1998 what is the relationship between the catastrophic flood and Jiujiang levee? If yes, please explain, if not, how bad is the levee?

Ming Lu, deputy mayor of Jiujiang Municipal People's Government and city flood control commander: This dike was built by 1966, and there was no clear foundation at that time. 1995 in order to improve the flood control standard, the city raised funds to build a flood control wall on the original earth embankment. Because the construction started in April, the flood season was approaching and the construction period was tight, so the foundation cleaning was not carried out. "The flood is coming, the embankment is unstable, and the weak section is washed away!

Jiangxi, Hunan, Hubei and Heilongjiang provinces are the hardest hit areas, and 29 provinces (autonomous regions and municipalities) have suffered from floods in different degrees. The affected area is 3180,000 mu, the disaster area is1960,000 mu, the population is 223 million, 4 150 people died and 688,438 houses collapsed.

Extended data:

Due to siltation, reclamation and other reasons, the area of lakes in the middle and lower reaches of the Yangtze River has decreased, which has reduced the flood regulation capacity of lakes in the middle and lower reaches of the Yangtze River, and the flood storage capacity of lakes has decreased year by year. Many Tongjiang lakes are no longer connected with rivers, and rivers and lakes are isolated. The beaches and passages that once flooded can't be flooded now. Coupled with the serious obstacles in the river, the cross section of the river is narrowed, the flood outlet is reduced, the drainage is not smooth, and the flood travels slowly.

Moreover, the diversion ratio of the three ports of the Yangtze River (Songzikou, Taipingkou and Ouchikou) to Dongting Lake has dropped from 45% in the 1950s to about 25%, which has increased the flood control pressure of the main stream.
