Why is the Physical Fieldwork in Malham?
Access to river
Public land
Accessible in 1 day
What’s an enquiry question?
An overall question we are trying to answer by doing fieldwork
Physical hypothesis
The velocity increases downstream
Smallest, roundest sediment will be found downstream
The cross-sectional area of the river increases downstream
Cross-sectional method Physical
Measure width of river from bank to bank
Measure depth in 10 systematic points along a tape measure using a ruler
Sediment Physical Method
Randomly pick out 10 rocks
Measure long axis using ruler and calculate mean
Compare each rock against the Power of Roundness scale and calculate mean
Cross-section sampling method
Systematic, stratified, pragmatic
Accurate representation of river
Load definition
Sediment deposited and transported by river
Cross-sectional area definition
Area that river channel occupies
Sediment sampling method
Random
Reduce bias
Sampling methods
Systematic - collecting data in an ordered way
Stratified - representative sample
Pragmatic - based on practicality (easy / safe to get to, accessible)
Random - randomly choosing sites to collect data (no bias)
Advantages and disadvantages of cross-sectional area method
Easy, accurate
Only represents one specific point, requires entry into river (increases risk)
Advantages and disadvantages of sediment method
Quick, easy, no technical equipment required
Could be bias, subjective
Data presentation of cross-sectional river method
Channel analysis
Easy to compare, includes all data, visual representation
Time consuming
Data presentation of sediment method
Bar charts / pie charts
Easy to compare and read
Could be put onto a map to show location of results (proportional symbols)
Physical Fieldwork ethical consideration
Not disturbing environment, impact on countryside users
Aware of how to act professionally, keep to path as much as possible
Why is the Human Fieldwork in Leeds?
Accessible in 1 day
Areas are within walking distance of each other
Public land Accessible
3 locations from Human Fieldwork
Marshall Street, Brewery Wharf, Granary Wharf
Land Use Survey Method
Record land use of the buildings in the area using a key and annotate map with additional information
Environment quality survey method
Rate environment characteristics against criteria and count scores to get an overall number to compare
Risks and precautions in human fieldwork
Get lost - given a phone number
Danger around traffic - use pedestrian crossings, stay in big groups
Tripping up - stay on path
Regeneration definition
Revival of old and derelict areas
Cycle of deprivation
Loss of jobs > loss of money > poor housing > health issues > difficult to find work > difficult to pay bills > impact on children
Human field work sampling methods
All are
Stratified, pragmatic
Representative, practical, sensible
Advantages and disadvantages of land use survey
More up to date then Google street view, can get extra information such as new buildings being built
Can be difficult to work out use of all buildings, some buildings has multiple businesses
