Spatial and temporal changes of runoff in the Yellow River in recent 15 years

Abstract In this study, the runoff data from 12 representative stations in Yellow River 2005 to 2020 is utilized, and Mann-Kendall trend test used examine changes observed of River. The results show that annual has grown upper reaches gradually reduced along river flow direction. It because mainly affected by precipitation human activities. addition, mutation each hydrological station not consistent. This may be caused many factors, resulting complexity changes. findings can reveal sequence variation provide a theoretical basis for management.
