abandoned in 1041. Only seven years after the project to restore the river's course was ended, the Yellow River flood of 1048 caused the river to move much further north, meaning that the Chihe, You, and Jin rivers were no longer a threat to agriculture around modern-day Hebei and Shandong. Due to the flooding of agriculture in Dezhou and Bozhou, as well as the sediments carried along the Yellow River's three new tributary rivers, the 1034 flood was recorded as reducing the revenues of the northern provinces by half. The economic consequences of the first flood however were not fully repaired by the time that the second flood came, leading to yet more devastation in the northern provinces of the Northern Song.
