The piano key (PK) weir has advanced over the labyrinth weir to increase the discharge
capacity. Piano key weirs exhibit nonlinear flow behavior and are easy to place on the …

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

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 …

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 …

Abstract The Piano Key (PK) weir is a new type of long crested weirs. This study was
involved the addition of a gate to PK weir inlet keys. It was conducted by the Department of …

Weirs are important hydraulic structures widely used to control the flow rates in open
channels and rivers. As a remarkable parameter, the discharge coefficient (Cd) determines …

Currently, many existing spillways located throughout the globe require rehabilitation due to
dam safety issues. Consequently, there is an increasing need for design tools that facilitate …

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 …

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 …

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 …
