Field Sketch Of Groyne Introduction ------------ I went to Sheringham on the 17th of July 2002 to carry out the fieldwork for my geography coursework. I went to Sheringham, which is situated, on the north Norfolk coast. The grid reference is 160436. [IMAGE] We went to Sheringham for various reasons and chose it over other places around the area. The main reason was because Sheringham has an ideal example of what the coastline directly behind the sea is like both protected and
Beach Survey In a group we did a beach survey of the protected beach and the unprotected beach. At each of the two locations we measured the angle of the beach and the depth of the sand. To start our beach survey we laid out measuring tape from the sea to the cliff (or 30 meters out) on the unprotected beach but on the protected beach the tape went from the sea wall to 30 meters out. We used survey poles - 3 meters apart - making sure they were vertical. At each survey pole we took a
the landforms of the coast. The purpose of a seawall is to protect areas of human habitation, conservation and leisure activities from the action of tides and waves. Seawalls may be constructed from a variety of materials, most commonly: reinforced concrete, boulders, steel, or gabions. Additional seawall construction materials may include: vinyl, wood, aluminium, fibreglass composite, and with large biodegrable sandbags made of jute and coir. A seawall works by reflecting incident wave energy back
In Roman times St. Mary's Church was built with Twin Towers as part of the building. Originally the church was 3kms away from the sea but as the cliff was eroded it eventually became next to the see. There was a danger the cliff under the Twin Towers and therefore the Twin Towers themselves would be destroyed by erosion. To stop this happening many coastal defences and different types of management have been erected. The initial try at coastal management was in 1809. Wooden and ragstone
Seawalls: Good or Bad? Walter Cavanaugh and Gary Grossman had a serious dilemma. Their entire households were literally falling away from them. Their houses on Indio Drive in the Sunset Palisades Planning Area in Pismo Beach rest atop a bluff that protrudes into the sea. The impact of the waves of the Pacific Ocean against the land was eating away at the bluf, breaking it down into gravel. In 2001, the two proprietors decided to do something to protect their property. On December eleventh
availability and various hydrodynamic reasons. The island also suffers from erosion due to major storms, like hurricanes, as well as other natural disasters. Much effort has been put in place to reduce the amount of erosion and/or migration, including a seawall and jetties. These efforts are not 100% effective and while the island will continue to transform; with human intervention, we hope to mitigate this change to a minimum. Barrier islands are seen mainly in coastal settings with three main characteristics
Collaroy before the development of human infrastructure: Before human intervention, the coast of Collaroy was a series of sand dunes. The beach carried out its natural process and was undisturbed by human activities and construction. The beach has always had extensive sand dunes behind them, however this did not create negative impacts because it was a natural occurrence and there was no infrastructure intruding onto the beach. This is evident in Source A (found on the next page) a photograph, displaying
Figure 3 Damage to waterfront property Source: tonkinntaylor The Seawall Hard engineering as a form of coastal management involves structures along the coastline, aiming to dissipate wave energy or trap sand to widen the beach. This form of coastal protection works towards protecting the land and the structural development behind it. Hard engineering is a more environment-based change. The Hawke's Bay Regional Council has erected a seawall, designed mainly to resist wave action and create a physical
animals such as fish and crustaceans. Some more advantages to this type of shorelines is enhancing water quality, as vegetation can filter the runoff, carbon sequestration, and use for recreation as it is safer for most people than climbing on a seawall or riprap revetment. Over the years, a natural shoreline will get stronger and more effective unlike built shorelines that stay the same or might even degrade over time. Something that can make natural shorelines very cost-effective is that they
The coast is defined as the place where the land and the sea meet. This includes the adjacent waters, as well as the shoreline and extends so far landward and seaward (Post & Lundin, 1996). The width of the coastal zone varies due to the seasonal changes and any adjustments, whether natural or manmade. While preventative measures must be put in place to mitigate these effects, procedures must also be put in place to ensure that the coastal zone can bounce back from the impact of these effects.

i) The two stakeholders that could become involved with the development near Greenhills Beach are the local council and the community. For the local council, they will most likely oppose the Greenhills development, as it is in their best interests to protect the beach from pollution and to keep it available for the public to use. The council could allow the development to occur, but with strict regulations and environmental laws in place. The community is a crucial stakeholder where the development
The average elevation of New Orleans is about six feet below sea level and is completely surrounded by water. As the 20th century progressed, the Army Corps of Engineers built a complex system of seawalls and levees to keep the city from flooding. Two significant event management failures of both the Galveston hurricane and Hurricane Katrina was how late mandatory evacuations were announced and the misjudgement of the how powerful each hurricane would
Galveston from future hurricanes. Galveston took plenty of steps to keep the city safe from future storms. Galveston was raised 17 feet above low tide. They also built a seawall, the seawall extends over 10 miles along Galveston's seafront, protecting life and property against hurricanes and tropical storms. The need for such a seawall became apparent when on September 8, 1900, a hurricane struck Galveston island resulting in the greatest natural disasters in the U.S. history. Having an action plan is
less natural and more man-made ways of preserving the coast. One of these alternatives is seawalls. Seawalls are structures that are placed on the coast to slow shoreline erosion. Seawalls are meant to hold the soil in place and to prevent it from sliding, while also offering protection from wave action. They serve as coastal flood defences in addition to their primary purpose of reducing erosion. Seawalls can be built in several materials and can take either a vertical or sloping shape, shape varies
immense amount of debris that needed to be cleaned up. The people of Galveston had to look for bodies and people who were buried alive. Galveston had to rebuild everything and start all over. The people living there came up with an idea to build a seawall that would protect Galveston from large waves created by another hurricane. They then also raised the city by as much as 17 feet in some areas. The Galveston Hurricane of 1900 was an unexpected and drastic natural disaster that
Issac’s Storm is a non-fiction narrative written about a man named, Issac Monroe Cline, who lived through one of the most catastrophic hurricanes the world has seen. This hurricane took place on Galveston Island, on the Texas coastline on Friday, September 7, 1990. With one hundred and forty five mile per hour winds when making connection with Galveston quite a tremendous impact was made on the surrounding community, a community that was booming with life and considered one of the biggest cities
Hard construction • Sea Walls Pros – Provides an outstanding defence where wave energy is high reassures the public and long life span. Cons- Very expensive, can affect people from accessing the beach, recurred sea walls can increase the erosion of beach material (Internetgeography). • Groynes Pros- Cheap retain wide sandy beaches and do not affect access to the beach. Cons- Beaches to the south of the defences are deprived of beach material due to their affect on long shore drift (Internetgeography)
effected by sea level rise, storms and currents and many techniques have been used in the past to combat erosion issues that threaten to wash away beaches and homes in the process. Erosion preventative structures used in the past, such as jetties and seawalls, have proven to be even more damaging to beach erosion but Beach Front Management policies and local and state government agencies are working hard to reverse the effects and incorporate new ways to fight erosion. Today new policies are in effect
Soft, where the sign is positive in the unrestricted models incorporating objective measures of flood risks to private homes. Mean estimates of marginal utility for all attributes are statistically significant across all models except for Soft and Seawalls. Mean marginal utility obtained from wetlands protection is statistically significant only in the unrestricted model adopting zone as a measure of risk to private property. Models results suggest the presence of significant heterogeneity around the
