The Reasons for Aldeburgh Being Protected Differently than Dunwich
In this question, I will be looking at how Aldeburgh is protected more
than Dunwich, and the reasons why. I will concentrate more on the
reasons, and to answer this, I will look at the location, long shore
drift, and nearby places.
Types of Coastal Protection
Dunwich is only 9 miles north of Aldeburgh, but the methods of coastal
protection in these two places are very different. In Dunwich there is
a small amount of 'soft' protection. This means that natural methods
are used. We saw that there was vegetation, which had been planted on
the sand dunes near Dunwich Heath. There is also fencing around the
dunes to stop them being eroded through people walking on them.
Coastal Protection At Aldeburgh
Text Box: Fig 4.1Text Box: In Aldeburgh however, the types of
protection involve 'hard' protection. These are man-made objects. At
Aldeburgh, three hard protection methods have been employed, and one
soft method. There is: a curved sea wall groynes, rip-rap, and, beach
replenishment (fig 4.1).
Reasons For Different Protection.
Dunwich is a small coastal village on the Suffolk coast. There are
only 120 people living in Dunwich, consisting mainly of retired people
but with a few fishermen and forestry workers. With this in mind,
there is no real need to protect it from the sea. Although Dunwich was
once a major port, almost all of the historic remains have already
fallen into the sea.
Another reason for not protecting Dunwich is because the material that
is eroded from those cliffs is carried south by long shore drift and
helps to prevent erosion further down the coast. This is particularly
important with the presence of the Sizewell nuclear power plants 5
miles south of Dunwich. If hard protection were used at Dunwich, then
this would cause the cliffs at Sizewell to erode much quicker and
possibly cause a risk to the nuclear power plants and the town.

The sea wall protected the low-lying farmland and in addition to this the railway that links Ramsgate and London. A smaller recurved concrete sea wall was built west of the Towers to avert flooding at Reculver. Additional wooden groynes were sited on the beaches to delay longshore drift and maintain the shingle beaches, which itself is a defence. In the 1960s the houses at Bishopstone Glen were in danger of being destroyed because the soft clay and sandstone cliffs underneath them were so unstable. As a result another sea wall was built, this time underne... ...

There are many different types of coasts that exist throughout the United States. The south shore of Long Island has a unique types of coast known as a barrier beach. Barrier beaches are long narrow land forms that are composed of sand and other lose sediments. These sediments are brought together by the actions of waves, currents and storm surges. Barrier beaches are subject to constant changes by the same forces. Sand is constantly eroded in one area an deposited in another. Barrier coasts are important for a number of reasons; they protect the mainland of Long Island from the open ocean and flooding during storms, for recreational use and the unique ecosystems which exist on barrier beaches.
The Newburgh Conspiracy of 1782 was the closest an American army has ever come to a revolt or coup d’état (Kohn, 17). Due to the failed attempt to ratify the Impost of 1781, Alexander Hamilton, one of the most involved conspirators in Congress to partake in the conspiracy, along with other nationalist conspirators in Congress, attempted to use the threat of the conspiracy as a weapon to pressure Congress into accepting an amendment to the Articles of Confederation. This amendment would allow the national government the power to tax imports, which would also result in a stronger national government; the Impost of 1781 would have given the government the ability to lay a 5% duty on imports. Alexander Hamilton tried to encourage General George Washington to help pressure Congress as well, but Washington remained true to his position as general of the American Army.
Authorities at LSU's Hurricane Center and Water Resources Research Institute, and US Army Corps of Engineers lead a discussion of how Louisiana's coastal region is doomed to storm surges. A case in point is the deterioration of the Mississippi Delta, a triangular-shaped deposition of sediment, which works to mitigate flooding and damage caused by storm surges. In fact, every four miles of the delta could knock down a storm surge by one foot. Unfortunately, some areas of the delta like Port Fouchon are losing 40 to 50 feet of land per year. By 2090, experts at LSU have postulated that the delta will be gone - vulnerably leaving New Orleans on the sea. Aside from the delta, barrier islands and marshes are the only other two natural entities which could mitigate a storm surge. The barrier islands' black mangrove trees and the marshes' tall grasses interfere with incoming gulf currents. However, just like the Mississippi Delta, these natural entities are also eroding (Fischetti, 2001).
Today, with our understanding of how fragile the coastal areas are, there are many study and restoration projects underway. Since the implementation of the Coastal Wetlands Planning, Protection, and Restoration Act (CWPPRA) in 1990, there have been 151 coastal restorat...

