'Evaluate how the Box Hill area is influenced by human activity'.

The title for this piece of coursework is 'Evaluate how the Box Hill area is influenced by human activity'.

The 'influence by human activity' reflects the way that humans utilise the Box Hill area and the effect that leisure and tourism have on the surrounding environment.

Location Map:

Box Hill is located in Dorking, Surrey, England.

. 225 MY : Weathering and erosion of very old folded rocks on an area of land.

2. 175 MY : Continued weathering and erosion on land in the north; deposition of weathered rock in the sea covering the area to the south.

________________________________________________________________

3. 120 MY : Continued erosion of the land as it is slowly uplifted and deposition in the sea as the basin gradually deepens. The size of the weathered rock fragments has varied- clay or sand at different times.

_________________________________________________________________

4. 50 MY: Deposition over the whole of this area, which has become submerged under water- including the deposition of chalk.

_________________________________________________________________

5. 25 MY: Alpine earth movements (Orogeny). The movement of the earth 's crust, which formed the Alps, also folded these rocks (but much more gently) and exposed them as land.

6. Present : Continuing weathering and erosion of the rocks since the folding and uplift. The clay (which forms valleys and low ground) has been eroded more than the sandstone and chalk, which form hills.

The importance of Chalk to the Box Hill area:

Over many hundreds of years, there has been a constant build up of rocks in the south-east of England, including,

> Clay,

> Sandstone,

> Weald Clay,

> L.R. Greensand,

> Gault clay,

> Chalk, and

> London Clay.

However, due to synclines, anticlines and present weathering, these layers of deposited rocks have been eroded and exposed, forming hills.

Box Hill is an area which lies on a layer of exposed chalk, meaning that the importance of chalk here is essential.

755:

We have chosen to study grid square 1755, as it contains Box Hill Country Park and its surrounding area. It is a popular area, which is frequently visited and can be easily accessed by the A24 and by the local train line. The peak of Box Hill, also indicated in the grid square, is a place where people come to see the incredible views of the downs.

Another reason why we chose this particular grid square was because of all the possible tests that we would be able to do, and all of the things there are to measure.

What we decided to measure:

> Primary Data:

Test

Reason

Noise pollution

We have chosen to measure noise pollution because of the vast amount of noise that emerges from the A24.

Traffic survey

We have chosen to measure traffic due to the A24 being visible from the mid-point of Box Hill, thus making the number of vehicles easy to measure.

Footpath Erosion

We have chosen to measure footpath erosion, as there is a long footpath in the area, travelling from the bottom of Box Hill, to the top of Box Hill.

Bi-Polar Landscape assessment.

We have chosen to assess the landscape because of the fantastic view which is visible from the top of Box Hill.

The aims of my investigation are to study the Box Hill area in order to answer the following questions:

> What happens to the levels of noise as we travel further up Box Hill?

> What is the volume of traffic on the A24?

> What effect does trampling have on the main footpath?

> What is the landscape like at the top of Box Hill?

> How accessible is the area?

> How is the area managed?

Noise Pollution:

Method:

Using the sound level indicator, we recorded the average noise level on a chart, and also took down the highest and lowest reading for each location. Three readings were taken:

. At the bottom of Box Hill by the A24;

2. Halfway up Box Hill;

3. At the top of Box Hill.

Type of data:

Primary Data

Effectiveness

This technique was quite effective, as it was simple and easy to follow.

Problems:

Other noises, such as the wind blowing may have affected the results and made the reading higher than it actually was.

Limitations:

Everyone has to be silent, as any other noises that are picked up will affect the results.

Traffic Survey:

Method:

For a period of 10 minutes we recorded, onto a chart, all of the vehicles passing Ryka's Diner on the A24 and then worked out estimates for the amount of traffic per hour and per day.

Type of data:

Primary Data

Effectiveness:

The method was quite effective as we had a good view of the A24 from the mid-point of Box Hill, and we could see the numbers of vehicles that passed us. However, getting the results were difficult.

Problems:

Cars we going too fast, and were therefore difficult to count.

Limitations:

Because the A24 is such a big road, we could only count vehicles going on one side of the road at any time. This meant that we had to exchange results with someone who was measuring the traffic on the opposite side of the road.

Also, our traffic survey was done in the afternoon. More surveys were needed to be conducted in order to achieve a more accurate outlook of traffic that passes Box Hill per day. E.g. there would be more traffic travelling on the A24 at 7:00am than perhaps 1:00pm.

Footpath Erosion:

Method:

In small groups, using quadrats, a ruler and tape, we recorded the vegetation types, vegetation cover, vegetation height and footpath depth on each side of the footpath in 7 locations. This was done in 5 positions, from the beginning of the footpath to the top of Box Hill.

Type of data:

Primary Data

Effectiveness:

Quadrats only give you a % vegetation result for a certain part of the footpath; therefore, it does not give you an accurate result for the footpath as a whole meaning that the method was not that effective.

Problems:

This test took too long to complete.

Limitations:

Because there were so many positions that needed testing, we had to split up in small groups. This meant that we had to exchange results with one another, and other people's results may not have been as accurate.

Bi-Polar Landscape assessment:

Method:

We must complete the Bi- Polar landscape analysis sheet by carefully observing the landscape off and around the viewpoint at Box Hill. We must then put numbers in the suitable boxes in the table depending on our views. Our results as ...
