Use of Computerized Bibliometric Systems to Analyse 20-Year Trends in the Field of Environmental Groundwaters: An E-Programme Simulation Study

Abstract

Objective: To map out the thematic areas, methodological approaches, and evolution of environmental groundwater research over 20 years, identifying key trends, collaborative networks, and emerging research clusters that have shaped the field. Identify trends in the field over the last 20 years to inform subsequent studies

Methods: Using CiteSpace 6.2.R2, a comprehensive bibliometric analysis was conducted on 2475 documents, focusing on keyword co-occurrence, clustering, and burst analysis. The study also examined co-authorship and co-citation networks to understand the structure and dynamics of the research community.

Results: The study identified several key research clusters, including Heavy Metals, Risk Assessment, and Pollution, indicating a focus on contamination effects and mitigation strategies. Innovative research areas like Self-Healing and Magnetic Resonance Sounding have emerged, highlighting advancements in materials and geophysical methods. The research has progressively integrated interdisciplinary methodologies, with recent trends emphasizing technological approaches like numerical simulation for enhancing groundwater management.

Conclusions: Over two decades, environmental groundwater research has evolved from basic contaminant studies to sophisticated, interdisciplinary approaches that integrate cutting-edge technologies. This progression underlines the increasing complexity and scope of challenges faced in groundwater management and suggests future directions involving more integrated and technologically driven solutions.
