Fieldwork help!
« on: October 16, 2014, 09:09:33 PM »
Hi
Just wondering if anyone can help me - got a few questions!

We are doing coastal field woke (edexcel a) and we did ground height measurements however another staff member thinks I've done it wrong.

As we look to the sea we did left (north) and right (south) at Hornsea (holderness coast) - most as a result have left / north higher. Is this right?

We also did wave frequency - timed same location for 5 min - then pupils have worked out average - what data presentation do people suggest?

Thanks all

AliceWJ

Hi regarding the data presentation have you tried GE graphs to do located bars for each of your sites to show ave no of waves - more than 13 (off the top of my head) shows they are destructive? Quite good to show how different areas have different types of waves which might affect rates of coastal recession in different places (eg due a headland refracting the waves etc). Sorry I can't help with your other question as don't know the area. Good luck!

Thanks - yeah destructive we had an average of 23! It was a wet and stormy day!!

 Am I right on the principle of groyne measurements - you look at the sea for your right / left?

Thanks

We do the same spec/question on coastal recession. We visited Norfolk and looked at three sites including Happisburgh. We recorded bipolar analysis of defences, land use mapping, lsd, slump plotting, beach profiles and wave rates. We have been working on 11 or more as a destructive per minute. And we used proportional circles on aegis to display the data.

Longshore drift from North to south so you would expect sand to be trapped to North of the groyne - so correct

Many thanks

I thought I was going mad when a more experiences teacher has told their class it's the other way around!

Just checked Google Earth to confirm and in places it does seem to show evidence of build up both ways so might depend where you actually measured. Go with your data, if that is what you measured that is what it shows, don't try to fit what you found to what you thought you would find.

Thanks - yeah a few were very similar etc its just the other teachers group have almost all them south being higher and I was thinking I was going mad in terms of had I done it wrong with my group. I have a feeling this other teacher hasn't collated or checked the results and some of the groups have done it wrong way around.

Thanks again!

Hi

I have collected data like this in Hornsea, you are correct the North is higher than the south. But there are some areas that it is the other way around - I think local factors play a role and human interference, plus the quality of the groynes - as other posts have said, go with your data and explain from there!

Hope that helps
