Effects of Flood Damages
The generally accepted definition of a flood is a body of water covering land usually dry under normal circumstances. Floods constitute regular natural calamities. They interfere with lives of millions of people across the globe. Listed among the effects of flooding are they destroy premises, influence soil erosion and contaminate water for drinking. Causes of floods are many including overflowing lakes, rivers as well as seas. Human life shares history with floods. Civilization in ancient times took place along waterways. This was because of the need for water by people.
It is essential to note that floods are not entirely destructive. Fertility of the land around River Nile in Egypt owes its allegiance to floods by the same river. The deposition took place way before Aswan high Dam was put up to control the floods. Despite their fatal nature, floods deposit fertile soil in Bangladesh during the monsoon season. However, they also kill thousands of people in addition to destroying property.
At least once in a year, land bordering rivers floods. Heavy rainfall in the sources of rivers makes them carry more water to the mouth. Melting of snow in the mountains where most rivers have sources is another cause for floods. Flash floods are caused by thunderstorms. The capacity of rivers becomes ten more times their usual strength. Slow moving rivers carry silt, sand and water. It results in them erecting beds. This result in them being higher than the surrounding land. Rivers in Chicago are such examples.
Damaging effects of floods by rivers in Phoenix AZ is a product of gradual development. The effect goes to more land. Floods do not spare even coastal lands found in areas such as Fort Myers. Waves from floor tsunamis raise up to a high of 15 meters. They then flood several miles on the land from the coastline. A tsunami in the Indian claimed more than 250,000 people. Thailand, Sri Lanka and Indonesia are some of the countries that felt the effects.
Experts also point at Cyclones, hurricanes as well as tropical storms as other causes of floods. The whole region of Mississippi Delta felt the strength of Hurricane Katrina as it did Chicago. The floods did not spare Fort Myers and Phoenix AZ. Participating agencies did well to evacuate people as damages and ravages would have been more. The dangers of flooding increase in low-lying regions. The Netherlands is one such country. Recently, floods almost wiped Haiti out of the world map.
Human beings also cause floods through their actions. Trees and other plants are helpful in absorbing excess water. Deforestation leaves rainwater to flow through barren land. Mudslides result from the same. Actions of excess water on dams causes cracks. At times, they cause total breakage of the wall. Destructive floods are now being controlled through many ways. Dams and dykes in the Netherlands control the water.
