China is Building an”Iron Wall” to Cope With the Flood Season

Since the flood season, rainstorm and flood occurred frequently in southern China. More than 400 rivers in the country had floods above the warning level; the Yangtze River, the upper reaches of the Yellow River, the Xijiang River and Beijiang River, Taihu Lake and Huaihe River successively experienced huge floods. At present, the water level of Poyang Lake has broken through the historical height in 1998, and the “No.2 flood of Yangtze River in 2020” has been formed in the upper reaches of the Yangtze River. The water level of Taihu lake rises to the guaranteed level and is expected to continue to rise slowly. Hubei, Jiangsu and other places have started flood level I emergency response, and the flood situation is extremely severe.

In the face of this year’s flood situation, many people compare it with the catastrophic flood in 1998. Although the average precipitation in the Yangtze River Basin since June has reached 369.9 mm, 54.8 mm more than that in the same period in 1998, which is the highest in the same period since 1961, but the losses caused by floods in various regions are lower than those in that year. One of the important reasons is that China’s comprehensive flood control and flood fighting capacity is not what it used to be: 121,000 hydrological stations monitoring, 312,000 km of levees above grade 5 for retaining water, 98,800 large and small reservoirs for regulation.

There is a group of data worthy of attention: compared with the same period in the previous five years, the number of people affected by the flood disaster decreased by 7.3%, the number of collapsed houses decreased by 69.3%, and the direct economic loss decreased by 9.4%.


In recent years, China has paid more attention to the construction of water conservancy facilities and built a “iron wall” firmly, which makes the flood control and drought relief system more effective.
