In July 1958, the peak discharge of the Yellow River at Huayuankou was Шаблон:Convert with a maximum sediment concentration of Шаблон:Convert, 14× and 24× their mean annual values, respectively.[1] The flood water level was so high that it rose up to the top of the levee in several places.[2]
This flood affected 741,000 people, submerged over half a million acres of crops (3.04 million mu), and destroyed over 300,000 houses in 1708 villages.[3] It was reported as the most severe flood since 1933.
