Fieldwork - Physical

Question 1

Title

Answer 1

an investigation into how river variables change with distance downstream

Question 2

Aim

Answer 2

• investigate how width, depth and cross sectional area changes with distance downstream
• suggest reasons for change in cross sectional area

Question 3

hypothesis

Answer 3

with distance downstream, the corss sectional area of the river chalmadale will increase

Question 4

why its suitable for geo enquiry

Answer 4

• clear goegraphical link
• low risk
• data available
• compared to processes, theories and models e.g. bradshaw model

Question 5

location

Answer 5

• river chalmadale
• near lochranza
• isle of arran
• 3.35 miles in length

Question 6

location advantages

Answer 6

• easily accessible by foot
• short river so data can be collected in a day
• sites were accessible & shallow
• little human influence
• data gotten from 6 points

Question 7

theories

Answer 7

• erosion - processes and direction
• long profile of the river
• cross profile of the river

Question 8

data collection methods

width

Answer 8

• tape measure from bank to bank just above water surface
• tape held tight on ends
• light to carry

Question 9

data collection methods

depth

Answer 9

• systematic sampling - divided river width by 10 and took 11 equally spaced measurments
• placed meter stick vertically straight on rocks on river bed

Question 10

data collection methods

cross sectional area

Answer 10

• multiplied the depth by width
• not fully accurate bc it didnt take range of depths into account

Question 11

risks

Answer 11

slipping/falling into river = drowning or death
* shoes with good grip
* worked in groups
* staff checked safety first
poor weather conditions = hypothermia:
* staff had first aid training
* had lots of layers

Question 12

shapes located on a map

Answer 12

• clearly see downstream changes
• make links
• **can be cluttered
• keeping same scale means some drawings were hard to draw**

Question 13

cross sectional area

Answer 13

• site 1: 0.24m²
• site 3: 0.56m²
• site 6: 1.63m²

Question 14

width

Answer 14

went from 2m to 11m

Question 15

depth

Answer 15

• varies, but all sites were shallow
• shallowest: 12 cm
• deepest: 29 cm
• maybe bc had to be below welly height
