1998 flood, including the Yangtze River, Nenjiang River and Songhua River. The Yangtze River flood is one of the most serious floods in the whole basin in the 20th century, following the two floods of 193 1 and 1954. The floods in Nenjiang River and Songhua River are also the worst floods in the whole basin since 150 years.

According to preliminary statistics, including Jiangxi, Hunan, Hubei and Heilongjiang provinces, there are 29 provinces (autonomous regions and municipalities) suffering from floods to varying degrees, with the affected area of 3180,000 mu, the affected area of1960,000 mu, the population of 223 million, 4 150 deaths and 60 houses collapsed.

Extended data:

1998, another basin-wide flood occurred in the Yangtze River since 1954.

Since mid-June, the flow of the Yangtze River has increased rapidly due to the continuous heavy rain and heavy rain in Dongting Lake and Poyang Lake. Affected by the upstream inflow and flood season, the tidal level along the Yangtze River in Jiangsu Province has exceeded the warning level since June 25th. The climax of Nanjing Station is located on July 6th, reaching 9.90 meters.

The area along the Yangtze River in southern Jiangsu entered Mei from June 24th to July 6th. Because of the high tide level along the river, the drainage of inland river is blocked, which has formed a severe situation of flood disaster. The highest water level at Dongshan Station of Qinhuai River 10.28m is the third in history. The highest water level at Xiaoqiao Station of Chuhe River reached 1 1.29 m, which exceeded the warning water level 1.79 m. ..

From late July to early September, influenced by seven consecutive flood peaks in the upper reaches of the Yangtze River and the confluence of tributaries in the middle reaches, the maximum flow of Datong Station reached 82,300 m3/s on August 2, second only to the flood peak flow 1954, ranking second in history.

On July 29th, the highest tidal level at Nanjing Station was 10. 14m, ranking second in history, and it lasted for 17 days above/kloc-0.0m. The high tide level at Zhenjiang Station on August 24th was 8.37m, only lower than 1954/kl. [ 1]?

1998 compared with the historical flood, the main difference is that the flood peak water level in the middle and lower reaches of the Yangtze River and the main control stations of Dongting Lake and Poyang Lake during the flood of 1998 is obviously higher than the long-term high water level; Reduce flood diversion and breach.
