Historical development of Yellow River regulation

Wang Jing's Harnessing the Yellow River

In the 12th year of Yongping, when discussing the management of Bianqu, the emperor summoned Jing Wong and asked about the geographical situation and convenient conditions for water control. Jing Wong stated the interests of water control, which was sensitive and quick, and was appreciated by the emperor. Because he used to manage military arts, he was awarded Shan Hai Jing, Hequ Shu, Yu Gong Tu and money, cloth and silk. In summer, the imperial court finally recruited hundreds of thousands of troops and sent Wang Jing and Wu Wang to build rivers and embankments, covering more than 1,000 miles from Xingyang to the mouth of Qiancheng. Jing Wong then surveyed the terrain, got through the hills, removed the sand and stones in the water, directly cut off the big ditch and deep stream, dredged and guided the stagnant water flow at key points (damming), and built a sluice every ten miles, so that the water flow could flow backwards and forwards, and there was no danger of breach. Although Jing Wong has saved the project cost, the cost is still calculated in tens of billions. The following summer, the canal was built. The emperor personally inspected it, and officials in charge of the river embankment were set up in Huanghe County, just like the system in the Western Han Dynasty. Jing Wong is famous for it.

The main reasons for the 800-year-old An Lan of the Yellow River after the Jing Wang River Regulation are as follows:

First, on the Yellow River, nomadic people retired from agriculture, and the vegetation was restored to a certain extent, which reduced the sediment entering the Yellow River;

The second is to open a new river to divide water and sand;

The third is to rectify the Yellow River levee;

Fourth, use low-lying land along the river to adjust water and sediment.
