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 …

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 …

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 …

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 …

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 …

The assessment of scour depth downstream of weirs holds paramount importance in
ensuring the structural stability of these hydraulic structures. This study presents …

Abstract Piano Key Weirs (PKWs) are often preferred over other spillways for the dam
rehabilitation due to high discharging capacity. The present study investigates scour …
