Water conflicts occur between countries, states (provinces), groups and other different stakeholders over the access to water. Since the end of the Cold War, the overall intensity of water conflict related events has declined, and the number of events has increased significantly. Meanwhile, researches on water conflicts has begun to gain widespread attention. This paper uses unsupervised machine learning, spatial analysis and data visualization methods to sort out the researches on water conflicts and summarizes the main topics of water conflict research. It is found that water conflict related research have obvious spatial heterogeneity, and the evolution trends of different topics in time vary; the main topics of water conflict related research include: causes, analysis methods and models, conflict resolution mechanisms, the impact of climate change, water hegemonism and international water law.
