The causes of flood disaster, the difference between rainstorm and flood disaster.

The causes of floods are generally excessive natural precipitation or untimely drainage. The main differences between rainstorm and flood are: different definitions, different hazards and different protective measures.

I. Different definitions

1. Flood: Flood is a natural phenomenon. Refers to the phenomenon that low-lying areas are flooded and waterlogged due to heavy rain, heavy rain or continuous rainfall.

2. Rainstorm: Rainstorm is a kind of natural weather, and it is rain with great precipitation intensity. It is raining cats and dogs. Generally, it refers to the precipitation with hourly rainfall greater than16mm, or12h continuous rainfall greater than 30mm, or 24h continuous rainfall greater than 50mm.

Second, the harm is different.

1. Flood disaster: it mainly harms the growth of crops, resulting in reduced or no crops, undermining the normal development of agricultural production and other industries, endangering the safety of people's lives and property, and also leading to the epidemic of infectious diseases.

2. Heavy rain: Long-term heavy rain is likely to produce stagnant water or runoff to flood low-lying areas, resulting in serious soil erosion, reservoir dam failure, river flooding, houses washed away, farmland flooded, traffic and telecommunications interrupted, which will bring serious harm to the national economy and people's lives and property.

Third, the protection measures are different.

1. Flood: timely forecast and build water conservancy projects.

2. rainstorm: check the house. If it is a dangerous old house or a low-lying place, move out in time. Check whether the circuits and fire fighting facilities are safe, and turn off the main power switch. Don't wait in the car when the car stalls in a low-lying place. Get off at a high place and wait for rescue.
