Why can a rainstorm drown Wuchang?

Natural conditions and urban planning and construction can cause a rainstorm in Wuchang.

1. Natural conditions: Wuchang is located in Jianghan Plain and belongs to the middle reaches of Hanjiang River system. Because of the low terrain, numerous water systems, heavy rainfall and strong concentration, and the unclogged sewage pipes, it is easy to cause waterlogging, especially in heavy rain.

2. Urban planning and construction: The construction density in Wuchang area is high, and the municipal infrastructure is still defective, lacking effective drainage facilities, such as rainwater collection wells, rainwater gardens, and municipal drainage networks. As a result, rainwater cannot be discharged quickly, leading to urban waterlogging.
