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.
Mississippi has also been affected by the great floods of 1927. Furthermore, Hurricane Camille in 1969 and hurricane Katrina in 2005 caused major damages in Mississippi especially in the gulf coast region. All three of these events led major damage to property and businesses in Mississippi. The great flood of 1927 began with very heavy rains in the central basin of the Mississippi river in the summer of 1926. The flood affected Mississippi and several other states.
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 of Mexico is expected to be the largest on record (University of Michigan, 2011; NOAA, 2011).
Precipitation has increased 37 percent since 1958 (Jeff Spross). However a few major floods have been recorded dating back to 1913. In 1913 torrential rainfall hit Indiana and Ohio. The ground was greatly damaged from the flood causing difficult agricultural years for many years after the flood. Another flood hit a large portion of the Midwest region including the eastern Dakotas, Wisconsin, Kansas, and Indiana in 1993.
Memphis Tennessee floodings are awful events, but some have left their mark in history, and have impacted society making many people search for solutions. Historical flooding events have dated back beyond 1927, but Memphis’s first calamitous flood was in 1927, then in 2011, but between those dates there have been street floods that happen without interacting with the river. Many important aspects of everyday life are lost during floods such as lives, homes, and money. People have been searching for solutions to prevent floods, and ideas that are executed well could easily become an ideal panacea. Memphis is where I have been raised and experienced several floods, which gives me a much stronger feeling about the history, impacts, and techniques to stop floods.
An important source of sediment to Louisiana's delta wetlands was periodic flooding of the Mississippi River, which deposits new material on the flood plain. Massive levees built along the river bans now contain these floods and eliminate the supply of sediment to the wetlands. As a results, the natural compaction and subsidence of the delta are no longer balanced by the deposition of new sediments, and the local relative sea level is rising as much as 1cm per year. Human actions can also lead to the destruction of dune grasses and the disturbance of coastal landforms promotes inc... ... middle of paper ... ... 7000 containers. However, if this proposal is to go ahead, it will lead to the total loss of the foreshore mudflats and grazing marsh.
Colten (2005) maintain that human wrested New Orleans site from nature resulting in continual struggle with water and floods. New Orleans flooding risks originated from its location characteristics in proximity of Mississippi River. Since its foundation up to 1927, New Orleans water and flooding threats originated from Mississippi River but human activities had contained this by 1930s. Regrettably, this led to additional water problems. Accordingly, the critical changes to the New Orleans environment originating from the human development worsened the water problems in area caused by the floods.
Let’s look at how Louisiana came to its current demise and what is being done to rectify the situation. Historical Data As sea level rose and fell over Louisiana in previous centuries, the Mississippi River carried large loads of sediment to the Gulf Coastal area from the core of the North American continent and deposited it on the rim of the Gulf of Mexico. Prior to the twentieth century, 5 million acres of land were compliments of the large influxes of mud from the river’s mammoth basin, extending from Montana to New York State. Organic matter from highly productive marine waters has been deeply buried under the whole state and far offshore, turning into petroleum. During other dry periods, large beds of salt were laid down through evaporation.
Introduction On October 30th, 2004 a flash flood struck the Manoa Valley on the island of Oahu. The flood damaged more than 60 homes and caused more than one million dollars in damage to the University of Hawaii. Based on several events that have occurred Meteorological Causes & Concepts In order to understand what happened that day in Hawaii, we must first examine the common causes of flash floods and how they occur. According to DisasterCenter.com floods occur when there is prolonged rainfall, heavy, intense rainfall, or some kind of jam that overflows in a river or stream. These types of floods occur within a few days after the rainfall and can last as long as a week.
Louisiana is known for being an area prone to hurricanes, and millions of dollars of damage have been caused in this state almost every year. A major concern for a way to prevent future and major damage then started in the early 2000’s. The levees were designed by the U.S. Army Corps of Engineers and they had to decide how to build these levees to withstand hurricane forces. Although they were built for hurricane forces, it could not stand up to Katrina in 2005, when they broke and flooded the entire city. I am studying the levee break during Katrina because I want to find out why the engineers decided to design for smaller hurricane forces so my reader can better understand that the engineers may have underestimated the potential harm to public.
