Essay on The Cause of the Devastation of Hurricane Katrina

The historical event of Hurricane Katrina, a category three hurricane with winds ranging from 111-130 mph, in August 2005 revealed major structural failures in the levee systems of New Orleans. Though not all structural failures are as catastrophic, the breeched levees led to loss of life, homes, businesses, highways, and left a trail of destruction that is still being repaired today. The result of this failure led to lawsuits, conspiracy theories, and court cases. Hurricane Katrina had a major effect upon our country and those results are still rippling on today. Though a city once devastated, major improvements to the failed system have been made and leave the city feeling safe once again. When Hurricane Katrina hit New Orleans…show more content…
Between these three levees alone, the congressional inspection discovered more than fifty breeches in the structural design. Once the speculations of a faulty levee system were proven correct, the blame inevitably fell upon the designer’s shoulders; the federal company of the U.S. army corps of engineering. This organization admitted to have fallen short of the specifications required for the levee. Five main studies were completed to determine the cause of the levee failure, two of which derived from LSU and FEMA.
The studies found: that the levees did not follow design specifications, there were incomplete sections, surrounding soil gave way, substandard construction of levee segments, and warning signs were ignored.
Many comparable breeches along the levees were found throughout the city. Sections of the wall that were incomplete and cracked prior to the hurricane were the first to fall. Many junctions of the canals were poorly engineered and were too weak to handle any great amount of pressure. The safe load for the canals was designed to hold around fourteen feet of water flow. In reality, the canals were only built to safely hold seven feet of flow. In most places the water never capped the tops of the canals, they simply broke when halfway full. One of the main causes for this was that the steel sheet pilings were seven feet less deep than the designs called for. This allowed for the already

Causes & Effects of Hurricane Katrina
All hurricanes are formed in tropical waters, and many get their start in the Atlantic Ocean. These storms can only form in warm waters when the sea, wind and air pressure conditions are just right. Once they are active, hurricanes can be moved around by powerful gusts of wind known as steering winds. The winds help build the hurricanes up and give them more power, and when they are large enough they can cause massive rain fall, large waves that break well beyond the shoreline known as surge storms and a spiraling cyclone of wind and water that can be destructive and deadly.
Katrina was a massive hurricane that formed in the Atlantic in 2005, and at times reached Category 5 status. The storm was described as being among the worst natural disasters of all time. While at its peak, Katrina caused severe flooding and produced more than 1 inch of rain every hour, leaving some areas completely submerged under nearly 20 feet of water.
Some scientists claim that global warning is partially to blame for the power and endurance of hurricane Katrina. Hurricanes are formed in tropical waters, and need continued heat to exist, so the warming of the oceans is considered by many authorities to be a cause for more frequent and powerful hurricanes.
Effects of Katrina
Katrina was responsible for property damage and fatalities in Louisiana, Mississippi, Florida, Georgia and Alabama. During the time it was active, over 1 million people were evacuated from their homes to escape the fury of the storm. The estimated amount of damage that was created by Katrina was an astonishing 81 billion dollars.
Perhaps the best known area that was seriously affected by Katrina was New Orleans. Heavy winds mixed with ...
