Drawing a Beach Profile

top

To draw your beach profile

  1. Draw yourself 2 axis along the bottom is the width mark in metres using a scale of 1 cm = 5 metres

  2. Starting at zero draw a line the length of the first section of your profile (you must have started at the sea) but at the angle that the section was. You will need to measure this using a protractor.

  3. Now starting at the end of the line you have just drawn do the same thing again. Remember to add the length of the next section on and measure the angle from the horizontal rather than the bottom axis.

  4. Continue this until you have drawn all the sections.

  5. Now colour you beach in yellow.

  6. Calculate the overall width of the beach, height of the beach and the slope angle and include it as a table on you sheet.

 

Some things to label on your profile:

  • Backslope  an area where a beach dips downwards at the back of the beach

  • Berm  the overall shingle ridge where storm waves have piled up shingle above the high water mark

  • Storm ridge  the fairly level terraces or ledges built up by storm waves at different levels ob the seaward side.

  • Swash zone  the first slope segment nearest the sea where waves are breaking and sending water up the beach

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Analysis of Beach Profiles top

(Put this as your overall title)

Take each beach profile in turn and write a paragraph to analyse the information you have got on the beach.

Analysis of Burton Bradstock beach profile

(this is the sub-title)

Write a paragraph about Burton Bradstock beach include the following:

  • The location of this site

  • A description of the beach - what it looked like see below

  • How many sections it had

  • How high it is

  • How wide it is

  • What the slope is

Use the following to help you

Burton bradstock beach is at the far Northwest end of Chesil beach. It is the only part of the beach that can be described as sandy and is the only part backed by cliffs. There are two main cliff types on either side of the main entrance. The furthest northwest is a vertical sandstone/limestone cliff ( this is where we did our profile). The one slightly to the southeast is Burton beach and is a sloping clay cliff.

*If you are going for a high grade you will need to include a beach profile for the sloping clay cliff as well. You will also need to talk about this in your analysis giving the same information as above and also comparing it to the sandstone/limestone cliff profile.

Analysis of West Bexington beach profile

Write a paragraph about West Bexington beach include the following:

  • The location of this site

  • A description of the beach - what it looked like see below

  • How many sections it had

  • How high it is

  • How wide it is

  • What the slope it

  • How it compares to the Beach Profile of Burton Bradstock

West Nexington lies around 6km southeast of Burton Bradstock but is completely different. It is still a normal beach and not yet a spit however is made up of shingle rather than sand. It has a berm, storm ridges and a back slope.

Analysis of Abbotsbury beach profile

Write a paragraph about Abbotsbury beach include the following:

  • The location of this site

  • A description of the beach - what it looked like see below

  • How many sections it had

  • How high it is

  • How wide it is

  • What the slope is

  • How it compares to the Beach Profile of Burton Bradstock and West Bexington

Abbotsbury is 6km southeast of west Bexington. At Abbotsbury where we did out profile chesil beach is still a typical shingle beach, but a little way along the coastline changes direction inland whilst the beach continues in a straight line. As it leaves the land it traps water behind it this is called the Fleet Lagoon and by leaving the land it is now a spit.

*Again if you are going for that high grade you will also need to include a profile of the second area at this site, which is, where the coastline changes direction at it becomes a spit. Again you will need to talk about this in your analysis.

 Analysis of Chesilton beach profile

Write a paragraph about Chesilton beach include the following:

  • The location of this site

  •  A description of the beach - what it looked like to see below

  • How many sections it had

  • How high it is

  •  How wide it is

  • What the slope is

  • How it compares to the Beach Profile of Burton Bradstock and West Bexington and Abbotsbury

Chesilton is 29km (18 miles) southeast of West Bay and 16km south east of Abbotsbury. At this point Chesil beach rejoins the land at the isle of Portland and becomes a special kind of spit called a tombolo.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Conclusion of Beach Profile Results   top

(Put this as your title)

Conclusions: the object of a conclusion is to try to summarise what we found out in relation to the original aims and hypothesis of the project. Also to include a geographical explanation for the findings and mention any limitations, anomalies or weaknesses of the data we collected.

Include the following in your conclusion in as much detail as you can:

Repeat what we expected to see happen to the height width and slope of Chesil Beach as you go from Burton Bradstock to Chesilton.

Write a detailed comment on what you saw happening to the height, width and slope of the beach from your results that you have drawn up as beach profiles.

 

For example include comments like:

As you can see from beach profile 1: Burton Bradstock the height of the beach started at 10 metres and at West Bexington it rose to 12 metres we expected this pattern.  Make sure you relate back to your beach profiles you could number them as figures or refer back to them by title.

Try to explain the results that you actually saw happen (this is the bit that you gets most marks for if it is really good)

 

You will need to explain why the beach may have got higher wider and steeper if it did.

If the beach did not get higher wider and steeper as we expected you will need to try and explain some reasons why it didn't.

You can use the following to help you do this you do not need to include every idea:

 

  • The equipment may have been inaccurate or used incorrectly by groups particularly over long sections of the beach.

  • We may have picked a 'freak' or abnormal line or profile to the rest of the beach in that area. This could have been overcome by completing more than one profile in each area however we were limited by time.

  • Throughout the day we were measuring the results the tide would have been going in or out. This would have altered the width or the beach however only by about 20 metres or so.

  • The way we have measure the slope from our diagrams means that Burton Bradstock appears really steep however this is not necessarily the case because Chesilton had large very steep sections however these are evened out by large very flat section. 

  • The beaches we had access to are not completely natural i.e. West Bexington was backed by a car park and a wall backed Chesilton.

  • The beach is continuously changing and therefore recent weather events i.e. winds and waves may have altered the shape of the beach.
