With the rapid development of hydropower exploitation in China, changes in runoff and sediment transport have become a significant issue that cannot be neglected.
In this study, the Han River was selected as a study case, where the runoff variation and changes in sediment load at the Baihe, Huangjiagang, Huangzhuang, and Xiantao stations were analyzed in different time periods.
The results indicate that impact of cascade hydropower exploitation on runoff and sediment transport is significantly different even during the same time periods.
After reservoir regulation, the decreasing of sediment load is faster than that of runoff.
Strong positive correlation between runoff and sediment load exists during different time periods, while reservoir operation leads to different turning points at the Baihe, Huangjiagang, Huangzhuang, and Xiantao stations in the middle and lower Han River.
As a key driving factor, runoff variation contributed to sediment transport with different impact index CR.
The impact index CR before and after the first change point at the Baihe, Huangjiagang, Huangzhuang, and Xiantao stations is 43.35%, −3.68%, 11.17%, and 30.12%, respectively.
This study helps us understand and evaluate the hydrological changes under cascade hydropower exploitation in the middle and lower Han River.
