Component 3: Applied Fieldwork Enquiry - Methodological Approaches explained
This methodological approach asks you to detect change in a river or coastal landform by comparing what you record in the field now with historical evidence held in maps and photographs.
Read the full explanation
First define the landform and a measurable property, such as the position of a river meander's outer bank, the width of a beach, or the retreat of a cliff line. Collect current evidence by field sketching, measuring with a tape or GPS, and photographing from a fixed viewpoint. Then obtain historical evidence: an older Ordnance Survey map edition, an aerial photograph, or an archived ground photograph of the same place. Compare like with like by aligning scale, orientation and datum, and by identifying fixed reference points such as a bridge, building or grid line. Record the direction and approximate size of change, note the limitations of each source, and explain how confident you are in the comparison.
Your focus
- Describe a method for collecting current evidence of a river or coastal landform.
- Explain how historical maps or photographs are compared with current evidence to identify change.
- Evaluate the limitations of the comparison and justify a conclusion about confidence.

Marking Points
- Defines the specific river or coastal landform and the measurable property being tracked, such as bank position, beach width or cliff-line retreat.
- Describes how current evidence is collected in the field, for example field sketching, tape measurement, GPS points or photographs from a fixed viewpoint.
- Identifies appropriate historical evidence, such as an older Ordnance Survey map edition, an aerial photograph or an archived ground photograph of the same location.
- Explains how sources are aligned for fair comparison, matching scale, orientation and datum and using fixed reference points such as a bridge or building.
- States the direction and approximate magnitude of change between the historical and current evidence.
- Evaluates the limitations of each source, including map generalisation, photograph distortion and differences in date or season.
- Reaches a justified conclusion about how confident the comparison is and what further evidence would strengthen it.
Examiner Tips
- 💡Name the landform and the exact property you measure before describing the method.
- 💡Explain how you align historical and current sources so the comparison is fair.
- 💡Finish with a judgement on confidence and the limitations of your evidence.
Common Mistakes
- Compares a current measurement with a historical source of a different scale or orientation without realigning them; match scale, orientation and datum first.
- Treats a single photograph as proof of change without a fixed reference point; anchor the comparison to a recognisable feature such as a bridge or building.
- Describes the landform in general terms without naming a measurable property; specify what is being measured, such as bank position or beach width.
- Ignores the date or season of the historical source; state when it was captured and how that affects the comparison.
