Walton On The Naze

Question 1

Outline why Walton on the naze was a suitable location for your investigation.

Answer 1

One advantage is that Walton on naze is that it’s 90 minutes away this means that we can get their quicker therefore we can stay there for longer as a result we can have a better conclusion and have more data. Another advantage is that it’s being managed on a variety of ways this means we can compare their effectiveness.

Question 1

Risk faced in carrying out your investigation - Cliff collapse

Answer 1

At all times we ensured we stayed at 5 metres from the cliffs. This prevented us from falling off the top of the cliffs, or the cliffs falling onto us whilst working on the beach. We worked in groups at all times and we were accompanied by staff so we would be able to quickly raise an alarm if the need arose.

Question 2

Risk faced in carrying out your investigation - Drowning

Answer 2

Trip is scheduled for a time when it is a low tide. Students must stay away 2m away from the sea at all times. Have teachers in a 10:1 ratio to monitor students.

Question 3

Risk faced in carrying out your investigation - Getting lost

Answer 3

Regularly we will ensure head counts and students should stay in their groups with a teacher supported at all times. All the students have the emergency contact number.

Question 4

Sediment accumulations - How will the method be carried out?

Answer 4

Lay your tape measure out along the length of the ground from the sea walk out to sea, stopping around 2M from the water edge. Record this length. Starting from the sea wall measure the height from the top of the groyne down to the beach with a meter ruler. Repeat this every 10M along the length of the groyne recording the height every time. Once you have done this on one side of the groyne repeat the process on the other side of the groyne.

Question 5

Sediment Accumulation-Justification for inclusion and application

Answer 5

Groyenes are meant to prevent longshore drift and trap sediment. In theory, the beach width will be shorter and the beach height will be lower on the side of the groyne matieral is being removed from (zone of depletion). The reason we will stop our measurement 2 meters from the waters edge to minimise the risk presented to us

Question 6

EQS - How will the method be carried out

Answer 6

1)Go to the groyne and look at them.
2) Look at each question on the survey and tick the box that best describes the defence.
3) make sure you do this on your own.
4) repeat the process for the sea wall, rock armour, managed retreat.

Question 7

EQS - Justification for inclusion and application

Answer 7

We are doing this so we can compare the flat edges and see which is more effective. We do this independently because it is based on our opinion we don’t want to be influenced by others.

Question 8

Field Sketches - How will the method be carried out

Answer 8

A) go to the site where the groyenes are.
B) note down the tidal position, weather,time and date.
C) facing back towards the end draw a simple sketch of the coastal management and any evidence of Ericsson annotate sketches with detail about what can be seen.
D) repeat for site 2 : managed retreat and rock armour.

Question 9

Field sketches- Justification for inclusion and application

Answer 9

It is important to note and other and tidal positions and this can defend the way the area looks and the overall quality of our sketches. Annotated sketches provide a record the quality of the defences and there can be compared.

Question 10

Strengths of investigation

Answer 10

-Field sketches allowed us o focus attention on the key factors relevant to our investigation
-measuring beach height done in groups reducing the risk of human error.
-sketches also provided a visual representation
-collecting primary data gave us an idea about what the location was like.

Question 11

Weakened of investigation

Answer 11

EQS was based on opinion rather than any scientific evidence- subjecting and unreliable data.
Groyenes were in such bad condition that it was difficult to measure beach height against them because it n places bits were missing
Only looked at one groyne and one section of field work - might not be typical of other Groyenes / sea wall in area.
Possiblr Human error some people can’t measure with the stick?
Results change over the days
