A Socio-Hydrological Unit Division and Confluence Relationship Generation Method for Human–Water Systems

Studies on human activities and the natural water cycle as a coupled system are essential for effective resource management in river basins. However, existing calculation methods based solely do not meet accuracy requirements of society dualistic simulations. Therefore, it is necessary to establish more scientific reasonable unit division method confluence relationship determination method. This paper presents socio-hydrological with dual characteristics both hydrological social administrative basin. According elevation buffer zone, relationships among units determined, upstream downstream human–water obtained. Finally, case study Jing-Jin-Ji region China, an area intensive activities, was performed. A reliability 94.3% reached using proposed method, suggesting that approach highly applicable. Thus, generating determining can be applied mutual influence spatial distribution cycles. The data requirement minimal, provide benefits research systems.
