To Test if Longshore Drift is Taking Place Along Deal Beach on the Day of Our Visit
For this aim, we measured the wave angle. To do this, I laid a
protractor on the floor, and watched for about 5 minutes in which
direction the waves were travelling. I would look down on the
protractor, and note down the angle of the waves. I then worked out
the average angle.
We had to do measure the wave angle because it would show us in which
direction the longshore drift (if any) was taking place, therefore
resulting back to the title of the aim.

On the day of the visit, the weather conditions were probably the
worst conditions of the week. There was rain early on in the morning
and when we arrived, so we had to wait in the minibus for the rain to
stop. It did, and so we could carry out our investigation. The
temperature was 59 º, so not very warm. The cloud cover was about 80%,
so not much sunshine at all.
To measure the wind speed, I used an instrument called Anemometer
(fig.3). I basically held this instrument up in the air, and the wind
would blow onto its fan, and it would measure the speed for me. To
measure the wind direction, I held my handkerchief up in the air, and
recorded using a compass, the direction the handkerchief was facing,
and went to the opposite of that because that would be the direction
This shows that it is eroded at one end more which is a sign of long
To measure the depth of the river we had to get two ranging poles and
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.

The aircrafts equipment will record the speed of the wave and the travel time during air to calculate depth . Therefore LADS must be flown during hours of darkness to eliminate the errors caused by the reflection of the sun off the water, which return false reading to the aircraft causing inaccurate depth.
Ultrasounds use the same concepts that allow sonar on boats to see the bottom of the o...
In the article “A Tsunami, Where?” (2015). On June 2013 a storm have hit the East Coast in the U.S that results in tsunami. Over 30 tide gauges have reported similar tsunami conditions. The highest capacity was recorded in Newport located in Rhode Island. In addition, Conditions showed a conceivable torrent, even to the individuals who did not have the guide of the tide gages. Brian Coen was spearfishing at Barnegat Inlet in Ocean County, New Jersey he saw a solid outrush of water as the tide went out. Outrush conveyed jumpers over submerged rocks that serve as a barrier, the strong waves carried the three drivers but only two were harmed. However, Ebersole reviewed that before long, the current switched at the same pace. A close-by gage recorded
The purpose of this experiment was to see the effects of surface angles on the shape

Longshore drift is a process by which sediments are transported from one place to another. When this process occurs, beaches, spits and sandbars are accreted over time. If the process of longshore drift is altered by factors such as stronger winds and stronger currents, beach erosion begins at a faster rate and this may result in many serious problems. The main stakeholders of longshore drift are resort owners. They rely on people to visit their resorts and enjoy the beach. However, if longshore drift erodes too much sand, it can permanently deprive sand from the area, which can also threaten structures close to the shoreline.
sheer coincidence, a pleasant one though. Since they wanted to ensure that the taxi is provided on
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.
had been warned couple of times about me being late. Luckily the bus too was
