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 …

This paper presents an experimental study of the acoustical effects of cavitation caused by a
water flow through an orifice. A circular-centered single-hole orifice and a multi-hole orifice …

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 …

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 …

3D printing is a fast growing industry and is affecting many areas of our daily lives, eg, in
medical fields, mechanics, as well as engineering. For hydraulic experimental modeling, this …

The effects of geometrical parameters (crest height, number of cycles, and plan weir
configuration), are investigated experimentally on labyrinth weirs, over a range of headwater …

Rectangular piano key weirs (RPKW) have been introduced as an innovative type of
labyrinth weir with a smaller footprint and high hydraulic performance. To date, limited …

A Piano Key weir (PK weir) is a nonlinear, labyrinth-type weir well suited for rehabilitation
projects due to a relatively small footprint and the ability to pass large discharges for lesser …

Large wood increases the morphological and hydraulic complexity of rivers, yet it may block
and modify the flood discharge capacity of hydraulic structures. To assess the related risk …
