Data, information collection methods and sampling, The Three Key Questions…
Data, information collection methods and sampling
Beach transect 
Limitation: On the day of collecting my results there was quite a strong wind meaning that I struggled to keep the tape measure exactly straight. However, this happened on all the reading so this limitation is continuous throughout the results.
Justification: I used a beach transect to measure distances and angle measurements to help you investigate the shape of the beach. I used this technique to help answer my Key Question 2
Geolocation: I geolocated the data by recording the What 3 words. This gives me a 3 word combination which I can pinpoint on a map to locate where I took my readings for the Beach transects.
Sampling Strategy: I systematically recorded the beach angle between the groins at every 100 segments. I did this to get an average of high and low sides of the beach.
Method: I measured the beach transect by placing two ranging poles on the first increase off slope making sure they are inline with a tape measure to see how far up the beach the slope was. Then using a clinometer I measured the angle of the beach and the continued with that process until I reached the top of the beach. I continued this for 5 segments of 100m increments.
Ethical Considerations: I was ethical with my data collection by relocating my beach transect if there were people in the way in order not to disrupt their day.
Orange Toss
Justification: I used an Orange Toss to measure the rate of Longshore Drift at different locations on the coastline. This technique will be crucial to answer Key Question 2.
Limitation: One limitation of using an orange toss to measure the longshore drift rate in a certain area is obviously human error and not being able to repeat a certain variable. An example of this would be how far an orange went into the sea and the different mass of the orange. Another limitation was using a 20 meter tape measure which I found out was not long enough as after 30 seconds an orange had already travelled 26 meters and was continuously moving. This places a limitation on the equipment used.
Method: To measure the rate of Longshore drift I used an Orange Toss. This incluces throwing an orange into the sea and timing two minutes. After two minutes you measure from where you threw the fruit and measure with a tape the distance travelled.
Geolocation: I geolocated the data by recording the What 3 words. This gives me a 3 word combination which I can pinpoint on a map to locate where I took my readings for the Orange toss
Sampling Strategy: I took Orange toss readings in every segment of the beach between 2 Groynes to get a detailed map of how the Longshore drift rate has changed further down the beach. This sampling was done in a systematic way
Ethical Considerations: I was very careful not to interrupt or disrupt anyones day by throwing an orange into the sea and I also collected the orange afterwards to stop any littering.
Wave Count
Justification: I measured the Wave count to see if there was a significant impact from the waves. This data helps answer Key Question 2 and 3.
Method: I measured the Wave count by recording how many waves broke in front of me inside 2 minutes.
Geolocation: I geolocated the data by recording the What 3 words. This gives me a 3 word combination which I can pinpoint on a map to locate where I took my readings for the wave count.
Justification: I measured the wave count to see if the wave frequency has an impact on the coast and to see what coastal management strategies there are to contract the wave frequency.
Wind Speed and Direction
-
Method: I measured the wind speed by using an anemometer which calculated the speed in KM/H and I used a compass to work out where the wind was coming from.
Geolocation: I geolocated the data by recording the What 3 words. This gives me a 3 word combination which I can pinpoint on a map to locate where I took my readings for the Wind Speed and Direction.
Limitation: On the day there was a large amount of fluctuation of Wind speed. This was seen by sudden gusts. This is seen in the results and a causing limitation for the results I have.
Sampling Strategy : I took Beach transects in every segment of the beach between 2 Groynes to get a detailed map of how the wind direction and speed has changed further down the beach. This sampling was done in a systematic way.
Condition and Frequency of Coastal defences
Justification: I will use the condition of coastal defences to answer the key question 3 and this will asses how they are used to protect the coastline. The Frequency of coastal defences helps answer key question 1
Method: I measured the condition of coastal defences by having a scale from 1 being in the worst condition possible and 10 being its brand new. I measured the frequency of coastal defences by creating a tally system of what coastal defences there are in each segment.
Limitation: A limitation of working out the condition of coastal defences is that it is it is subjective to my opinion of how the defences look.
Geolocation: I geolocated the data by recording the What 3 words. This gives me a 3 word combination which I can pinpoint on a map to locate where I took my readings for the condition and frequency of coastal defences.
Sampling Strategy: I took readings in every segment of the beach between 2 Groynes to get a detailed map of how the angle of the coastline has changed further down the beach. This sampling was done in a systematic way.
Groyne Height
Justification: I measured groyne height to see how much material the beach defences collect and to see how much material is stopping from being taken down the beach by Longshore drift. This technique helps answer key question 2.
Method: I measured the groin height by using a tape measure and I measure the East and West side of the groin and we can see how the material has been built up on one side.
Geolocation: I geolocated the data by recording the What 3 words. This gives me a 3 word combination which I can pinpoint on a map to locate where I took my readings for the groin height.
Sampling stratergies: I measured the Groin height at every groin that bordered the 100 meter segments that I was recording my data in.
