Effective Population Size Estimation in Large Marine Populations: Considering Current Challenges and Opportunities When Simulating Large Data Sets With High‐Density Genomic Information

Evolutionary Applications, Volume 18, Issue 8, August 2025.
ABSTRACT Next‐generation‐sequencing has broadened perspectives regarding the estimation of the effective population size (Ne) by providing high‐density genomic information. These technologies have expanded data collection and analytical tools in population genetics, increasing understanding of populations with high abundance, such as marine species ...

Effects of Short‐Term Climate Variations on Young Water Fraction in a Small Pre‐Alpine Catchment

Water Resources Research, Volume 60, Issue 10, October 2024.
Abstract Continuous and extended observations of hydrometeorological parameters, alongside the analysis of the isotopic composition across diverse waters within catchments, can significantly enhance our understanding of the potential ramifications of climate change on the hydrological response.

Population Genomics of the Blue Shark, Prionace glauca, Reveals Different Populations in the Mediterranean Sea and the Northeast Atlantic

Evolutionary Applications, Volume 17, Issue 9, September 2024.
ABSTRACT Populations of marine top predators have been sharply declining during the past decades, and one‐third of chondrichthyans are currently threatened with extinction. Sustainable management measures and conservation plans of large pelagic sharks require knowledge on population genetic differentiation and demographic connectivity. Here, we present

Piano Key Weirs: the experimental study of an efficient solution for rehabilitation [PDF]

WIT Transactions on Ecology and the Environment, 2010
The Piano Key Weir (PKW) is a particular geometry of weirs associating with a labyrinth shape and the use of overhangs, which reduce the basis length. The PKW could thus be directly placed on a dam crest. Together with its important discharge capacity for low heads (up to four times that of a Creager weir), this geometric feature makes the PKW an ...

EXPERIMENTAL COMPARISON OF FLOW ENERGY LOSS IN TYPE-B AND -C TRAPEZOIDAL PIANO KEY WEIRS (PKWS)

Journal of Engineering and Sustainable Development
As non-linear weirs with a high flow rate, Piano Key Weirs (PKWs) have attracted the attention of water engineers in recent years. Given the limited information available on the energy losses of these weirs, it is important to investigate the energy ...

Enhancing Hydraulic Performance and Discharge Efficiency of a Type-C Piano Key Weir Through Stage Incorporation

Journal of Engineering and Sustainable Development
Weirs are hydraulic constructions typically employed in dam spillways and channel control structures. The shape and size of the crest will determine whether the weir is linear or non-linear.

Conducting experimental and numerical studies to analyze the impact of the base nose shape on flow hydraulics in PKW weir using FLOW 3D [PDF]

Journal of Hydraulic Structures
Weirs serve as fundamental structures for channeling excess flow from behind dams to downstream areas. In this study, a numerical and laboratory investigation was conducted to explore the impact of different base nose shapes installed under the outlet ...

Hydraulic Advantage of Piano-key Weir Over Ogee Weir

International Journal of Innovative Technology and Exploring Engineering, 2019
The piano-key weir is a new encouraging hydraulic structure yet to become a widespread usage due to limited knowledge of the hydraulic performance. A laboratory investigation on the hydraulic efficiency of the piano-key weir was compared with that of an ogee weir.

Experimental investigation of the effect of the presence of obstacles at the end of the output keys of the C-type piano key weir on its downstream scour [PDF]

علوم آب و خاک
Piano key weirs are a type of non-linear weir that have a higher discharge coefficient than similar linear weirs. These hydraulic structures have a lightweight foundation and a simple structure is designed and installed on dams and drainage channels. Due
