What does a flash flood mean What does a flash flood mean?

A flash flood is a swelling flood that occurs in a mountain stream.

Mountain floods are sudden, the water is concentrated and the flow rate is large, the erosion is destructive, and the water flow carries sediment and even stones, etc., which often causes local floods, which are generally divided into torrential rain mountain floods, snowmelt mountain floods, glacial mountain floods, etc.

Flash flood is a phenomenon of rapid and powerful surface runoff that occurs in mountain streams, and refers to the surface runoff that occurs in small ravines or barren streams with periodic flow in mountain basins, which lasts for a short period of time and rises and falls.

The water level of the mountain stream suddenly soared, carrying sediment and rushing down the mountain, which was extremely destructive.

Flash Floods: Floods in the mountains remained. It seems to be.

Sudden flooding in a mountain ravine. Flash floods are sudden, with concentrated water and high flow velocity and strong erosion destructive power.

Flash floods are special floods in hilly areas, and the masses are accustomed to calling them"Fa Jiao"。Flooding generally lasts from a few dozen minutes to 1 2 hours. The main conditions for formation are as follows:

1. Topographic conditions: Generally, the topographic characteristics of mountain floods and debris flows are medium and high mountainous areas, with large relative elevation differences and steep river valley slopes. The surface layer is covered with thick soil with grafting, and the bottom layer of the soil is a broken rock layer cut by medium-deep faults and their derivative faults.

2. Forest cover conditions: a wide range of forests and moso bamboo cover, when the humid air carries a large amount of water vapor in the flood season, it reaches the air above the forest area, and the cold air with low temperature and high relative humidity in the forest area is easy to cause large local precipitation.

3. Water source conditions: water rest is not only a component of flash floods and debris flows, but also a triggering factor, mainly from rainfall.

The phenomenon of rainfall triggering flash floods is the combined effect of previous rainfall and a continuous rainfall. Second, the early rainfall and the maximum hourly rainfall play a leading role in stimulating it. The water content of the soil on the top of the mountain is saturated, and the pressure of the pressurized water body in the cracks of the rock layer below the soil increases sharply.

In the event of heavy rain, energy accumulates rapidly; As a result, the original soil balance is destroyed, and the pressurized water body in the cracks of the soil and rock layer breaks through the surface cover, and instantly pours down from the middle and upper part of the mountain, causing flash floods and debris flows.

When the humid airflow is blocked by the mountain, the humid airflow will move upward, forming cold and warm fronts on the mountaintop and windward slope to produce thunderstorms. Because the middle and upper part of the mountain stretches into the clouds, the ground is still very hot, and when the mountain rain is about to come and the wind is full, the middle and upper part of the mountain is already in two layers. So often the rain on the ground is not long.

Then the flash flood broke out. The experience of villagers in flash flood-prone areas is particularly muggy, often the same"Fa Jiao"Together.

In addition to the structural conditions of the mountain, the cause of flash floods is mainly caused by the topography of the trumpet-shaped estuary, which forms short-duration thunderstorms and causes flash floods.

Floodwaters from the mountains flowed down.

Storm is rage, storm is torrent.

The storms of flash floods are: 1. **, cruel; 2. Impatience; 3. Sudden and violent.

Heavy flooding in the mountains caused by heavy rainfall.

The flood water from the mountains flowed down violently.

Outbreaks are mainly used for sudden and violent attacks, mostly caused by external conditions, mostly for specific natural objects related to water, and often used in conjunction with people and things that suddenly become rich or powerful. Flash floods are specific natural objects related to water, and flash floods are caused by the external condition that the rain is large and concentrated, so the outbreak is used.

Eruption can refer to the sudden breakout of the earth's crust by the magma inside the volcano, describing the sudden onset and sudden rise, or it can also be compared to the sudden and rapid occurrence of gunpowder**, which has a wide range of applications, such as the sudden appearance of loud noises and major events.

Difference Between Explosion and Storm:

1. The reference is different.

Explosion: Burst suddenly. Storm: Sudden and violent.

