Background
During the late spring and early summer, a semi-permanent frontal boundary—called the meiyu front—emerges across eastern China, Taiwan, and Japan. This feature leads to prolonged periods of heavy rain and thunderstorms which frequently cause damage. Rainfall along this boundary tends to be particularly heavy in post-El Niño summers such as the summer of 2016.
Many lakes in cities had been turned into land in the development process of modern cities. Because of the enormous demand for food and housing in China, the natural drainage system has been damaged, water logging leading to problems in inner city development.
Many dams have been built along the Yangtze river, reducing the amount of water which could flow through the river.
