What kind of disaster is flood? What kind of disaster is flood?

Floods are caused by meteorological factors such as continuous heavy rains and are meteorological disasters.

Flood disasters include flood disasters and rainwater disasters. Among them, disasters caused by heavy rainfall, melting of ice and snow, ice, dam breaks, storm surges, etc., which cause rivers, lakes and coastal areas to increase water volume, rise in water levels and cause flooding, as well as flash floods, are called flood disasters; disasters caused by heavy rain, heavy rain or long-term rainfall Disasters caused by excessive concentration of water and runoff, and failure to drain water in a timely manner, causing land and houses to become waterlogged and flooded, are called rainwater disasters. Since flood disasters and rainwater disasters often occur simultaneously or continuously in the same area, they are sometimes difficult to accurately define and are often collectively referred to as flood disasters.

Flood disasters will cause great damage to the environment on which human beings depend for survival. For example, floods cause water and soil erosion every year. A large amount of soil and its nutrients are lost, resulting in barren land. At the same time, the sediment content in the water flow increases, leading to the decline of river functions, shrinking lakes, and desertification of cultivated land. The serious consequences are inestimable.

Major flood disasters will cause a large amount of farmland to be washed away and submerged, and crop production will be reduced or even eliminated. The agricultural product processing industry, light industry, etc. will lack raw materials or the cost of raw materials will increase, causing factories to reduce or suspend production, and then workers will lose their jobs.

Major flood disasters will also reduce the living standards of the people in the disaster areas and lack basic living security. There will be a large number of disaster victims, disrupting the normal social order and affecting all aspects of society.
