In case of flood in Wuhan, which area is not easy to be flooded?

Wuchang District is the most easily flooded area in Wuhan, followed by Jianghan District, Jiang 'an District and Hongshan District. Other areas are not easily flooded. The extreme rainfall in the main flood season in Wuhan has increased, which has the characteristics of large one-time total amount, high short-term intensity and easy disaster. Sudden and rapid rainfall combined with rapid rainwater runoff, low-lying areas are more likely to be flooded if the drainage outlet cannot accumulate water immediately.

Cause analysis of waterlogging in Wuhan main city

1, the extreme rainfall caused by climate change increases (the total amount is large, the short-term intensity is high and it is easy to cause disasters, and the drainage outlet cannot accumulate water for a short time)

2. Wuhan's special topographical conditions are not conducive to urban drainage (the low-lying areas in urban areas are lower than the average flood level of the Yangtze River and the Hanjiang River, and the flow rate is slow).

3. The drainage facilities have the problems of low standard and small caliber (the secondary branch pipe network has not been completely upgraded).
