Familiar Fieldwork - Physical Flashcards
What is the title?
To Investigate how the River Tillingbourne changes downstream
What is the theory/Hypothesis?
River velocity, width and depth will increase downstream - Bradshaw model
What was the risk assessment?
Drowning - water was shallow
Weather - waterproofs & sunscreen
Slipping - wellies
Weirs Disease - hand sanitiser & long trousers
What was the Location?
Tributary of the River Wey
Source - Leith Hill
Why was the site suitable?
Close to school
Close to villages
Alongside main roads = easy access
What sampling method did we use?
Stratified - Find sites
Systematic - across river channel
What were the disadvantages of the sampling method?
Stratified - time consuming, bias
Systematic - miss smaller patterns
What were the advantages of the sampling method?
Stratified - accessible locations, can be combined with systematic
Systematic - shows changes over time, reliable and avoids bias
What Primary Data did we collect?
Velocity, Width, Depth
Field Sketch
What secondary Data did we collect?
Land use survey
OS map
Environment agency
FSC data
How did we present our data?
Cross section - width and depth
Bar graph - velocity
Annotated photo
What was our conclusion?
Didn’t follow Bradshaw’s model because of human interference
What was the human interference?
Abinger Hammer was wider than expected
Secondary data - human interference to provide water for the Abinger mill in 16th century
Why were we limited?
Only at the site for one day
What were our improvements?
Collect data at different times of the year
Increase number of sites
Take readings at more frequent intervals
