I will now draw up a table to show all the types of data collected, it’s purpose, method and limitations.
Data Presentation
I will now present the data I have collected at the 6 different sites I have visited and I will try and use a different way of presenting each site.
Car Park Survey
I will now draw a table to show the % usage of the car park during times during our visit.
I will now create a tally to show the origin of visitor’s tax discs in a table.
I have decided to use a simple table for this survey because it is very simple and it is good to use if I have a large amount of results.
Beach Work locations 1+6
For the beach work I have done I will calculate the mean sizes for length, width and depth of 10 pebbles at 3 points (near sea, middle and back of beach)
Location 1 (Start of beach at end of double dykes)
By the sea
Mean length: 3+4+5+4+2+6+4+5+6+5/10= 2.6cm
Mean Width: 2+3+3+1+1+2+3+2+5+2/10= 2.15cm
Mean Depth: 1+2+4+1+2+3+0.5+1+2+1/10=0.95cm
Middle of the beach
Mean length: 2+1+2+4+1+2+3+5+6+2= 4.4cm
Mean Width 1+2+1+0.5+3+4+2+4+3+1/10=2.4cm
Mean Depth: 0.5+1+0.5+1+2+1+2+1+0.5+1/10=1.75cm
Base of Cliff
Mean length: 4+5+3+4+5+2+7+8+6+4/10=11.1cm
Mean Width: 2+3+4+2+1+1+5+7+5+3/10=3.3cm
Mean Depth: 1+2+3+6.5+1+2+1+2+1+0.5/10=2cm
Location 6 (Cliff face at end of beach)
By the sea
Mean length: 4+3+5+2+4+6+2+2+4+3/10=3.5cm
Mean Width: 2+1+3+2+1+2+3+4+2+1/10=2.1cm
Mean Depth: 1+2+1+0.5+1.5+2+1.5+0.5+1.5+2=1.35cm
Middle of the beach
Mean length: 7+5+7+3+5+6+5+6+5+4/10=5.3cm
Mean Width: 4+7+4+3+3+5+4+3+4/10=3.7cm
Mean Depth: 4+1+1+0.5+1+1+1+1+1.5+/10=1.2cm
Cliff foot
Mean length: 15+9+11+9+6+16+12+8+12+10/10=10.8cm
Mean Width: 12+4+4+9+4+8+7+8+7+4/10=6.7cm
Mean Depth: 1+2+3+0.5+1+1+1+1.5+2+2.5/10=1.55cm
I will now calculate the mean volumes for the rocks at each of the three areas at each location.
Location 1 (Start of beach at end of double dykes)
Mean Volume of rock by the sea: 2.6cm x 2.15cm x 0.95cm=5.3105cm (cubed)
Mean Volume at middle of the beach: 4.4cm x 2.4cm x 1.75cm= 18.48cm (cubed)
Mean Volume of rock at cliff foot: 11.1cm x 3.3cm x 2cm=73.26cm (cubed)
Location 6 (Cliff face at end of beach)
Mean volume of rock by the sea: 3.5cm x 2.1cm x 1.35cm= 9.925cm (cubed)
Mean volume at middle of the beach: 5.3cm x 3.7cm x 1.2cm= 23.532 cm (cubed)
Mean volume of rock at cliff foot: 10.8cm x 6.7cm x 1.55cm= 112.158cm (cubed)
This is a graph I have drawn to show the mean volume of rocks at location 1 and I will do the same for the rocks at location 6.
This is a line graph to compare the increase in Volume of the rocks at location 1 and 6 this is my data presentation for the beach work locations. I have chosen to use bar charts in this exercise because it makes it easy for comparisons and it gives a good idea about the difference of volumes in between the rocks.
Environment Quality Survey
I will now show the data I collected in the environment quality survey and I will add the scores up to calculate a total score for each place and I would show this as a % total.
Site 1
Site 2
Site 3
The numbers which are highlighted in red show the scores I gave for each site.
I will now add up the scores and make a total score for each site:
Site 1= 29/50=58% positive
Site 2= 46/50=92% positive
Site 3= 22/50= 44% positive
I will now do a pie chart for each Site to show the % positive and negative.
I have chosen to use pie charts for this exercise because it gives the reader a clear outline of which is stronger in positive and negative and it is good if I have only two results so it is the best choice.
This is my data presentation for the environmental quality survey.
Path Survey/Vegetation Transect
When doing the data presentation for this part I will have to consider the varying proportions of bare ground, broad leaved plants and grasses (narrow leaf).
This is a graph to show the percentage of bare ground and I will also do one for the broad leaved plants, grass and height of vegetation.
I have now drawn up a bar chart to compare each metre across the path to show how trampling affects the area.
I have used bar charts to illustrate this data because it is easy to show percentages on this format and it is easy to show progression.
This is my data presentation for the path surveys.
Pedestrian Count
In the pedestrian count I collected the number of people walking through a certain path in Hengistbury Head for 3 hours if all the groups added there times together, these are the collected results.
I have now drawn a line graph to compare the amounts of people walking through each site at hengistbury head during the day.
I have chosen to use a line graph to show my results because it lets me put up many different results on one graph which is good for comparisons. This is the conclusion of my Data presentation.
Data Analysis
The data I have shown in my data presentation shows many different parts of geography for example long shore drift for the Volume of stones and trampling and weathering for the foot path survey. The Car Park Survey shows that Hengistburry Head is used by mainly local people and this is shown in the table I produced where most of the people came from Bournemouth which is relatively close. In the beach work location exercise the rocks at location 6 which was further down the beach show that the rock size increases which is the effect of long shore drift and erosion is the main reason why only small rocks are washed on to shore and the large rocks are on the cliff foot. On the environment quality survey it shows that the man made sites are normally getting a bad response and the natural sites are more positive for people and they are a lot better. On the path Survey it shows that the middle of the path faced the worst of the trampling while on the edges of the path there laid more grass and broad leaved plants. Then the Pedestrian Count showed that the footpath by the sea was the most used path which is a favourite of elderly people and the headland was also popular during mid day. I think the management of Hengistbury Head have done well to manage the attraction and I think they have spent their money well. I think this because there seems to be no over crowding at Hengistbury Head and all there sea defences seem to be in good order and I see now problem with them at all. They have also tried to preserve wild life in the area and I think this is a very good idea because it attracts more tourists. I think the management of Hengistbury Head could be improved because it could be catered for a wider range of people and this would help reel more money in for sea defences etc they have done this in places like Devon and Cornwall who also suffer from Cliff erosion. The limitations I had to my work is that I only had one day to carry out my exercises and this meant that my results may not have been that accurate because I did not have at lease two or three sets of results. I also think that the weather was a determining factor in my exercises and this may have also changed my results. Then finally the last limitation to my work is the aspect of how new these sea defences are because some may have been better than others if they were newer and in better condition so the length of life of some of these defences may have been a factor which could have lead to a limitation to my work.
