Levees And Seawalls During Hurricane Katrina

“There are natural hazards, but disasters are the result of human actions that put people and property in harm’s way” (Cigler 2007: 64). Throughout history New Orleans has been continuously altered by the presence of humans through the creation of levees and canals, the introduction of artificial irrigation systems, and through human induced processes that have ultimately accelerated the process of land degradation and erosion. While a natural hazard struck New Orleans in 2005, the disaster portion resulting from Hurricane Katrina was a result of human induced interactions throughout the history of New Orleans.

Hurricane Katrina, one of the most destructive hurricanes to whirl through the southern states of America in 2005, is probably one of the worst natural disasters of the United States in the 21st century. Damages from the storm were estimated at more than $100 billion . People living in the southern states fled north to reach safety from the storm after hearing about it being a category five hurricane on the news a few mornings before Katrina hit the shore. Authorities were doing what they were supposed to be doing, telling everyone to seek shelter, board up windows, head north and prepare for the storm. Everything in the beginning appeared to be just another

The failure to adequately prepare for the storm led to increased and more widespread devastation, which in many cases harmed those living in the affected areas. An independent analysis of the reason for such massive chaos was performed and determined that “Most of the damage was due to the failure of the levee system that surrounds the city to protect it from flooding” (Ubilla). Had these levees been properly built, and had there been more of them protecting the city of New Orleans, major flooding could have potentially been lessened. A simple feature of the levee structure which engineers neglected to include is the concrete

Katrina hit New Orleans, Louisiana on August 29th, 2005, but the failure of the government started before this day “by allowing building and growing in areas in low flood lands.” The government did not regulate these land areas that have always been at a threat for flooding and natural disaster, which was ignored by the government and public, and was in place, still a place for growing infrastructure. Failures included by the author of the national agencies include design limits that can lead to levees being overtopped by flood and hurricane events that are larger than they were designed for and design flaws and construction and maintenance shortcomings that lead to protective works being breached when they cannot stand up to the forces exerted by large flood and hurricane events. The author also points out the problems with the hundred-year flood event, which only has a one percent chance of happening every year. When the NFIP focuses on this possible catastrophe, it losses the

New Orleans was originally founded on high ground overlooking the Mississippi River, above sea level. Also surrounded by Lake Pontchartrain and Lake Borgne, New Orleans was susceptible to hurricanes that would come up the coast into the Gulf. Originally New Orleans was naturally protected by “coastal swamps that helped absorb the energy of storm surges before they reached dry land.” (Stillman 228) At this point Americans were more concerned with the floods that happened annually from the Mississippi River. In the early days, settlers built a mile long levee to block overflows from the mighty Mississippi while landowners constructed their own levees.

This case summarizes events preceding the Hurricane Katrina, which was one of the worst natural catastrophes in the modern history of the USA. It raises questions about the lack of reasonable prevention and preparation actions due to flimsy structure and management of the responsible organizations and persons, invalidity and inconsistence of their actions and incapability of making the decisions in a timely manner. As a result of the unstructured and incoherent activities, we could observe several ineffective and costly attempts to mitigate floods and hurricanes. In the beginning the local officials, U.S. Army Corps of Engineers and “White Houses past and present always seem penny-wise and pound-foolish” because of the chain of the wrong

It is difficult to even imaging how serious hurricanes can be. “Category 5 hurricanes are the strongest storms. Winds howl at more than 155mph.” (33) “They can be more than 300 miles from one side to another.” (6) In this nonfiction book, Wood begins with a description of Hurricane Katrina. He describes how it was one the worst storms in U.S. history. It devastated the Gulf coast with 140 mph winds ripping apart buildings and tearing down power lines. The main damage to New Orleans was due to big holes breaking through the levee and Lake Pontchartrain’s water flooding the city. Some areas were 20 feet deep, which left people stranded on their roofs for days before help arrived.

New Orleans as time has progressed has become more susceptible than most cities when it comes to the detrimental power of hurricane force and storm surges. There are two reasons for this. The first is that New Orleans has a very low elevation relative to the surrounding sea level, the second is the lack of Louisiana’s natural defense against storm surges; that is the coastal wetlands and its barrier islands.

