Evolution of local scour downstream of Type A PK weir in non-cohesive sediments

Journal of Hydrology and Hydromechanics, 2022
A large-scale piano key weir laboratory study was conducted to investigate the evolution of the scour process occurring in the downstream basin for two non-cohesive granular bed materials, including the analysis of scour-hole geometry and patterns at ...

Comparison of energy dissipation in downstream of stepped and baffled spillways of piano key weirs / Comparación de la disipación de energía en aguas abajo de aliviaderos escalonados y desconcertados de vertederos de tecla de piano

Tecnología y ciencias del agua, 2020
Heavy seasonal rains over a dam reservoir can lead to huge floods and consequent failure of the dam structure. One way of controlling the adverse effects of heavy rains is to use weirs with larger dimensions such as piano key weirs (PKWs).

Experimental Study of Flow Hydraulic in Piano Key Weirs at Different Parapet Wall [PDF]

علوم و مهندسی آبیاری, 2016
Piano key weirs are a new type of Weirs that are designed to improve dams discharge capacity. Generally in increasing the upstream head water decreases the discharge capacity this tyre of weir.

Effects of weir geometry on scour development in the downstream of Piano Key Weirs [PDF]

Water Supply, 2020
Abstract Scouring in the downstream of all weirs, including Piano Key Weirs (PKWs), can have major safety implications. Since the research on downstream scouring of PKWs is very limited, and the weir geometry is also known to have an impact on downstream scouring, this study investigated scouring in the downstream of PKWs with ...

Monitoring Hydrological Processes for Land and Water Resources Management in a Mediterranean Ecosystem: The Alento River Catchment Observatory

Vadose Zone Journal, Volume 17, Issue 1, Page 1-12, 2018., 2018
Core Ideas Advanced sensor networks gather dense information on hydro‐meteorological variables. The Alento CZO helps assess the impact of climate and land‐use change on ecosystem services. Our research supports effective supply‐side and demand‐side adaptation strategies.

Evidence of Population Fragmentation of the Western European Hedgehog Erinaceus europaeus in Urban Landscapes

Ecology and Evolution, Volume 16, Issue 4, April 2026.
The Western European hedgehog (Erinaceus europaeus) is a declining mammal increasingly associated with urban landscapes. This study uses 1413 SNP markers to investigate the species' genetic structure and connectivity in Greater London, UK, and surrounding areas.

Integrating Satellite Data Into Meso‐Scale Habitat Modeling for Non‐Perennial Rivers and Streams

Water Resources Research, Volume 62, Issue 3, March 2026.
Abstract Non‐perennial rivers and streams (NPRs) are widespread and projected to become more common, yet effective tools for their characterization and management remain limited. This study introduces a novel approach to assess aquatic habitat availability in NPRs, applied to a regulated reach of the Sangone River (Northern Italy).

Prediction of the discharge capacity of piano key weirs using artificial neural networks

Journal of Hydroinformatics
The discharge capacity of the piano key weir (PKW) is an important flow feature which ultimately decides the design of PKWs. In the present research work, the different architecture of artificial neural networks (ANNs) was employed to predict the ...

Experimental and Simulation Studies on Water Discharge Coefficients of Rectangular Piano Key Weirs

International Journal of Technology, 2022
The piano key weir (PKW) is a developed type of labyrinth spillway with the ability to transfer large amounts of discharge by keeping executive costs constant.
