Floods have a great impact on urban infrastructure, especially roads, railways, communications, embankments and other facilities. A city with infrastructure construction, according to a decade of flood prevention, or a hundred years of flood prevention, which are two completely different concepts. If in accordance with the situation of a hundred years to build, China's financial and material resources can not supported. As a result, whenever floods occur, the damage to the infrastructure is very large.

After 1949, in order to alleviate the threat of floods, began in the nationwide large-scale river regulation, development, revision of river flood control plan, carry out flood control construction.

To the end of the 20th century, the national total training, the new embankment, seawall 26 million km, built a number of flood diversion projects, opened up a row of flood storage area 98, with a focus on the regulation of the river, a total of more than 80,000 large and medium-sized reservoir. More than 2,000 large and medium-sized sluices.

In the early 1980s, the concept of non-engineering measures for flood control was introduced, and the construction of non-engineering measure was strengthened. The country has built more than 8600 water and rain flood stations, the use of computers, meteorological satellites and other high-tech means of observation, forecast floods. A series of flood control laws and regulations has been issued, such as water law, flood control law, soil and water conservation law, river management regulations and flood control regulations.

By the end of the 20th century, from the central to the local has been initially built with a certain basis for the flood control system. Yangtze River, the Yellow River, Huaihe River, Haihe River, Pearl River, Liaohe Songhua River and other seven rivers have been initially built to engineering measures and non-engineering measures as the main content of the flood control system. In the fight against the actual occurrence of the previous floods played an important role.

In the 21st century, China will continue to update the concept of flood control measures to further realize:

Strengthen and improve the flood control measures and flood control non-engineering measures in close connection.

To improve the level of operation and management of flood control projects, to ensure the safety of flood control under the premise of giving full play in the flood control project and the environmental benefits of comprehensive benefits for the sustainable use of water resources to make more contributions.

Accelerate the promotion of high-tech, as soon as possible to achieve flood control measures of information, digital, and constantly improve the hydrological and meteorological forecasting means to improve the level of flood forecasting and scheduling, flood control system to play a greater role.

With the development of economic society and science and technology, flood control measures should be continuously increased and increasingly perfect, in order to meet the requirements of flood control for socio-economic development.
