n 1973, the Mississippi River was out of its banks for more than 2 mo from April to June. The thickness and the texture of overbank sediments were determined for a number of depositional environments on the Mississippi River flood plain in Louisiana. Average sediment thickness ranged from 53 cm along the natural levee to 1.1 cm in the back-swamp. The texture of deposits varied from natural levee sediments with 68 percent sand to backswamp sediments with 97 percent silt and clay. The amount of lateral erosion of bordering Pleistocene bluffs increased 271 percent over the previous 9 yr of record because of the flood. Using the rate of backswamp deposition during the 1973 flood, it is suggested that backswamp deposits in this area required 10,000
Flooding of the settlement was problematic. By 1812, the settlers had built miles of levees on the banks of the river. For the next two hundred years, the surrounding wetlands were drained to eliminate swamps filled with yellow fever carrying mosquitoes and to encourage economic development. Draining water from peaty soils encouraged subsidence. The land which was just inches above sea level to begin with steadily sank. In combat of this, higher and stronger levees were built, tightening the straight jacket already placed upon the Mississippi River. The massive flooding of 1928 brought further flood control systems implemented by the Army Corps of Engineers with Congressional blessing. By the 1950’s, dramatic rates of land loss in Louisiana’s coastal zone stretched across 300 miles from Texas to Mississippi and inland 50 miles. (Tibbetts)
During our week in New Orleans, we will have excellent opportunities to learn about different cultures, the effects of natural disasters, and reasons as to why New Orleans is facing poverty and economic distress through our volunteer work with Project Homecoming, 1 in 5 homes in New Orleans is still blighted, 10 years after Katrina. New Orleans still has a high rate of blighted (abandoned) homes. We will be helping to rebuild homes, but we will also be helping to improve the surrounding community spaces such as there local gardens.
The characteristic warming climate of the Late Pleistocene and Early Holocene resulted in rising sea levels which contributed to the formation of the various deltas in the New Orleans area (Dunbar, Britsch, 2008). The natural formation of these deltas produced coastal wetlands that represent 30% of coastal wetlands currently in the United States (Cigler, 2007). In addition to these wetlands, the Mississippi River was surrounded by substantial forest growth (Pabis, 1998).
On August 29th, 2005 Hurricane Katrina caused catastrophic damage and flooding in Mississippi, Louisiana, New Orleans and areas in between. It destructed the lives and homes of thousands of people, with a total of 1,883 fatalities (Hurricane Katrina Statistics Fast Facts, 2015). Hurricane Katrina left many homeless and hospitals unprepared for the challenges posed to the healthcare system as a whole. Some of these challenges included gaining access to healthcare facilities, providing expedited care to those most in need, and preventing spread of disease that commonly occurs during natural disasters. Many facilities did not evacuate in time and many were left stranded in flooded waters as patients conditions worsened and access to essential medications and treatments became limited.
In the history of the United States of America, Hurricane Katrina was known as one of the worst hurricanes in the world. The hurricane was a combination of tropical waters and gushing winds. It was the vicious hurricane that caused severe damage to the citizens of the United States of America. The amazing city known for its southern style, Cajun cuisines, jazz music and its celebration of Mardi Gras will never be the same. New Orleans, Louisiana was changed forever in August 2005 when this category five hurricane left the city devastated. The catastrophic storm tore through the city of New Orleans and surrounding areas destroying everything in its path and killing hundreds of people.
The Mississippi River is highly regarded as the most important river in Louisiana. One of the lesser known rivers is just as phenomenal, however. The Atchafalaya River (pronounced At-cha-fa-lie-uh), which is adjacent to the Louisianan southern half of the Mississippi River, is so much of a phenomena that the United States Army Corps has been put in charge of controlling the river!
The Great Mississippi Flood of 1927 was one of the most destructive in the history of the United States, proving that the levee only policy was a failure and the limits of human control over the river. The beginning of the flood, from the initial crevasse, poured out “468,000 second-feet onto the Delta that triple the volume of a flooding Colorado, more than double a flooding Niagara Falls and the entire upper Mississippi ever carried” (pg 203). The flood of 1927 “shifted perceptions of the role and responsibility of the federal government… shattered the myth of a quasi-feudal bond between Delta blacks and the southern aristocracy...accelerated the great migration of blacks north. And it altered both southern and national politics....”
