Causes and Dangers of Floods

flood damage

Floods are a natural calamity that comes with so much destruction. Floods occur when water bodies

have an increase in water level thus causing them to rise and overflow onto dry land. Floods have

been around from time immemorial and in some cases, some could say that some instances of

flooding have been an ‘advantage’ as it carries fertile soil and deposits it elsewhere making the area

more fertile. However, as much as the area where the soil has been deposited becomes more fertile,

the area where the soil was brought from by the floodwater is often left with no that

connection, floods have been seen to be more of a menace than an advantage. It is unfortunate to encounter floods, but it is still important to repair floods. AlorAir®Storm Elite commercial repair dehumidifier can reduce the cost of flood repair.


Causes of floods

  • Rainfall and melted snow

Rainfall is the go-to cause when one hears of a flood. Extremely heavy rainfall especial that

was unexpected and unprepared for can cause the affected area to flood most cases areas that

are low lying plains and have loam or clay soil is most likely to experience worse floods.

For areas surrounded by with icy peaks, flooding is very likely to occur as the ice may melt during hot

seasons causing water to flow into the surrounding areas this water will, in turn, accumulate at the

the base of the mountain leading to flooding in that area.

  • Thunderstorms

These are a very notorious cause of flash floods. They cause small fast-moving rivers to swell up to

ten times its original size thus making them burst their banks and overflow into its unsuspecting

environs. Thunderstorms may at times cause tides to rise more than usual causing the surrounding

area to flood.

  • Tsunamis, cyclones, and hurricanes.

Coastal regions are affected mostly by floods through earthquakes that occur in the sea beds causing

thereto be gigantic waves which in turn overflow to the coastal region causing it to flood, this is

called a tsunami. Hurricanes and cyclones also begin in large water bodies. These extra strong winds

move across the ocean collecting water as it moves towards dry land at abnormal speed and with a

lot of force. The cyclones then dump the water it was carrying onto the dry land causing it to flood.

  • Human activities

Destruction of forests and other vegetation covers for commercial use without replacing it can be a

cause of flooding. Trees and other vegetation use water for photosynthesis and survival; thus they

absorb water using their roots into the plant. This process, in turn, prevents stagnation of water.

Thus, the more we cut down trees, the less they become leading to flooding. Humanmade dams once

left unmanned, and its pressure levels increase will break under pressure causing the water to pour out

and flood its surrounding areas. Dams can also cause floods if they are left to fill beyond its holding capacity.

  • Poor drainage systems

This is a problem experienced mostly in third world countries where the drainage system is poor and

unmaintained thus it is unable to handle even the slightest rainfall. This is however very preventable by

collecting the rainwater for use elsewhere and installing effective underground drainage systems. If the house is eventually damaged by water accidentally, use a dehumidifier and fan to repair it. AlorAir® Storm Ultra dehumidifier and Alorair® Zeus 900 air mover are both excellent choices.


Dangers of flooding

Flood water is often dirty as it carries different substances from different places that it passes

inclusive of the dirt it carries from the source, thus if it happens to come in contact with drinking

water the water will become contaminated thus cause illness if consumed. Depending on the

pressure that floods come with, they may cause damage worth millions as it carries houses vehicles,

livestock, and even people. In the worst cases, floods will leave several people displaced, homeless,

and injured and will even cause death. It is best to always be prepared for these natural calamities at

all times especially when living in an area prone to them. Individuals should also always be on alert and

to always take heed in case such a calamity is said to be expected. It is always best to be safe than sorry.
