Flood Damages and How to Control the Situation

A body of water covering land usually dry under normal circumstances is what defines a flood. Floods constitute regular natural calamities. They take back human development anytime they occur. Identified negative effects include; 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. Civilization resulted from human being occupying riverbanks and bays. The reason was simple as human life needs water.

However, it is not always that floods remain destructive in nature. Fertility of the land around River Nile in Egypt owes its allegiance to floods by the same river. This was before the construction of the famous Aswan High Dam. Although human life suffers much, floods deposit fertile soil in Bangladesh during the monsoon season. 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. Rivers carry in excess of their capacity during rainy seasons. The other related cause is the melting of snow in the mountains where most rivers have sources. 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. Examples of such rivers are in Chicago.

Phoenix AZ Rivers build floods slowly but the result is more damaging. The effect goes to more land. Coastal lands in Fort Myers are not an exceptional to floods. Floor tsunamis that result from earthquakes on the ocean lead to more than 15-meter high waves. With this height, flooding spreads to miles away. More than 250, 000 people died as a result of the tsunami in the Indian Ocean. Affected countries included Thailand, Sri Lanka and Indonesia among others.

Experts also point at Cyclones, hurricanes as well as tropical storms as other causes of floods. Both Chicago and the Mississippi suffered hugely from Hurricane Katrina. 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. Haiti was compounded and almost crashed by floods.

What people do in many ways contributes to floods. The role of trees and plants in consuming excess water is not debatable. 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. Destructive floods are now being controlled through many ways. Dams and dykes in the Netherlands control the water.
