The Cumberland and Cumberland River basin experienced a 36 hour rainfall that produced flooding in Nashville and its greater area (After Action Report, II). The 2010 two day storm was believed to be greater than a 100 year event. Storm activity began on May 1st and 2nd which created a large scale flash flood along the Cumberland and Lower Tennessee rivers, and within its tributaries. Historically the Cumberland River basin has received great amounts of precipitation and has experienced extreme rainfall before, making it prone to severe flooding (After Action Report, I). Some of the historic floods that have affected the Cumberland River are the December 1926, January 1927, January 1937 and March 1975 floods, which produced a maximum flood height in much of the river. Before the May 2010 flood, the Cumberland River reached a flood stage of 45.26 feet during the May 1987 flood which was a result of a series of flooding events that took place during an extensive amount of time (After Action Report, 4). The 2010 flood which affected much of Nashville acted more like a flash flood, which produced record breaking rainfall for much of the area. According to the Quantitative Precipitation Forecast (QPF) on April 30th rainfall totaled 7.8 inches across central Tennessee. The report also states that there was a widespread of rainfall equaling to 2 to 6 inch in total, over southeastern US stretching to Illinois, Indiana and Ohio. Rainfall for parts of western Tennessee and Kentucky totaled 3 to 4 inches with a high of 4.65 inches (After Action Report, III). As it is stated by the report areas around Nashville received more than 13 inches of rain in a span of 36 hours, which doubled the record set by the September 1979 flood event. At th...

... US stretching to Illinois, Indiana and Ohio. The flood had a property damage that exceeded $2 billion dollars and also a total of 37 people who died, despite the many warnings received. This epic event was considered as the 100 year flood that western and middle Tennessee had been expecting since the last widespread flood occurrence. The Cumberland River which is a major waterway that crosses through north-central Tennessee accumulated so much rain, that it resulted in a crest increase in Nashville at 51.86 feet, 12 feet above the flood stage. The heaviest rainfall occurred across Davison, Williamson, Dickson, Hickman, Benton, Perry and Humphrey’s counties, which translated into an average of 14 to 15 inches of rain, which are equivalent to 420 billion gallons of water in just two days. The 2010 Nashville epic flood event broke the record set for rainfall in 1979.
Case study: the flooding that occurred in Minden Hills in the spring of 2013, flooded the downtown core. The picturesque cottage town has the Gull River flowing through it. The river overflowed in April because of many reasons: a couple of days of rain, the third largest amount in over a century, but it also happened because the frost in the ground stopped the water from going into the Earth, the lakes and rivers being full from the spring thaw, and the rapid
A major flood on any river is both a long-term and a short-term event, particularly any river basin where human influence has exerted "control" over the ri...
Hydrosphere of the Mississippi River A Case Study of * River management * People interfering in the hydrosphere * A flood management scheme River Basin / Catchment area The source of the river is the eastern side of the Rocky Mountains and the Appalachian Mountains to the north. There are many hundreds of tributaries including the Red River, Missouri river and the river Ohio. The mountains form the river's watershed. From Minneapolis the river flows South-East into Iowa where it flows south as far as Davenport. At Davenport it is joined by more small tributaries.
Mississippi was also managed in New Orleans to limit flooding. This was done through levies that were at first naturally built by the river’s mud flows during floods. Later the levies were built higher and higher to keep the flooding Mississippi into the New Orleans area. But the levies were often ineffective in managing, or led to, more flooding. Kelman explains this when they write “With the development in the Mississippi Valley ongoing and artificial banks confining more runoff inside the channel, the river set new high-water marks” (Pg 702).
In a passage from his book, Rising Tide: The Great Mississippi Flood of 1927 and How It Changed America, author John M. Barry makes an attempt use different rhetorical techniques to transmit his purpose. While to most, the Mississippi River is only some brown water in the middle of the state of Mississippi, to author John M. Barry, the lower Mississippi is an extremely complex and turbulent river. John M. Barry builds his ethos, uses elevated diction, several forms of figurative language, and different styles of syntax and sentence structure to communicate his fascination with the Mississippi River to a possible audience of students, teachers, and scientists.
This bill provided jobs, electrical power, and flood control for the cities around the Tennessee Valley. The Tennessee Valley is a drainage basin for the Tennessee river in the southeastern United States. During the Great Depression this area suffered from flooding,,the ability to provide electricity, and lack of forest. The Tennessee Valley Authority Act pushed out to build dams on the river for electricity, to control the flooding, and much more. Because of the act, it brought more jobs to the Tennessee Valley and revived the Valley. Today the TVA is the largest public power company in

