Floods are created when a huge volume of water moves rapidly from high to low, causing inundation, destroying terrain, property and potentially taking the lives of many people.

What is flash flood?

Flash floods are a natural phenomenon that occurs during the rainy season and usually only occur in mountainous areas, small basins, and areas with closed terrain surrounded by high mountain ranges.

In the mountainous areas, there are many interwoven and long ranges of hills, in the middle are valleys with streams, small rivers and creeks. In the locations where streams and small rivers flow through both sides of the hills, the valley is closed, causing the drainage to gradually narrow and constrict at one point. When it rains heavily upstream, a lot of water flows down and cannot drain in time at the constriction point, causing the water level to rise rapidly above, creating a rapid flow below the constriction, which will cause flash floods.

Basically, flash floods are like other types of floods, formed by water falling suddenly from above, creating great destruction downstream, possibly sweeping away everything in its path.

It is worth noting that flash floods appear with strong currents and extremely dangerous whirlpools.

What is flash flood?

Flash floods are a type of flood that is formed when a huge volume of water moves rapidly from high to low terrain. This large volume of water is formed by thunderstorms, tropical storms, a large volume of ice on the mountain suddenly melting or by a dam breaking or releasing floodwaters in a hurry with a volume of thousands of cubic meters per second.

Flash floods are extremely destructive, especially when the slope is steep and the flow is not much obstructed. People have been cutting down trees indiscriminately, leaving many forests bare. Therefore, if a flash flood occurs, the flow will be faster and stronger, creating even greater destruction.

Flash floods often appear near hills and mountains, flowing into valleys, sweeping away all obstacles on the road, including houses.

It is noteworthy that when the giant water flow from above at high speed meets great resistance, it will bounce back and hit the incoming water, creating many whirlpools that suck everything around, making the water level rise faster and more dangerous.
