Understanding Flood Zones

flood zonesFloods are a common phenomenon in the natural world. The word is derived from the Old English word, “flod” which is a term that is commonplace to Teutonic languages. Some obvious comparisons are the German term which is “flut” and the Dutch “vloed”.

These are also seen in the root words of float and flow. The term “flood” is universal as it has happened in most places where people inhabit the earth. One of the causes of floods is the overflow of dikes as well as the melting of snow in some areas. This is also evident when bodies of water exceed their capacity to hold water. It is when these so-called reservoirs are unable to hold any more water.

It is also possible that floods also come from the sea. These types of flood may cause overfow or overtopping of flood-defenses such as dikes or the flattening of dunes. If ever the flood is strong enough, the land that may be behind the coastal defense may become inundated and may experience unnecessary damage. One of the reasons for a flood that may come from the sea is a heavy storm surge, a high tide, a tsunami or probably a combination thereof.

There are a considerable number of urban communities that are located near the coast of a major typhoon or hurricane belt. This is very common around the world and it is even much more common in the United States as some of its states are near bodies of water such as seas. It is possible that different flatlands may be overwhelmed with water when floodwaters come running over them and it will likely result in the destruction of the soil in those parts.

Although the idea of floods helping out with the farming cultures of the ancient Egyptians who inhabited areas near the Nile, Tigris and Euphrates rivers, it is now considered to be a bane of crops if the flood is not tempered enough. It should be remembered that for it to avoid becoming a natural disaster, it should be controlled.

One of the worst floods that has occurred is during the 1999 Queensland floods which essentially put the south-eastern parts of this area underwater. The area of Queensland was affected as it was plunged under water because of the overflow of the river banks during 1999. Because the soil and the vegetation were not able to absorb all of the water that was present in the area, it ran off the land in several quantities that were not carried in channels or natural ponds. It simply covered the land as a deluge of water.

It is important to consider several factors whenever one would be assessing if an area is more likely to be flooded in the future when bodies or reservoirs of water overflow. It would be very advantageous if people would consider future scenarios which would think of crisis-solving solutions if ever the threat of those types of natural disasters will strike.
