摘要

Piano key weir (PKW) is a non-linear weir that increases discharge capacity while maintaining a reduced footprint, presenting an appealing solution for dam rehabilitation and reinforcing dam resilience against climate change. This paper extends a prior bibliometric analysis using VOSviewer with a scopus dataset up to February 8, 2024, to deeply explore the evolution of PKW studies. It particularly highlights the value of co-citation and co-occurrence tools in VosViewer for mapping the current state of research and collaboration networks within the PKW field, uncovering research gaps and identifying future opportunities. The analysis provides an overview of the multidisciplinary nature of PKW research, underlining significant work in hydraulic performance, design optimization, environmental considerations and the application of advanced computational models. This study traces the progression of PKW research methodologies, from foundational experimental studies to the most recent applications in computational fluid dynamics (CFD) and artificial intelligence (AI), indicating a dynamic evolution of the research in PKW. Ultimately, this research not only confirms PKW as an active and evolving field of study but also emphasizes the essential role of interdisciplinary collaboration and technological innovation in the advancement of PKW technology for sustainable water management.
