Research areas of the most cited articles at Journal of Hydraulic Research:

The journal publications are mainly concerned with subjects like Mechanics, Geotechnical engineering, Turbulence, Hydrology and Flow (psychology). The studies tackled in the published articles, which mainly focus on Mechanics, apply to Classical mechanics as well. The journal articles deal with Geotechnical engineering in conjunction with Hydraulics and similar fields in Bedform.

What topics the last edition of the journal is best known for?

• Quantum mechanics
• Mechanics
• Statistics

The previous edition focused in particular on these issues:

Journal of Hydraulic Research facilitates discussions on Mechanics, Turbulence, Flow (psychology), Open-channel flow and Geotechnical engineering. Free surface, Flow (mathematics), Computer simulation, Vortex and Volume of fluid method are some of the study areas of Mechanics discussed. The research on Turbulence featured in Journal of Hydraulic Research combines topics in other fields like Compressibility and Flume.

While it focused on Flow (psychology), it was also able to explore topics like Jet (fluid), Calibration and Reynolds number. Topics in Open-channel flow explored in it were investigated in conjunction with research in Froude number and Emergent vegetation. The concepts on Geotechnical engineering presented in the journal can also apply to other research fields, including Dike, Erosion and Hydraulic machinery.

The most cited articles from the last journal are:

• Mechanism of low frequency high amplitude pressure fluctuation in a pump-turbine during the load rejection process (12 citations)
• Experimental analysis for self-cleansing open channel design (6 citations)
• Towards an evaluation of bedload transport characteristics by using Doppler and backscatter outputs from ADCPs (4 citations)

Papers citation over time

A key indicator for each journal is its effectiveness in reaching other researchers with the papers published at that venue.

The chart below presents the interquartile range (first quartile 25%, median 50% and third quartile 75%) of the number of citations of articles over time.

Publication chance based on affiliation

The publication chance index shows the ratio of articles published by the best research institutions in the journal edition to all articles published within that journal. The best research institutions were selected based on the largest number of articles published during all editions of the journal.

The chart below presents the percentage ratio of articles from top institutions (based on their ranking of total papers).Top affiliations were grouped by their rank into the following tiers: top 1-10, top 11-20, top 21-50, and top 51+. Only articles with a recognized affiliation are considered.

During the most recent 2021 edition, 5.21% of publications had an unrecognized affiliation. Out of the publications with recognized affiliations, 25.27% were posted by at least one author from the top 10 institutions publishing in the journal. Another 8.79% included authors affiliated with research institutions from the top 11-20 affiliations. Institutions from the 21-50 range included 21.98% of all publications and 43.96% were from other institutions.

Returning Authors Index

A very common phenomenon observed among researchers publishing scientific articles is the intentional selection of journals they have already attended in the past. In particular, it is worth analyzing the case when the authors participate in the same journal from year to year.

The Returning Authors Index presented below illustrates the ratio of authors who participated in both a given as well as the previous edition of the journal in relation to all participants in a given year.

Returning Institution Index

The graph below shows the Returning Institution Index, illustrating the ratio of institutions that participated in both a given and the previous edition of the conference in relation to all affiliations present in a given year.

The experience to innovation index

Our experience to innovation index was created to show a cross-section of the experience level of authors publishing in a journal. The index includes the authors publishing at the last edition of a journal, grouped by total number of publications throughout their academic career (P) and the total number of citations of these publications ever received (C).

The group intervals were selected empirically to best show the diversity of the authors' experiences, their labels were selected as a convenience, not as judgment. The authors were divided into the following groups:

• Novice - P < 5 or C < 25 (the number of publications less than 5 or the number of citations less than 25),
• Competent - P < 10 or C < 100 (the number of publications less than 10 or the number of citations less than 100),
• Experienced - P < 25 or C < 625 (the number of publications less than 25 or the number of citations less than 625),
• Master - P < 50 or C < 2500 (the number of publications less than 50 or the number of citations less than 2500),
• Star - P ≥ 50 and C ≥ 2500 (both the number of publications greater than 50 and the number of citations greater than 2500).

The chart below illustrates experience levels of first authors in cases of publications with multiple authors.
