Q

How was the secondary source used in the fieldwork project?

A

The map allowed us to see where we could best access the river, helping us plan sites along the full course of the river.

Q

List some hazards that may be encountered during the fieldwork project. What precautions would be taken to prevent them becoming an issue?

A

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.

Q

How would you go about measuring channel width?

A

Measure the river width using a tape measure

Keep tape taut

Record 3 widths 5m apart at each site

Record in m and cm

Q

How would you go about measuring depth?

A

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.

Q

How would you go about measuring velocity?

A

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

Q

How would you go about measuring bedload size?

A

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.

Q

Which bar graph will be used for the paper? What is the title, labels, and scale of this graph?

A

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.

Q

How would you interpret the trend of the graph?

A

Explain the conditions at different sites, making sure to quote figures and any unique aspect of each site.

17
Q

How could you extend the scope of the fieldwork project?

A

Test more features
Test river gradient
Flow meter to test discharge
Test other rivers
Test river at different times of the year

18
Q

What should you remember when drawing a graph?

A

Title- ‘a bar graph to show how cross sectional area changes down the course of the curly burn river’

^Remember to include type of graph

Make bars as accurate as possible, be careful not to go outside lines when shading.

Label axis using exact terms used in table, including units.
