Flooding Damages and Proper Ways to Control It
A body of water covering land usually dry under normal circumstances is what defines a flood. Floods constitute regular natural calamities. Human development is always affected by flooding worldwide. Listed among the effects of flooding are they destroy premises, influence soil erosion and contaminate water for drinking. Overflowing lakes, rivers as well as seas are just but a few causes of floods across the world. Flooding is as historical as human life. Civilization in ancient times took place along waterways. This was because of the need for water by people.
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. Floods are responsible for depositing fertile soil in Bangladesh during the monsoon season although they are also destructive to humanity. However, they also kill thousands of people in addition to destroying property.
Floods always hit land next to rivers and water masses at yearly. Rivers carry in excess of their capacity during rainy seasons. Melting of snow in the mountains where most rivers have sources is another cause for floods. Thunderstorms result in flash floods as well. The capacity of rivers becomes ten more times their usual strength. Usually, those that flow slowly 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.
The rate at which rivers in Phoenix AZ erects develops floods is slow but results devastating. 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. Courtesy of the height of waves, floods affect land that several miles away from the coast. In the Indian Ocean for instance, a tsunami that was devastating resulted in more than a quarter a million deaths. Deaths were recorded in Thailand, Sri Lanka and Indonesia.
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 effect was felt in Fort Myers and Phoenix AZ. Responsible authorities whisked people away to avoid more deaths. Low-lying areas have a higher risk of flooding. These areas are common in the Netherlands. Similarly, life in Haiti came to a standstill as almost the entire country was wiped by floods.
Actions by human beings also cause flooding. Trees and other plants are helpful in absorbing excess water. Cutting down trees leaves the land bare for water to act on. Mudslides result from the same. Actions of excess water on dams causes cracks. In fact; total breakage is the final result. Safety and protection measures are nowadays taken to prevent the destructive nature of floods. Dams and dykes in the Netherlands control the water.