Would you believe me if I told you that it was just as effortless to swim in syrup as swimming in water? Well, it’s true! I realize it seems insane, doesn’t it? Throughout this essay, I am going to talk about the history of molasses (syrup), The Great Molasses Flood of 1919, and how we know swimming in syrup is much like swimming in a pool of water.
Everything in its path is a book that describes the wreckage and aftermath of one of the most server floods to strike West Virginia. The flood struck Buffalo creek a small narrow town in the hollow of the Appalachians Mountains in the winter of 1972. Debris from hundreds of mine operations spills down the slope like ashes. Buffalo creek is one of those mountains hollow that some seventeen miles in length. Around five thousands residents lived along this hollow this small strip of land in 1972 all of whom had houses and lives were washed away by the horrific flood that stuck Buffalo creek. The town of Buffalo creek depends on the mines for their source of income and lively hood. When the flood struck all of the
During the Civil War the Mississippi River was not only vital for military purposes, but also civilian life. The Mississippi River was an easy way to move troops, supplies, and equipment. In the civilian world it allowed farmers to trade crops and was vital to the economy in both the north and south. In fact President Lincoln feared that northern farmers would side with the south in order ensure movement of crops and resources to sustain life for their families (Gabel, 2013). However, Midwestern states understood the critical important to winning Vicksburg and Midwestern states like Illinois provides 36,000 troops in support of the campaign for the Mississippi River (Gabel, 2013). Access to the Mississippi was not always easy due to the surrounding
The Ellicott City flood was destructive because it was on a high gradient stream. The high gradient stream made it flood faster, and had low stream discharge. Discharge is cross section of stream channel. It was also capable of moving large particles, which is an example of deposition and erosion. In the experiment, the ‘Main Street Ellicott City’ stream was more affected than the Meandering Stream. The Main Street Ellicott City stream was flooded faster, and more houses and cars were destroyed compared to the Meandering
The Mississippi River influences the states of Louisiana in numerous ways. The river can be both beneficial and harmful to the state. It may help with industries, but at the same time it may be harming by taking away from Louisiana’s coastline. While erosion is widely considered to be a destructive occurrence, it does have some necessary features. For example, erosion provides many nutrients for animals living in the water, and it creates new deltas that many animals live in. Since the beginning of Louisiana, the Mississippi River has been a crucial factor in the creation and the development of Louisiana’s economy. It has helped with things like trade and the growth of crops. The Mississippi is also significant in the way Louisiana is shaped
The Johnstown flood, of May 31st 1889, is a devastating part of American history that forever changed the lives of thousands of people. Before the destructive flood more than 30,000 people lived in Johnstown and surrounding towns. The main industries of the time were the Pennsylvania Railroad and Cambria Iron Works, who also supplied houses that were often times built just at the edge of the Conemaugh River, which ran through Johnstown.
This spring, record breaking floodwaters along the Mississippi River caused massive damage in nine states, totaling over $25 billion dollars in damage (Watts, 2011). In most areas the floodwaters have receded, however there is concern that even a little rain could cause more flooding due to the already saturated land. As cities and towns are beginning the restoration process, one thing caused by the flooding waters cannot be restored. Pollutants’ such as nitrogen from fertilizer, due to this area being primarily composed of farming land, is making its way toward the Gulf of Mexico. Every year pollutants traveling in the Mississippi River enter the Gulf and contribute to the Coastal Dead Zone; however, this year the Dead Zone in the Gulf
Information that was used to develop my conclusions were relative to the history of Clearwater River such as the average normal discharge of 40,000cfs, the fact that the river can accommodate 55,000cfs before flooding will occur, and that with every increase of 2600cfs the river rises one foot. For example, this information helped to determine that four of the thirteen noted Peak Flood Discharges listed on the worksheet were not at flood stage as the river is able to accommodate discharges less than 55,000cfs. However, nine of the thirteen Peak Flood Discharges listed on the worksheet were at flood stage or drastically above; with the maximum rise of 17.77 feet above and a discharge rate of 101,200cfs. The average discharge rate of the top three noted floods per information on the Stream Gauge Data of Peak Flow Discharges is 93,613cfs, which is resourceful later in determining the extrapolated 75-year flood.
