Abstract:
The Tank Cascade Systems (TCSs) is found in dry and intermediate cli-
matic zones in Sri Lanka. Numerous professionals and researchers, both local and
international, have devoted considerable efforts to investigate and evaluate these sys-
tems. This study presents, comprehensive bibliometric performance analysis and vis-
ual scientific mapping of research trends related to TCSs in Sri Lanka, based on the
science direct database. Among 22 articles retrieved, 17 that were related to the TCSs
in Sri Lanka published in 2000-2023 period were selected for data analysis. The anal-
ysis was conducted using Excel and VOSviewer software, focusing on aspects such
as the country-wise contribution of international authorship, year-wise citations of
articles on TCSs in Sri Lanka, and the most commonly used keywords in the selected
articles. The Key words used for this study were “tank cascade system”, "cascade
system” and “Sri Lanka". The results revealed a significant international collabora-
tion, with contributions from 19 international authors and 38 national authors in the
field of TCSs. Notably, the highest levels of international authorship collaborations
occurred in 2017 and 2023. Australia made the most substantial international contri-
bution (36.84%). The most cited year among the selected articles was 2003. “A sim-
ple water balance modeling approach for determining water availability in an irriga-
tion tank cascade system” written by C.J. Jayatilaka, R. Sakthivadivel, Y. Shinogi,
I.W. Makin, and P. Witharana in 2003, was the most cited article in the field of TCSs
in Sri Lanka during the 2000–2023 period. Based on the analysis the most total link
strength keywords were ‘system’ (161) and ‘tank’ (119). These findings advance our
knowledge of TCSs research and may be useful in guiding future research for scholars
and practitioners
