Assessment of the Movement of Material Along Deal's Beach
This was carried out at site 3 because there are groynes at site 3
which created an area within 2 groynes called a groyne box which I
could study in order to look at the movement of pebbles within a
confined area.

The purpose of this aim is to see the effects of Longshore Drift over
a longer period of time.
Theory Work
Groynes are structures that extend finger like, perpendicularly from
the shore. Usually constructed in groups called groin fields, their
primary purpose is to trap and retain sand, nourishing the beach
compartments between them. Groynes initially interrupt the longshore
transport of littoral drift. They are most effective where longshore
transport is predominantly in one direction, and where their action
will not cause unacceptable erosion of the down drift shore. When a
well designed groin field fills to capacity with sand, longshore
transport continues at about the same rate as before the groins were
built, and a stable beach is maintained.
Groynes are suitable erosion control measures where a beach is
desirable, and they are compatible with most recreational activities.
The beach fed by the sand trapped between the groins acts as a buffer
between the incoming waves and the backshore and inland areas: the
waves break on the beach and expend most of their energy there. Filled
groins provide this protection during normal weather conditions but
offer only limited protection against storm-driven waves. Groynes can
be found a t Deal.

Seawalls are solid structures built parallel to the beach for two main
reasons. One reason for building seawalls is to protect homes on the
coastline from the destruction of large storms such as hurricanes or
from the large waves they can create. Another reason they may be
Investigation on Coastal Erosion In Porlock Bay Aims ---- Aim 1: To find out if beach material is moved across Porlock Bay by longshore drift. Aim 2: To find out which type of sea defense is best for Porlock bay. If L.S.D. (long shore drift) were taking place I would expect to find: a) Deposition at one end of the bay and against any abstractions such as groynes. b)
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
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.

Sitting on the site of the former Florida tourist attraction, Circus World, in Haines City, Boardwalk and Baseball came to life as a result of Orlando-based textbook publishers Harcourt, Brace and Jovanovich desire to be a part of the theme park and entertainment business, in 1986. Feeling that the circus theme was losing its luster, HBJ closed the property and immediately started a complete makeover into a vintage, sports-themed entertainment park.
Good morning/afternoon ladies and gentlemen and welcome to the State Library of Queensland’s poetry celebration. It is my absolute pleasure to speak to you today.
The location of the study area is Silver Beach in Kurnell Peninsula, near Cronulla. It is located in the Sutherland Shire, south of Sydney Central Business District (CBD) and just directly south of Kingsford Smith International Airport. The area also has a historical significance as it is near the landing place of Captain James Cook on the 28th of April 1770 in Botany Bay.
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,
The hypothesis presented in a paper titled, “Barrier Island Formation”(Hoyt 1130), is as follows: Along a sand shoreline, wind will form dunes or ridges (depending on the type of material the beach is composed of). If there is a relative submergence, the area landward of the dune/ridge will be flooded to form a lagoon and the ridge/dune then becomes a barrier island. This would most likely occur when a stable shoreline with a well-developed ridge is engulfed by a relatively sudden transgression that does not erode or push the ridge landward (Ot...
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.
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.
Surfers, swimmers and sunbathers use beaches for recreation. People fish off beaches for food. Since many people take their vacations at the beach, lots of beaches in tropical locations are important to their country’s economy. Entire cities, regions and countries depend on the money tourists spend while visiting the beach. Beaches are naturally very dynamic places, but people try to control them and build permanent structures, such as houses, restaurants, shops and hotels, on or near the shore. The natural erosion and deposition of beaches becomes a problem. Beaches con disappear over time, or even over night during severe storms. Beaches are areas of loose sediment (sand, gravel, cobbles) controlled by ocean processes. Most beaches have several characteristic features. First are offshore bars, which help protect beaches from erosion. Next is the foreshore, which rises from the water toward the crest of the next feature; a berm. On low-lying shores, dunes form behind beaches. Dunes look like rolling hills of sand and are blown into place by the wind. New, smaller dunes are often changing shape as the wind continues to affect them. Waves and currents move the accumulated sediment constantly creating, eroding and changing the coastlines.
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.
People from all over the world go to beautiful beaches that are filled with water as clear as ice or as beautiful as diamonds. But, what will happen if we do not conserve the appealing sites that draw attraction to the public? Contaminated beaches has become a controversial issue to the public because of the causal problem, the harm to the people and marine animals, the government agencies supporting or opposing pollution, and the industries involved in creating such unlawful decisions. To create and find a solution, we must first find the core to the problem.
