow), Froude similitude is commonly used for scaling hydraulic …

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

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 …

The discharge coefficient (Cd) plays a vital role in the accurate design and safety of weirs,
spillways, and dams. In the last decade, Soft Computing (SC) models, which showed …

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 …

Dams fall in 'installations containing dangerous forces' because of their massive impact on
the environment and civilian life and property as per International humanitarian law. As …
