Abstract: Reconstruction of river runoff has been an important component of paleo-climatology and paleo-hydrology. The Yellow River and Yongding River are two major surface drainage systems in North China. In this paper, both of them were studied to reconstruct annual flood-season runoff from 1766 to 2004 at Sanmenxia station (Yellow River) and Lugouqiao station (Yongding River) using the water level records and Yu-Fen-Cun records in the Qing Dynasty documents and modern hydrological records. We reconstructed the annual flood-season runoff of Yellow River (Sanmenxia station) and Yongding River (Lugouqiao station), with the average of 109.0 m3/s (Yongding River) and 5121.1 m3/s (Yellow River), respectively. In this article, the extreme flood/dry years are reconstructed based on a new method. Based on the two runoff series, we find that the synchronization of the Yellow River and Yongding River existed in a specific period, and during 1840-1860s and 1890-1910s, the synchronization disappeared, and the inverse correlation was very obvious. The wavelet shows that there was a 30-year cycle in both of the rivers; however, after the 1920s the cycle disappeared in the Yongding River. On a 60-80a scale, the changing runoff of the Yellow River was earlier than that of the Yongding River. In MWP, the inverse correlation in the trend of the two rivers was more obvious. Warm period, PDO and sunspot number have affected the changes of river runoffs in North China.
