Effects of Flood Damages
A body of water covering land usually dry under normal circumstances is what defines a flood. Common natural calamities include floods. They take back human development anytime they occur. Listed among the effects of flooding are they destroy premises, influence soil erosion and contaminate water for drinking. Floods result from many causes among them overflowing lakes, rivers as well as seas. Flooding is as old a human life. Civilization in ancient times took place along waterways. The reason was simple as human life needs water.
However, it is not always that floods remain destructive in nature. Nutrients deposited by floods every year around River Nile in Egypt by the river made the entire region fertile. This was before the floods along the said river were contained by the construction of Aswan High Dam. Despite their fatal nature, floods deposit fertile soil in Bangladesh during the monsoon season. It is besides the fact that so many lives are lost in the process.
Floods always hit land next to rivers and water masses at yearly. Rains result in more water for rivers to carry. When snow in mountains melts, it is another likely cause for flooding. Flash floods are caused by thunderstorms in many ways. In this case, small rivers swell fast forcing them to carry water tenfold their capacity. Slow moving rivers carry silt, sand and water. In the process, they put up their beds. Beds make the rivers occupy a higher level than the surrounding land. Rivers in Chicago are such examples.
Phoenix AZ Rivers build floods slowly but the result is more damaging. The effect goes to more land. Coastal rivers such as those in Fort Myers are also on the receiving end of floods. 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. Deaths were recorded in Thailand, Sri Lanka and Indonesia.
Identified causes of floods are Cyclones, hurricanes as well as tropical storms. Both Chicago and the Mississippi suffered hugely from Hurricane Katrina. Fort Myers and Phoenix AZ felt too. Residents of these areas were evacuated by government agencies and other humanitarian organizations to avoid further human fatalities. Low-lying areas and countries are in a permanent danger of flooding. The Netherlands, whose major part lies below sea level, is an example. Similarly, life in Haiti came to a standstill as almost the entire country was wiped by floods.
Actions by human beings also cause flooding. The role of trees and plants in consuming excess water is not debatable. Deforestation leaves rainwater to flow through barren land. These actions cause mudslides during rainy seasons. Excessive pressure on dams by water leads to cracks in the concrete wall. At times, they cause total breakage of the wall. Safety and protection measures are nowadays taken to prevent the destructive nature of floods. Water in Netherlands is controlled by erected dams and dykes.
