Fieldwork Flashcards
What is an advantage of using the geographical enquiry process?
Easy to interpret which makes planning easier and more streamlined.
What steps are used in the geographical enquiry process?
Plan fieldwork data collection
Collect data
Processing and Presenting data
Analysing and interpreting data
Draw a conclusion
Evaluate the fieldwork
State the aim of the fieldwork project
To study the downstream changes of the curly burn river.
State 3 hypothesis for the fieldwork project
Width and depth increases with distance downstream
Velocity increases with distance downstream
Bedload size becomes smaller and more rounded with distance downstream
What secondary source was used in the fieldwork project?
OS Map of the curly burn 1:50,000 - Northwest of NI
How was the secondary source used in the fieldwork project?
The map allowed us to see where we could best access the river, helping us plan sites along the full course of the river.
What is the definition of hypothesis?
A statement that is believed to be true to be tested during an investigation.
What river was investigated during the fieldwork project? Where was it located?
Curly burn.
County Londonderry, flowing between Coleraine and Limavady
List some hazards that may be encountered during the fieldwork project. What precautions would be taken to prevent them becoming an issue?
Weather, e.g precipitation, temperature, wind, etc.
Consult a weather forecast, plus wear clothing fitting for the climate.
Drowning.
Don’t enter dark, deep water. Wear a life jacket.
Slipping, falling and hitting your head.
Wear appropriate footwear and a helmet.
Stabbed by ranging poles
Carry them upright
Disease, e.g whiles disease
Do not eat or drink in the river and cover open wounds. Do not interact with river rat.
Slippery uneven surface
Take care when entering the river.
How would you go about measuring channel width?
Measure the river width using a tape measure
Keep tape taut
Record 3 widths 5m apart at each site
Record in m and cm
How would you go about measuring depth?
Measure river width using a tape measure from waters edge to waters edge.
Divide this width by 6. This will give you 5 evenly placed sections along the tape.
Use a metre ruler to measure depth at 5 points across the river.
How would you go about measuring velocity?
Place ranging poles 10 metres apart.
Time the float with a stopwatch.
Repeat the experiment 3 times in left, middle and right channel to get an average time.
Work out average time. Divide 10m by average time = m/sec
How would you go about measuring bedload size?
You need to select an unbiased random sample of 10 stones from the river bed.
For size use callipers to measure the length.
Record in mm.
How would you go about measuring bedload shape?
Select an unbiased random sample of 10 stones from the river bed.
Use powers roundness index.
Which bar graph will be used for the paper? What is the title, labels, and scale of this graph?
Cross sectional area.
Title: A bar graph showing cross sectional area along the curly burn river.
Labels: y axis, Cross sectional area (m2). x axis, sites.
Scale: y axis, 0-4, 1 large square per 0.5. x axis, 6 bars.
