Socio-hydrology is a new inter-disciplinary science of people and water. The biblio-metrical analysis was made on the socio-hydrology papers included in the Web of Science (WoS) to obtain the study progress of socio-hydrology. The results indicated that the research areas of socio-hydrology mainly covered water resources, environmental sciences, civil engineering, geosciences, environmental engineering, agronomy, environmental studies, ecology, meteorology and atmospheric sciences, and geography. The key topics in general socio-hydrology were water resources, agricultural irrigation, and water policy. Furthermore, the research spots varied with the needs of the societal development in the different decades. They also varied among countries. The special socio-hydrology research mainly focused on water need and security in both urban and rural development, and emphasized the decision support of scientific management through effective hydrological model prediction. Its development will promote the sustainable management and utilization of water resources and help better solve water problems facing the humans.