When someone thinks of the word “flooded,” they tend to think of something being completely covered with water and it is more of a devastation than relief. In One Foot in Eden, there is a company called Carolina Power and they are coming into Jocassee to flood the land. Rash presented the fact of Carolina Power coming into the land to flood it when he states “I’d farm this land until Carolina Power ran us all out and drowned these fields and creeks and the river itself (40). For more factual evidence, the flooding in the Ron Rash’s book was based on true events. “In 1963, Duke Power Company (a Duke Energy Company, or DEC) formed Carolina Land and Timber Company, which purchased an 83,400-acre tract of land in the Horsepasture area from Singer Corporation and private landowners. Duke Power Company (DPC) announced [the] construction of the Keowee Toxaway Project on January 2, 1965, and began development in 1967. The construction resulted in the formation of 18,400-acre Lake Keowee and 7,500-acre Lake Jocassee” (History of Lake Jocassee). Along with the flooding in the book, there was a Great Flood in the Bible that God did happen. In Genesis 7:4 NKJV, God said: “For after seven more days I will cause it to rain on the earth forty days and forty nights, and I will destroy from the face of the earth all living things that I have made (biblegateway.com).” As a comparison of the two events that took place, the
McCullough presents a meticulously researched, detailed account of the Johnstown Flood of May 31st 1889, which provides arguments for why the disaster was both “the work of man” and “a visitation of providence”. However, it is apparent that McCullough believes that man was more responsible than nature/god for the extent of the catastrophe. In McCullough’s opinion, the storm that caused the flood was no more than the inevitable stimulus of the disaster, whereas the deferred maintenance and poor repairs on the dam were the primary reason that Johnstown was devastated in 1889. McCullough exposes the failed duties of Benjamin Ruff and other members of the South Fork Fishing and Hunting Club, whilst simultaneously questioning the responsibility of the Johnstown folk who were concerned about the safety of the dam but complacently trusted the wealthy, powerful club members to fulfil their responsibilities. McCullough clearly explains the debate that took place immediately after the flood, on what or whom was to blame for the disaster, by explaining the views of the press, the townspeople and the lawsuits that were filed. McCullough’s view is evident from the sub-title of his book. By placing the word “natural” within quotation marks, McCullough immediately suggests that the flood was unusual to any other, and implies that mankind has displaced its blame onto nature.
By August 28, evacuations were underway across the region. That day, the National Weather Service predicted that after the storm hit, “most of the [Gulf Coast] area will be uninhabitable for weeks…perhaps longer.” New Orleans was at particular risk. Though about half the city actually lies above sea level, its average elevation is about six feet below sea level–and it is completely surrounded by water. Over the course of the 20th century, the Army Corps of Engineers had built a system of levees and seawalls to keep the city from flooding. The levees along the Mississippi River were strong and sturdy, but the ones built to hold back Lake Pontchartrain, Lake Borgne and the waterlogged swamps and marshes to the city’s east and west were much less reliable. Even before the storm, officials worried that those levees, jerry-built atop sandy, porous, erodible soil, might not withstand a massive storm surge. Neighborhoods that sat below sea level, many of which housed the city’s poorest and most vulnerable people, were at great risk of
About a week later a tornado razed a better part of North Houston. It brought rain. It brought hail. It upended cars; it flooded houses. And in its trail it left fallen branches and trees, and removed, in whole, one tiny tomato-onion-potato-and-green-bean garden located behind my garage.

One issue facing my locality is constant, yearly flooding that disrupts much of Glenville and the entire county. The Mayor of Glenville, Dennis Fitzpatrick, mentioned in an interview with me that “almost every year major flooding occurs,” and as someone who has lived near Glenville my entire life, I have also noticed the major issue of flooding as well. In Glenville, almost every ten years there is a major flood event that disrupts businesses and schools, while leaving much of the town with a mess to clean up afterwards. This is a pricey burden for a small town, and one that puts more and more local business at the risk of closing permanently. Once, my grandmother had
Humans currently use 80% of the former floodplains. Roads and railways cross the alluvial areas behind the protecting dykes; cities and villages have spread to the fertile river plains. This inundation of the floodplains has caused flooding in the lower reaches of the river during the period of snowmelts in spring. In 1995 heavy rainfall struck many parts of Europe, so heavy infact that some areas experienced it continuously from November 1994 to February 1995.
A Flood Hydrograph and the Factors That Affect its Form A flood hydrograph is a graph of two axis, 'discharge' and 'time'. Plotted on the graph is the amount of discharge over a period of time. By looking at a hydrograph, a lot of information and data can be gathered about the river, the precipitation, the surrounding area and vegetation etc. The gradient, height and length of a line can tell you a lot of this information. There are many different factors that can affect the appearance and shape of a hydrograph.
