The AD 1034 Yellow River flood was a natural disaster along China's Yellow River originating in a burst fascine at Henglong in the territory of the Northern Song dynasty. It divided the Yellow River from its previous course into three more northerly channels meeting the Chihe, the You, and the Jin. The flood was recorded as reducing the revenues of the northern provinces by half, damage that had not been repaired before the even-larger 1048 flood at Shanghu again devastated the area.