Hurricane Katrina was a storm that hit the south; most of the storm struck New Orleans Louisiana. The twelfth anniversary is coming up on August 29, 2017. During the storm the mass amount of damage to the city included

In the year 2005, New Orleans was famously hit a major natural disaster that took lives and destroyed the homes and civilians. This wrath of Mother Nature became to be known as Hurricane Katrina, a category 5 hurricane with gusts peaking at 174/mph according to the Safir- Simpson wind scale (SSHS). With this Hurricane having its path directly on a city only being on average 1-2 feet below sea level, it created conditions for serious havoc (NOAA, 2012). The aftermath left a serious physical imprint on the city, which has the potential to never be removed. This imprint left by Hurricane Katrina caused extensive damage to 134,000 housing units, destroying multiple bridges along the Gulf Coast, as well as various buildings across the city, which led to harmful chemicals leaking into the water system, such as petroleum and natural gas. Finally, Hurricane Katrina also caused the main power grid to be disoriented for a number of weeks. As a result, the damage costs from the storm added up to be about $108 billion (2005 USD), which according to Eric Blake was the costliest storm ever to hit the United States (Blake et al. 2011). Hurricane Katrina perpetuated all of these tribulations, as it drastically altered the lives of the many inhabitants of New Orleans and they continue to face the repercussions of the storm in their day-to-day lives.

Hurricane Katrina resulted in massive loss of life and billions of dollars in property damage. There are many lessons worth learning from this event. Finger pointing started before the event was over. Most of the focus on Hurricane Katrina was on its impact on New Orleans; however, the storm ravaged a much wider area than that. This paper will briefly summarize the event, the impact on the city of New Orleans and the lessons learned to ensure preparedness today.

The city of New Orleans lies below sea level in a bowl bordered by levees which prevent the high waters of the Mississippi River from flooding the city. These levees were put to the test on August 29, 2005 when Hurricane Katrina hit, causing severe destruction along the Gulf coast. Three concrete floodwalls protecting the city of New Orleans fractured and burst under the weight of surging waters from the hurricane, killing hundreds and resulting in an estimated $100 to $150 billion worth of damage (Luegenbiehl, 2007). In the aftermath of the storm, society placed part of the blame on design flaws that compromised the safety of the levees and endangered the public. Under the Flood Control Act of 1965, Congress had mandated the US Army Corps of Engineers (USACE) to protect the city from a Category 3 storm, yet the floodwalls were unable to withstand the force of Hurricane Katrina, which was eventually classified as Category 3 (Grunwalk & Warrick, 2005). The Corps pointed towards a massive surge that exceeded the height of the floodwalls, but investigations by civil engineers and other experts pointed towards the inadequate design and construction by the Corps of Engineers as the cause of the failure (Englehardt et al., 2013). The Corps acted in a manner contradicting ethical engineering behavior by being less than forthcoming about deficiencies that were accumulating in the overall system. In order to prevent future disasters involving human life, the government should require

This is because in the event of a hurricane you could lose your house. The insurance companies will be more in the hole than the house owners because of their low premiums with a large return. The article also addresses how much more prepared we are now for a massive hurricane. One of the ways is we are upgrading our flood control systems, to prevent

Hurricane Katrina was one of the most devastating natural disasters on record in the United States (Skinner, 2006) In August of 2005, Hurricane Katrina made landfall along the Gulf Coast destroying buildings, homes and communities (Skinner, 2006). Storm surges and levee failures resulted in an estimated $108 billion in physical property damage, specifically in the areas of Louisiana, Mississippi and Alabama (Skinner, 2006). Furthermore, Katrina proved itself to be one of the deadliest disasters in U.S. history as it claimed the lives of more than 1,800 people (Skinner, 2006).

Numerous different aspects were altered due to the ruckus of Hurricane Katrina. The first major aspect was housing and location. Katrina nearly demolished 300,000 homes. The ascending sea level along the coast resulting from onshore winds is a storm surge. With a twenty-two foot storm surge in New Orleans and a twenty-seven foot storm surge in Mississippi, Hurricane Katrina averaged a shocking twelve foot storm surge. As a storm surge’s footage increases, the surge will continue to move inland farther and farther. Hurricane Katrina’s storm surge is documented as moving inland a total of twelve miles into the state of Mississippi (FAQS, 2013). Hurricane Katrina impacted a total of seven states. Five of these states were Georgia, Florida, Alabama, Mississippi, and Louisiana. Kentucky and Ohio were two more states affected but in a different way. Because of the tremendous amount of water, Kentucky and Ohio were victims of the Mississippi River flooding. Some states experienced more extreme destruction than others. Alabama, Mississippi, and Louisiana experienced Hurricane Katrina’s wrath firsthand. These three southern states were affected the worst by the massive storm (FAQS, 2013). Mississippi’s forest industry experienced a great amount of destruction losing 1.3 million acres of valuable forest land. The main cause of destruction in New Orleans was blamed on the failure of the levee system to stand its ground
