3. Trend Analysis of Highly Cited Papers on Sustainable Watershed Management: A Bibliometric Review

Surface and sub-surface flow and storage characteristics are inducing an acute need to study them in a sustainable manner in terms of their quantitative and qualitative approach. Rural and urban patches all over the world are facing drastic and severe demand of water resources that enables them to sustain life. Salinity, inorganic and organic contamination, high groundwater fluctuation, drying of river bed, etc., emphasise to conduct a bibliometric analysis to identify the research gaps and elimination of evils effects from water resources. The data for this study has been download from Science Citation Index Expanded from the years 1956–2018. The database has been analysed using the Mann Kendall test in XLSTAT software. The analysis showed that most of the research works are related to water pollution and Asian countries are increasingly executing the projects related to it. Laboratory method and modelling techniques are now predominant to conserve time and cost. The outcome of the paper shows remarkable improvement in watershed management studies. But more and more sustainable techniques are needed to remove the evils of vulnerability with due respect to water crisis.
