(ii) Pebbles shapes will be rounder and textures smoother in Amroth as well.
(iv) Further east beach sizes will increase, where the stones are moving across the coast.
2. The advantages of people’s impact on the park outweigh the disadvantages.
3. Towns inside of the National Park are more populated than towns outside the National Park
Method
To test our hypothesis we used different methods and pieces of equipment, this involved a lot o group work.
Our first hypothesis was that”erosion will occur as the stones and pebbles rub together resulting in them shrinking and forming sand. This is likely to make the pebbles and stones smaller at Amroth than the other beaches west of it.“ In order to test this we used 30m tape measured and got 20 random pebble samples from Amroth and Saundersfoot. We measured the collected pebbles using callipers, we then combined all our results making a hundred different pebble samples.
(6)
There were however a few variables that could mean that this method isn’t completely reliable. The variable was that only one hundred samples were taken due to the limited time period. Had we taken more samples the results would have been more accurate. In addition due to beach nourishment, there had been pebbles on wither the beach or the beach further west to it. This caused for the pebbles to not be of an accurate size. The result we results we were after was for Amroth’s pebbles to be smaller than those form Saundersfoot.
We tested the theory that” average beach pebble’s shape and texture will be smoother and rounder at Amroth“ by using callipers to find out the roundness of the pebbles using numbers 1-5 to say how reliable. The pebbles roundness were judged by whoever picked them up. Therefore their judgement could vary to someone else’s judgement.
To test our theory that ”Beach size will increase in beaches further east, where the stones are travelling across the coast“ we used a measuring tape to measure the beaches length from the start of the pebbles to the sea wall. We then compared the length of the beaches from the west to the ones in the east, to see if the lengths of the beaches further east compared to the beaches in the west. I then needed to find out whether the depth of the beaches further east were increasing, compared to the beaches in the west. This was tested by using a clinometer.

To test my second hypothesis which was that ”the benefit of people’s impact on the environment is greater than the costs“ we had to weigh out the pros and cons of people’s impact on the environment.
We did an environment assessment by ticking and crossing boxes by rating the area on it being:
Quite-Noisy Pleasant-Unpleasant Distinctive-Ordinary
Friendly-Unfriendly Well kept-Neglected Exciting-Dull
Healthy-Unhealthy Varied-The same Stimulating-Depressing
Safe-Dangerous Clean-Filthy Open-Enclosed
Tidy-Untidy Beautiful-Ugly Welcoming-Hostile
Attractive-Unattractive Homely-Impersonal Like-Dislike
Interesting-Boring Colourful-Drab Go to-Avoid
The data was made based on people’s personal opinions so the data could vary to other peoples.
Finally to test the third hypothesis,” towns inside the national park are more populated than towns outside of it. “I had to do a pedestrian count which consisted of counting pedestrians as they walked past on the street within a certain amount of time. We then did a traffic count which was counting vehicles when they went past but also noting the kind of vehicle e.g. care, vans, buses, coaches and lorries.
A disadvantage was this was down to the reliability of class mates accurately gathering the data for the pedestrian count.
Environmental Survey
(Hypothesis 2)
TENBY
Total = 22
PEMBROKE
Total=33
Saundersfoot
Total = 38
My hypothesis was proven correct as the benefits of people’s impacts on the environment are greater than the costs. This was shown in my survey by a majority of benefits and very few costs. The only negative thing that stands out from my data is that Tenby was marked ugly and impersonal and Pembroke impersonal. These results are based on opinion so they can therefore be debatable. Overall Saundersfoot appeared to be the best beach followed by Pembroke and then the worst being Tenby as shown in the table:
Population- traffic and Pedestrian counts
(Hypothesis 3)
We used the mean of all five groups of data in my class. We tallied the following in 10 minutes in each town:
Tenby- Inside the National Park
Saundersfoot- Inside the National Park
Pembroke- Outside the National Park
My prediction for this hypothesis was proven correct by my data. It shows that in general Pembroke (a town outside the National Park) was more populated than Tenby and Saundersfoot who are both within the National Park. However Tenby had a far superior pedestrian count than those of Pembroke and Saundersfoot.
Conclusion
All my hypotheses with the exception of hypothesis were proven to be correct. However I don’t feel that my third hypothesis was incorrect but that the data may have been incorrectly recorded in the specific task.
Hypothesis 1.i, 1.ii, 1.iii all relate to each other as the pebbles and stone are getting smaller and rounder because of Long shore drift they are causing a build up of beach material on Far East beaches.
If I was to do this particular study again I would change various factors such as extending the length of the trip, vary the hypothesis, increase the amount of data that I collected and also try to use more sources.
In conclusion Pembrokeshire National Coast Park can be best managed by supplying the demands of as many people as possible as well as getting a good balance of the needs and wants of the locals and tourists and supervising the coastal processes also by acting against that could be dangerous or harm the park.
