Flooding Damages and Proper Ways to Control It

Professionals and laymen agree that a flood is a body of water covering land dry under normal circumstances. Common natural calamities include floods. They take back human development anytime they occur. Among other effects, they destroy premises, influence soil erosion and contaminate water for drinking. Causes of floods are many including overflowing lakes, rivers as well as seas. Flooding is as historical as human life. Notably, human beings started by settling along rivers and slowly began to civilize. Water is life as such; man was forced to settle along riverbanks.

However, it is not always that floods remain destructive in nature. The land around river Nile in Egypt for instance, became fertile due to the nutrients deposited by floods every year This was before the construction of the famous Aswan High Dam. Floods are responsible for depositing fertile soil in Bangladesh during the monsoon season although they are also destructive to humanity. This is despite the fact that the floods kill so many people.

Plain land next to rivers will always flood at least once every year. Rains result in more water for rivers to carry. Melting of snow in the mountains where most rivers have sources is another cause for floods. Flash floods are caused by thunderstorms in many ways. The capacity of rivers becomes ten more times their usual strength. Slow moving rivers carry silt, sand and water. They erect beds in the process. Beds raise rivers above their normal level even in comparison to the land that hosts them. You find such rivers in Chicago.

Phoenix AZ Rivers build floods slowly but the result is more damaging. More land stands affected. Coastal rivers such as those in Fort Myers are also on the receiving end of floods. Floor tsunamis that result from earthquakes on the ocean lead to more than 15-meter high waves. They then flood several miles on the land from the coastline. More than 250, 000 people died as a result of the tsunami in the Indian Ocean. 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. Just like in Chicago, Hurricane Katrina produced massive flooding in the entire Mississippi Delta. The floods did not spare Fort Myers and Phoenix AZ. Residents of these areas were evacuated by government agencies and other humanitarian organizations to avoid further human fatalities. Low-lying areas have a higher risk of flooding. The Netherlands is one such country. Similarly, life in Haiti came to a standstill as almost the entire country was wiped by floods.

Human beings also cause floods through their actions. No one disputes the role of trees and plants in protecting the world from the effects of excessive water. Cutting down trees leaves the land bare for water to act on. Mudslides result from the same. Dangerous cracks on dams by excess water are evident. In fact; total breakage is the final result. Many methods are developed o take care of the effects of floods. Dams and dykes in the Netherlands control the water.
