Fieldwork - Physical Flashcards
1
Q
Title
A
an investigation into how river variables change with distance downstream
2
Q
Aim
A
- investigate how width, depth and cross sectional area changes with distance downstream
- suggest reasons for change in cross sectional area
3
Q
hypothesis
A
with distance downstream, the corss sectional area of the river chalmadale will increase
4
Q
why its suitable for geo enquiry
A
- clear goegraphical link
- low risk
- data available
- compared to processes, theories and models e.g. bradshaw model
5
Q
location
A
- river chalmadale
- near lochranza
- isle of arran
- 3.35 miles in length
6
Q
location advantages
A
- 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
7
Q
theories
A
- erosion - processes and direction
- long profile of the river
- cross profile of the river
8
Q
data collection methods
width
A
- tape measure from bank to bank just above water surface
- tape held tight on ends
- light to carry
9
Q
data collection methods
depth
A
- systematic sampling - divided river width by 10 and took 11 equally spaced measurments
- placed meter stick vertically straight on rocks on river bed
10
Q
data collection methods
cross sectional area
A
- multiplied the depth by width
- not fully accurate bc it didnt take range of depths into account
11
Q
risks
A
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
12
Q
shapes located on a map
A
- clearly see downstream changes
- make links
- **can be cluttered
- keeping same scale means some drawings were hard to draw**
13
Q
cross sectional area
A
- site 1: 0.24m²
- site 3: 0.56m²
- site 6: 1.63m²
14
Q
width
A
went from 2m to 11m
15
Q
depth
A
- varies, but all sites were shallow
- shallowest: 12 cm
- deepest: 29 cm
- maybe bc had to be below welly height
