China is once again drenched in the rain. While nobody likes the rain, in this country it has gone from mild annoyance to serious problem. With more than 100 cities with populations over one million, China has experienced a significant problem - flooding - due to all the construction on former farmland. Instead, China is upgrading its cities to welcome the water rather than block it, rather than constructing significant barriers like others have done. Take in China's sponge cities while you are comfortable. Let's begin.

In urbanization, natural drainage systems are often replaced with artificial ones, which results in urban flooding. The problem is further exacerbated by land cover change accelerating runoff, the concentration of population and property, and possible local climate change. The recent rapid urbanization in China is also viewed as directly responsible. The frequency and impact of China's floods are related to local rainfall. Chinese investments in flood control since the devastating floods of the 1990s have not been beneficial to many cities that suffer from pluvial flooding, as those investments have focused almost exclusively on fluvial flooding.
