[Objective] The aim of this study is to explore the changes of runoff-sediment relationship at flood event scale in typical watersheds of the Loess Plateau, to discuss the regulation of runoff-sediment relationship by comprehensive management of soil and water conservation, and to provide reference for future ecological restoration and comprehensive management of soil and water conservation in the Loess Plateau. [Methods] We selected the Gushanchuan, Jialuhe and Xichuanhe watershed to explore the changes of runoff-sediment relationship at flood event scale in three watersheds. Based on their flood event data of 1974—1989 and 2007—2019, a linear model was used to analyze the changes of runoff-sediment relationship in different periods of three watersheds, the Pearson correlation coefficient method was used to investigate the correlation of runoff and sediment-related variables, and the driving factors of runoff-sediment relationship change in each watershed were identified. [Results] The runoff depths and sediment yields of flood events in 2007—2019 of each watershed significantly reduced（p＜0.05） compared with 1974—1989, and the greatest changes were observed in the Gushanchuan watershed, with a decrease of 56.48% and 95.03%, respectively. The change in the amount of sediment yield in the Jialuhe watershed was not obvious and the increase in runoff depth was mainly due to the low degree of vegetation restoration in the watershed, the relatively low impact of soil and water conservation measures, and the increase of rainfall in recent years. [Conclusion] After the implementation of soil and water conservation measures, the runoff-sediment relationship of each watershed had changed significantly, and the linear relationship between runoff depth and sediment yield had weakened, which was due to the implementation of soil and water conservation measures on the Loess Plateau, especially the large-scale vegetation restoration, which had reduced the sediment production and transportation capacity of the unit runoff depth in the watersheds, and resulting in the reduction of sediment into the Yellow River.

[Objective] The aims are to study the characteristics of precipitation, runoff and sediment transport in typical tributaries of Kongdui, quantify the impact of climate change and human activities on water and sediment changes, so as to reveal the driving mechanism of water and sediment evolution in Kongdui area, and to explore the reasons for the reduction of sediment transferring to Yellow River through Kongdui. [Methods] Based on annual precipitation, runoff and sediment discharge data from 1980 to 2018 in the Hantaichuan Basin, a typical tributary of the 10 Kongdui in the Yellow River Basin, the causes of water and sediment changes were investigated by means of linear trend method, Mann-Kendall trend test, Pettitt catastrophe test and double accumulation curve. [Results] Precipitation and runoff in Hantaichuan watershed showed a non-significant upward trend, while sediment discharge showed a significant downward trend (p＜0.05). The annual runoff and annual sediment discharge both changed abruptly in 1998. After the abrupt change, the annual average runoff decreased by 38.61% compared with that before the abrupt change, while the sediment discharge significantly decreased by 80.61% compared with that before the abrupt change. [Conclusion] Human activities are the main factors contributing to the decrease of runoff and sediment discharge in the Hantaichuan Basin, with the contribution rates of 60.38% and 59.73%, respectively, while the contribution rates of precipitation change are 39.62% and 40.27%, respectively.

The flood disaster adaptation of the Yellow River has always been a major issue for state administration and ensuring natio rity. The history of the Yellow River management can be regarded as the progresses of downstream flood control. This paper general duced the concepts and policies of the Yellow River management in history, and analyzed the characteristics of the Yellow River v tremely high spatial and temporal differences in water and sediment sources, and the incongruous process of water and sediment trans distinct river sections. Flood events with high sediment load in the middle reaches of the Yellow River is the main source of the down. floods. In view of the new situation of the dramatic changes in the Yellow River basin, we proposed several strategies for the Yellow Riv sin management. Firstly, enhance afforestation and grass plantation for soil and water conservation in the middle reaches of the Yellow R secondly, strengthen dredging of the downstream river channels and clean up riverbed sedimentation to protect the downstream river cha without silting; and finally protect the embankment and leave the flood flow own pathway.
