Coastal Management at Selsey
1. Introduction.
For this Coursework I will be studying the coastal management of East
Beach, Selsey, and also at Medmerry. The main issue that I will study
is 'How should the coastline be managed at East Beach, Selsey and at
Medmerry, near West Beach, Selsey.'
The methods that I used to collect information was varied, here is
what I did in my group:
First of all I measured the beach length, by using a measuring tape. I
measured the beach from the sea's edge to the top of the beach. Then,
I found out the angle of the slope of the beach, by making a
clinometer reading. To do this one person stood at the sea's edge and
the other stood at the top of the beach. Whilst holding the clinometer
at arm's length, we adjusted the clinometer so that the top was in
line with the other person's eye. You then pull the trigger and record
the angle given, then they swapped positions and repeated this
process. We then made Pantometer readings, which are readings of the
angle of the beach at every metre on the measuring tape. The measuring
tape that has measured the length of the beach, is then used so that
at every 1 metre along the tape the Pantometer is held straight and
from the protractor on the side, the angle can be read.

The wave length was then recorded so that we could see whether the
waves were constructive or destructive. Firstly we noted how many
waves passed a point on the beach, for 5 minutes. This number was then
divided by 5 to get the number that passed per minute. To see whether
there is Longshore Drift, we threw dog biscuits into the sea and
watched their movement. If it moves either left or right, it shows
LSD, but if it just moved in and out then there is no LSD. We carried
out this process 4 times, so that we were completely assured of
whether there is LSD.
Investigating the Geographical Processes that are Affecting the Physical and Built Coastal Environment There are three geographical processes that are affecting the physical and built coastal environment, they are; erosion, deposition, and transportation. Erosion is the group of natural processes, including weathering, dissolution, abrasion, corrosion, and transportation, by which material is worn away from the earth’s surface, this is mainly caused by wind, running water, and waves breaking on the coast. Deposition is the depositing something or the laying down of matter by a natural process. Transportation is when sand is moved along the coast by long shore drift. At North Cronulla beach erosion is evident.
This shows that it is eroded at one end more which is a sign of long
Birling Gap has quite a lot of history to it, a long long time ago it
Case Study of Hastings Coastal Management Hastings is a town on the south coast of England approximately 60 miles south of London (see map below). In recent years, the coastline at Hastings has had to face many large scale problems, including the 10 km stretch from Hastings eastwards to the small town of Fairlight. With the coastline at constant exposure to the English Channel, there are many coastal processes which take place along the stretch of beach and cliff.

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.

Semaphore is a classic Adelaide beach supporting many facilities. However, this would not be the case if coastal management was not put into progress. Coastal management is a way of supporting the world’s coasts, by using many techniques from construction of structures in which prevents wave energy from reaching the shore to planned strategies. Factors of this includes; rising sea levels, erosion, long and short term drift, sand movement and marine biology. The importance of coastal management is quite significant as it will help to prevent coastal erosion. In addition to this, without coastal management the world will be affect economically, environmentally as well as socially. Without the strategies involving the management of the coast,
Introduction The Chesapeake Bay is a large estuary located on the east coast of the United States. The bay is over 200 miles long and goes through Delaware, Maryland, New York, Pennsylvania, Virginia and West Virginia. The bay has much to offer the locals. Many locals have made a career out of harvesting the bay's sea food.
Most of this region’s history meshes with the history of the Delmarva Peninsula. Originally, when the English colonies were established, it was and the original focal point at the time, Chesapeake Bay, were part of the Virginia colony. However, the term Eastern Shore became a more common term to use because of everything was to the east of the peninsula.
Chesapeake Bay is known to be an extremely complex living system, and has been greatly disturbed over the past years. But there's been a problem around this watershed the past couple of years. The health of the Bay has been on a downward roll, and something is needed to be done in order to halt it. There have been multiple different attempts to try and reverse the damage that has been done. But, what has made the Bay get to this point; why is it important to restore; and what can be done to fix the health of Chesapeake Bay?
The Chesapeake bay is a home to millions of people and animals. The Chesapeake Bay holds more than 15 trillion gallons of water,also supports 348 species of finfish and 173 species of shellfish, and produces more than 500 million pounds of seafood harvest each year.The Chesapeake Bay watershed spans more than 64,000 square miles.Watersheds are sometimes called “basins” or “drainage basins,home to over 17 million people.The Chesapeake Bay is 165759.24 in square km’. The Chesapeake Bay watershed 2000 years ago was much more healthier than it is now. They had maple, oak,hickory, and beech, and evergreens, hemlock, spruce, and fir plants.The Chesapeake Bay also had many different types of animals.The Bay's waters are dominated by oysters, clams
Lysergic acid diethylamide, abbreviated LSD, is one of the most powerful substances in the world. Named LSD-25, as it was the 25th compound deriving from lysergic acid systematically developed by its chemist inventor, was first synthesized in 1938 and discovered to be psychoactive in 1943. It would reach peak popularity as a street drug in the 60’s and by 1968 it became illegal to possess. Hallucinogens produce quite a complex experience that affects the physical sense, the mind, and alter the mood. These experiences, often described as psychedelic, have been experienced as spiritual journeys and used as a form of medical treatment since ancient cultures first discovered their potential. The enormous spiritual and cultural importance has protected the substance Peyote (Mescaline) for exclusively the Native American Church in the USA (Robins, 1996). But no other substance has the same protection though have held heavy cultural and spiritual importance. LSD is one of those substances, it is a semi-synthetic substance, classified as a Schedule 1 controlled substance, and ramifications for possession are similar to those of highly addicting and dangerous substances like Heroin. This classification has drawn controversy, but there are two sides to every tale, this is a substance of remarkable potential for both euphoria and hell. It is safe to say LSD creates unpredictable experiences, and much remains unknown about this heavily criminalized substance.
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.
An Analysis of Dover Beach Dover Beach intrigued me as soon as I read the title. I have a great love of beaches, so I feel a connection with the speaker as he or she stands on the cliffs of Dover, looking out at the sea and reflecting on life. Arnold successfully captures the mystical beauty of the ocean as it echoes human existence and the struggles of life. The moods of the speaker throughout the poem change dramatically, as do the moods of the sea. The irregular, undesirable rhyme is representative of these inharmonious moods and struggles.
Natural Processes are actions or events that have natural causes, which result in natural events. The three main coastal environment processes that operate at Muriwai are Coastal Erosion, Coastal Transportation and Coastal Deposition.
