Hi,
For my geography coursework I am investigation grain size, slope angle and distance between each slope (each slope was identified using ranging poles) along Chesil Beach. As I also need some theory behind what I am investigating, I was wondering whether people know whether you guys know any theory behind the sediment sizes, slope angle and distance between each slope on a beach profile.

I also need some theory behind the formation of spits/tombolos and barrier beaches and if there is any pattern in grain size etc on these features, so if anyone has any please post up!

The AQA A level Geography textbook has some useful stuff on coasts, perhaps ask your teacher when you get back?
Your coursework sounds very complex! I'm not really sure what I'm doing mine on yet... Might do something to do with deprivation and housing in the N/S divide but to be honest I'm still working on my hypothesis and question!
I think sediment size directly correlates to the energy and force of the water, don't hold me to that though! (It's been a while since I read through my water cycle notes).
The formation of spits should be quite easy to come by, you can use Google and websites as long as you keep a track of where you found your information and put it in your bibliography. The textbook I mentioned has a really detailed section on 'Spits, tombolos, bars and barrier-beaches', it also has some theory on grain size, 'The larger the size of the material, generally the steeper is the gradient of the beach (around 10-20 degrees).' etc.
Don't be put off by how thick the textbook is! Chapter 3 is on Coastal systems and landscapes
Hope this was slightly helpful...

Hi I am doing my coursework on chesil beach too!!! Wondering if we could help each other? Also how did you measure slope angle?

Hey! I'm sorry for the late reply! and sure that would be great. For slope angles we use a clinometer which was a more precise piece of equipment to measure each slope angle. I'm representing that data on a graph using my protractor so you can actually see the changes in slopes along the beach profile. It almost looks like a picture from the side of the slopes

Thank you for the reply! What was the general trend in sediment size you observed as the slope angle increased?

Don't quote me on this but I have just been on my geography yr 13 field trip and when we looked at sediment size, the main trend was the closer to the water the particles were the smaller they were. (Water uses hydraulic action, attrition and abrasion to make the particles finer).
Good luck! I am also struggling with my NEA but mine is on economic north south divide Arghhhhhhhh

Thanks for replying - your NEA sounds complex but good luck!! When is your deadline?

Hi have you finished yours?
We haven't even started our data analysis. We've done everything but data analysis. My geography teacher went to an AQA coursework course because there was so much confusion from the exam board about the whole NEA. My school now has extended our internal hand in date to after our January exams. Luckily enough my data shows what I want it to show!
I know the actual hand it date for coursework is usually spring next year?

Generally the further away you are from the sea front, the larger the sediment sizes so the greater the slope angles, that's backed up by loads of theory. Even if your data doesn't show this you can use theory from Chesil beach to explain why!

Yeah our internal one is before Christmas which is a bit soon. Mine is on Chesil Beach too but I'm really not sure how to answer my research questions. Our teacher hasn't been in for four weeks...

Hey folks, i understand that you will have all finished your NEAs by now but im about to start mine and am doing it on a sandy beach in Bournemouth any ideas what i could measure because its a sandy beach rather than a rocky one meaning that i cant really measure sediment size?? thought my title could be something along the lines of how does the beach profile change.. no clue really. any advice would be much appreciated.

Finished it a good while ago so advice might be dubious lol - but could you measure the height of the sand at the groynes? Then you could talk about how longshore drift affects the beach profile? Good luck!