2. The source is different.

Burst, scorch. From the fire, the storm sounds. Vernacular Interpretation:

Burst, burn. The glyph uses "fire" as the side, and "storm" is the sound side. Storm:

Xi also. From the day, from the out, from the squeak, from the meter. Vernacular Interpretation:

Storm, sunshine. The glyph adopts the four-form meaning of "sunrise rice".

3. The nature is different.

Explosion: Shape sound. From the fire, the storm sounds. Original meaning: to explode and make a sound. Storm: The word will be meaningful, from the sun from the rise from the rice, originally refers to the two hands of agricultural tools in the sun to dry rice.

Flash floods. "Outbreak" and "outbreak" are both verbs, and both contain the meaning of "sudden onset". Outbreaks are sudden and violent, with a narrow scope of application, and are mostly connected to water-related things, such as flash floods and floods.

But a flare-up also indicates a sudden onset or manifestation of an individual's strength, emotions, etc. And the outbreak has no such usage. In addition, outbreak also refers to the use of improper means to suddenly gain power and wealth, which is a derogatory term.

And Burst has no such usage. <

The meaning of the sudden inclination of the flood.

The "storm" in "flash flood" is used here as an adjective as a verb, which means that the momentum is fierce. "Flash flooding" means that there is a sudden flood in a mountain stream.

Flash floods are sudden, the water volume is concentrated, the flow velocity is very large and the destructive power is also very strong, and the water flow carries sediment and even stones, etc., which often causes local floods.

Areas with a high probability of flash floods should heighten their vigilance at any time after entering the flood season, firmly establish the idea of "strict precautions and unremitting preparedness," and be people-oriented and safety first.

Therefore, it is necessary to listen to and watch meteorological information and disaster forecasts issued by higher departments frequently, pay close attention to and understand the changes in rain and water conditions in the locality, and be well aware. In particular, residents whose residence belongs to the dangerous area must carefully familiarize themselves with the location of their residence and the potential situation of flash floods in advance, and determine the route and place of emergency measures and safe transfer; It is also necessary to be diligent in observing whether there are mountain cracks, subsidence, tilting and local displacement changes in front of and behind the house; Whether there is turbidity in the well water and the phenomenon of muddy water suddenly rising on the ground; Whether there is an abnormal reaction in animals and plants, etc.

If you find a clear precursor, you should evacuate the scene quickly and decisively. Residents living in the warning area should also be prepared for emergency rescue and disaster relief and safe transfer at any time, especially cash should be deposited in the bank as much as possible and not hidden at home.

Flash floods are a catastrophic phenomenon caused by the formation of extreme weather such as torrential rain and blizzard in mountainous areas when a large amount of rainfall or melted snow flows to rivers, streams and other waterways, resulting in a sharp rise in river water levels, faster flow speeds, and increased impact on water bodies. Specifically, here are some of the causes of flash floods:1

Heavy rainfall: Rainfall exceeds what the local hydrological system can handle, causing rivers to reach rapidly**, resulting in flash floods. 2.

Geological formations: Geological hazards such as **, landslides, and debris flows may alter the hydrological characteristics of rivers, which in turn can lead to flash floods. 3.

Glacial lake dam failure: In high-altitude mountainous areas, glacial lake dikes are prone to collapse due to glacial melt and rainfall, resulting in reservoir dam failure and flash flooding. 4.

Deforestation and land-use change: Deforestation leads to loss of soil and water conservation capacity, and soil erosion is susceptible, affecting the hydrological environment of mountainous areas and breeding flash floods. 5.

The natural conditions of the river are harsh: the river is narrow and steep, the flow speed is fast, the gradient is large, and the impact of the water flow is strong, which is easy to cause flash floods. It should be noted that flash floods are an extremely dangerous natural disaster that causes huge losses to people's lives and property.

Therefore, the prevention and mitigation of the impact of flash floods is of great significance for the residents and economic development of mountainous areas.
