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 …

Piano key weirs (PKWs) are an increasingly popular hydraulic structure due to their higher
discharge capacity than linear weirs. Accurately predicting the discharge of PKWs is …

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

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 …

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 …

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 …

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 …

ABSTRACT Piano Key Weir (PKW) is a non-linear weir with a small foundation footprint that
allows large discharges through a narrow channel. The presence of overhangs classifies it …

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