FIELDWORK : Dawlish Warren

Question 1

What primary data was used ?

Answer 1

• beach profiling
• sediment shape
• questionnaire
• warden interview

Question 2

What secondary data was used ?

Answer 2

• geology map

- OS map

Question 3

What quantitative data was used ?

Answer 3

• beach profile

- sediment shape

Question 4

What qualitative data was used ?

Answer 4

• questionnaire

- warden interview

Question 5

How and why was the beach profiling used ?

Answer 5

• used a clinometer and ranging pole
• measured the gradient of the beach each time the profile changes
• expected to see steeper profile on the west side of each groyne (LSD)

Question 6

What were the weaknesses to the beach profiling ?

Answer 6

• some people didn’t know how to use the clinometer = inaccurate readings

Question 7

How and why was sediment shape used ?

Answer 7

• pebble is selected on each side of groyne

- shape is judged using scale of roundness to see if groynes have an effect on LSD

Question 8

What were the weaknesses to the sediment shape ?

Answer 8

• subjective, one person may disagree about the roundness of a pebble

Question 9

How and why was the questionnaire used ?

Answer 9

• asked people about coastal management, which one is more successful

Question 10

What were the weaknesses to the questionnaire ?

Answer 10

• answers are subjective

- difficult to get good results as not many people were around

Question 11

How and why was the warden interview used ?

Answer 11

• interviewed him about coastal defences

- asked his opinion about which was better

Question 12

What were the weaknesses with the warden interview ?

Answer 12

• probably biased

- subjective

Question 13

How and why was the geology map used ?

Answer 13

• shows rock type
• helps us understand erosion rate
• helps choose range of sites

Question 14

What were the weaknesses with the geology map ?

Answer 14

• no human activity can be seen

Question 15

How and why was the OS map used ?

Answer 15

• hows human and physical features

- helps choose range of sites e.g. some with and without coastal defences

Question 16

What were the weaknesses with the OS map ?

Answer 16

• might be outdated and not show recent changes

Question 17

How did we choose our sites ?

Answer 17

• used geology map
• used OS map
• made sure sites were close enough so we could collect data on the same day
• did a risk assessment to make sure we would be safe and able to collect data

Question 18

What 4 ways did we present our data ?

Answer 18

• beach profile = line graph
• sediment shape = stacked column graph
• questionnaire = wordle
• interview = table of :) & :(

Question 19

Conclude your results

Answer 19

• data = groynes have prevented LSD to some extent
• map of DW = several groynes on spit to prevent erosion
• beach profiles = build up of sand on the west side of each groyne
• sediment shape supports statement as pebble shape is distributed
• data = communties have been affected positively and negatively
• photos = beach was closed, groynes were being fixed, beach replenishment
• makes are look unattractive and put tourists off affecting businesses
• questionnaire backs this up as people said DW didnt need coastal management meaning they didnt like it
• 4 people + groynes - it makes the beach bigger = more attractive
• 3 people + the sea wall - protected the railway line

Question 20

How accurate were your results for beach profiling

Answer 20

• somewhat accurate
• some human errors
• weren’t able to visit many places
• beach closed for maintenance
• accurate enough to show LSD

Question 21

How accurate was your overall conclusion ?

Answer 21

• somewhat accurate
• asked people + warden
• didnt know if they were local or tourists
• warden may be biased

Question 22

How reliable were your results ?

Answer 22

• warden +
• secondary data +
• photos +
• could reach different conclusion…
• different weather
• management strategies
