Background

Flood is a natural phenomenon that water quantity in rivers and lakes is rapidly increased or water level is rapidly increased due to natural factors such as rainstorm, rapid ice and snow melting, storm surge and the like, and is a natural disaster. Floods are generally classified into river floods, coastal floods, lake floods, and the like according to the areas of occurrence. Regulating water and managing water according to the season of water abundance and loss. In the years of excessive rainfall, whether flood causes disasters or not and the size of flood disasters can not be separated from human factors.

With the development of society, all rivers and lakes are basically developed and utilized by human beings, and river roads or lake-surrounding roads are basically built on the shore. When the flood comes in rainy season, the water level is often submerged after rising to destroy the infrastructures such as the surrounding roads.