The country of the Netherlands is a place of proud and prospering people with a rich Dutch culture and beautiful cities. Holland is constantly overflowing with innovative ideas and wondrous breakthroughs in agriculture, but for many years the Netherlands has faced a growing issue that is threatening the entire coast and mainland of their country. Global warming has contributed to a consistent increase of rising sea levels. Due to the issue that a majority of the mainland in Holland is well below sea level, the Dutch government has implemented necessary plans to revise the existing costal security program to protect the country from wide scale flooding and to ensure the security of the major cities and historic sites found throughout Holland.
Siege of Rochester in 1215 The siege of Rochester was a significant moment in the medieval period. In this essay I explore the decisions and policies by John that led up to one of the most dramatic periods in early medieval history and earned him the reputation of a bad, unlucky and cruel King. John became King in 1199, he owned nearly as much land in France than he did in England. But unfortunately for John he lost lots of this French territory, including Normandy. Richard the Lion heart was the main reason for this loss.
Glacial till is also common in the low-lying areas to the south and west of Greater Manchester. Following frequent changes in climate in the Quaternary period, glaciers have advanced and retreated leaving a layer of glacial deposits in their wake (Natural England). These deposits were transported downstream via meltwater rivers to lowland areas, making them fertile and very useful for pastoral farming. As such, lowland areas have become popula...
. Cape Hatteras Lighthouse is the 208-foot tall landmark was just hauled more than a quarter-mile back from its former perch, where it was threatened by the encroaching sea. Coastal erosion chewed away about 1,300 feet of beach, bringing the waves to within 150 feet of the 4,800-ton sentinel. When the light was erected in 1870, it stood about 1,500 feet back from the waves. The lighthouse, on the Outer Banks, North Carolina's long barrier beach, was built to warn ships from waters called "the graveyard of the Atlantic." Ironically, the move should serve as a warning about the growing problem of coastal erosion. Erosion is not just plaguing the Outer Banks. Coastal residents up and down the United States are worrying about undermined cliffs, disappearing beaches, and the occasional dwelling diving into the briny. Beaches are constantly moving, building up here and eroding there, in response to waves, winds, storms and relative sea level rise. Yet when commoners like you and me, and celebs like Steven Spielberg, build along the beach in places like Southampton, N. Y., we don't always consider erosion. After all, real-estate transactions are seldom closed during hurricanes or northeasters, which cause the most dramatic damage to beaches. Yet Southampton, like all the barrier beaches that protect land from the sea, is vulnerable to obliteration by the very factor that makes it so glamorous: the sea. And the problem is increasing because the sea is rising after centuries of relatively slow rise, and scientists anticipate that the rate of rise will continue to increase in the next century. Land, in many places, is also slowly sinking. The result is a loss of sand that places the occasional beachside home inconveniently near -- or in -- the water. Still, erosion cuts in two directions. Without the process of erosion, we would not have the beaches, dunes, barrier beaches, and the highly productive bays and estuaries that owe their very existence to the presence of barrier beaches. Erosion of glacial landforms provides most of the beach sand in Massachusetts. A popular destination The beach-erosion problem has many causes. Among them are: · The ubiquitous desire to live near the sea. · A historically rapid ri...
The question that I will be answering for my coursework is which is best at protecting the Northumberland coastline – groynes or beach nourishment. I will be going to Blyth beach also I will be visiting Newbiggen beach I am investigating the Northumberland coastline as part of my geography coursework also because I live in the UK and I want to see how safe the people of the UK are with the safety of the coastline and its defences against coastal erosion. We will be visiting the Northumberland coastline on Thursday the 15th of May 2014.
HOW LIKELY IS IT THAT THESE CONSERVATION ATTEMPTS WILL PROLONG THE LIVES OF OUR COASTAL WELANDS?
The oceans need to be protected because it is where life began and if not taken care of, life as we know it will end. When dangerous substances go into the ocean, ecosystems are suffer and become endangered along with lives of people and of marine life. Surfrider Foundation recognizes the importance of protecting and preserving the quality and biodiversity of the world's coasts because they are truly irreplaceable. There is also historical evidence of ocean pollution being present in the past, but the problem still lingers today. Heal the Bay discovered that,“Did you know there is a DDT and PCB hot spot off the coast of Palos Verdes? This superfund site (which indicates it's one of the most polluted places in the United States), is left over from a 1930's era chemical plant. Because DDT takes so long to break down in the marine environment, it persists to this day, contaminating certain species of fish. There are also highly polluted sediments in the Long Beach area, a sign of the heavy shipping in the port. Heal the Bay works on developing effective capping and removal plans to keep those toxins from spreading” (Heal the Bay). DDT is still highly concentrated in the South Bay area and still contaminating different species of fish. Even after more than 80 years DDT, a toxic insecticide, is still very concentrated and during upwellings, DDT particles come back up and continue to harm marine life. If humans are careless about what is thrown on the floor or sprayed on lawns, it can lead to disastrous affects when it comes to the condition of the ocean's ecosystems, and can endanger life itself leading to a problem that only we can mend.
