What is a pipe flood? Where do tubes usually occur, when?

Flooding is a natural phenomenon that occurs during the rainy season and only in mountainous areas, many people mistakenly believe that flood pipes are flash floods.

The process of forming flood pipes

Flooding caused many houses and structures in Muong Loi commune, Dien Bien district to be eroded and deeply submerged.

Because the terrain on the surface of the earth is uneven, in the mountains there are many hills and mountains interspersed and stretched; between them are valleys associated with small slots, streams and rivers. At the locations of streams and small rivers flowing through the two sides of the valley are closed, causing drainage lines to be narrowed and shrunk at 1 point, which is often the place for producing flood pipes. When the rains in the upstream are large, the water flows to many; The spasms that do not drain the water quickly make the water rise above and create a tight flow at the bottom of the constriction waist that will produce a flood of pipes.

When did the pipes flood?

Flooding can also occur in limestone areas, where often underground caves and reservoirs are connected to the outside by small, narrow ravines. When there is heavy rain, water concentrates quickly on underground lakes and caves, causing high water levels and high pressure causing flooding at the exit gates.

Flooding flooded the valley, especially devastating huge area below the door, sweeping everything encountered on the way.
