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 trowel and measured the

depth of the beach. We did this by digging until we met the clay and

then noted down our results as we got them.

Whilst measuring the depth of the beach we also did the angle. We

obtained the results by using a clinometer. To use the clinometer we

lined it up against a line of the first pole and pointed it towards

the second pole, using the sights to line it up against the

corresponding line on the pole.

Then we released the trigger to measure the angled and noted our

results down.

The results from these activities will help to answer the first key

question:

'What are the differences between the protected and the unprotected

beaches at Walton?'

These beach surveys will allow me to answer the first key question as

I will be able to compare the results from the survey and find the

difference between the protected and unprotected beach. As the results

form each survey should be different.

The benefits from doing these beach surveys are:

* I can get a good idea of the steepness of the protected and

unprotected beaches

* I can get an idea on whether it's a strong or week beach, and

whether it changes a lot depending on the beach being protected

and unprotected.

The problems from doing these beach surveys are:

  • Semaphore Beach Case Study

    1388 Words  | 3 Pages

    Semaphore Beach is affected by many factors such as natural processes and human impacts including marine litter and the discharge of stormwater. Therefore, several plans have been employed to ensure that the coast is supported through the method of counteracting erosion. However in the future, many management strategies have been put into consideration as well as the environmental, economic and social impacts as well as the predicted consequences. These impacts include traffic related incidents, noises and air pollution and the disruption of wildlife and the erosion of dunes. A method that should be considered for future management of the beach is the use of a concave sea wall, although efficient, this structure would be quite costly. Without the use of coastal management, Semaphore Beach would be unsupported, therefore negatively being affected by a variety of

    The whole island is in the shape of a giant square with white sandy beaches full of people sunbathing, swimming and fishing right on the shoreline. From the end of the hot pavement parking lot to shore of the beach is an ocean of soft white sand. The pearlescent white sand seems to know how to invade every nook and cranny almost as if it enjoys it. Walking around the beach on the fluffy whiteness surrounding the parking lot, the seagulls are fighting over scraps of food on the ground. “Sandy beach ecosystems provide invaluable services to humankind. Their functions have been exploited through history, with significant anthropogenic effects (Lucrezi, 2015)”. This white sandy beach is a beautiful refuge from the mundane grind of everyday life. The smell of the misty ocean air mixed with the sound of seagulls hovering above and kids playing is a tonic for the mind. The feel of the sand between their toes and the waves crashing over them as people swim in the water, or the jerk of a fishing pole when someone is catching a fish makes Fred Howard Park one of the best places to relax. Standing on the beach looking out on the water, people are kayaking and windsurfing. The lifeguards watching vigilantly in their bright red shirt and shorts, blowing their whistles when they see someone being unsafe. After a long day of swimming and laying around visitors head back over the soft white sand to the showers, in order to rinse off the menacing sand that clings to everything like a bad habit. Everyone rushes over the hot pavement burning their feet to reach their cars so they can put away their beach paraphernalia which is still covered in the white sand, nearly impossible to completely leave behind, so when they get home it serves as a reminder of where they were that

  • Barrier Beaches of Long Island, NY

    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.

    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.
