G43: Fieldwork: Enquiry Process
The geographical enquiry process: formulating questions and hypotheses, selecting appropriate evidence, identifying suitable locations, and carrying out risk assessment.
🔍 The Geographical Enquiry Process
Key Concept: Geographical enquiry is a structured investigation into a geographical question or issue. It follows a clear sequence: Question → Hypothesis → Data Collection → Data Presentation → Analysis → Conclusion → Evaluation. AQA requires two fieldwork investigations: one in a physical environment and one in a human environment.
The Enquiry Sequence:
1. Identify a question or issue
2. Formulate a hypothesis (or research question)
3. Plan the methodology (what, where, how, when)
4. Collect primary and secondary data
5. Present the data using appropriate techniques
6. Analyse and interpret the data
7. Draw conclusions that answer the original question
8. Evaluate the enquiry process and findings
Physical Geography Fieldwork
Typical topics include: river characteristics (width, depth, velocity, bedload), coastal processes (erosion, longshore drift, sediment size), and weather/microclimate. Example: "How does the cross-profile of the River X change downstream?"
Human Geography Fieldwork
Typical topics include: urban land use changes, quality of the built environment, tourism impacts, retail sphere of influence, and environmental quality. Example: "Does environmental quality decrease from the CBD outwards in Town Y?"
❓ Formulating Questions and Hypotheses
Research Questions
Definition: A research question is an open-ended question that guides your enquiry. It should be specific, measurable, and linked to geographical theory.
Good research questions are:
- Specific: Not too broad - "How does urban quality of life vary in Bristol?" rather than "What is urban quality of life?"
- Locatable: Tied to a specific place that can be studied
- Measurable: Can be investigated using data collection methods
- Geographical: Connected to geographical concepts (place, space, process, scale)
Hypotheses
Definition: A hypothesis is a testable statement that predicts the expected outcome of the enquiry. It is often based on geographical theory and can be supported or rejected by evidence.
Example Hypotheses
Physical: "River velocity increases with distance downstream" - based on the Bradshaw Model which predicts that velocity, width, depth, and discharge all increase downstream as more tributaries join and the channel becomes more efficient.
Human: "Environmental quality decreases with distance from the CBD" - based on urban models which suggest that the inner city has older, more degraded housing and less investment than the city centre.
Coastal: "Sediment size decreases with distance along the beach in the direction of longshore drift" - based on the theory that attrition rounds and reduces sediment as it is transported.
Writing a Good Hypothesis:
A hypothesis must be: Testable (can be proven or disproven with data); Specific (clearly states what is expected); Linked to theory (based on geographical understanding); Directional (states the expected direction of change).
Format: "As [variable X] increases/decreases, [variable Y] will increase/decrease" or "[Variable Y] is higher/lower at [location A] compared to [location B]."
Null Hypothesis
A null hypothesis states there is no relationship or difference (e.g. "There is no significant relationship between distance downstream and river velocity"). Statistical tests like Spearman's Rank work on the null hypothesis - if the result is significant, you reject the null hypothesis.
📊 Selecting Appropriate Evidence
Key Concept: You must choose data collection methods that are appropriate for your hypothesis. The evidence should be sufficient, relevant, and reliable. Consider both primary data (collected by you) and secondary data (collected by others).
Matching Methods to Hypotheses
| Hypothesis | Primary Data Needed | Secondary Data Needed |
|---|---|---|
| River velocity increases downstream | Velocity measurements (flow meter), width, depth at multiple sites | OS map for site distances, Environment Agency flow data |
| Environmental quality decreases from the CBD | Environmental quality surveys, photo evidence, litter counts | Census data, deprivation indices, historic maps |
| Sediment size decreases along longshore drift | Sediment size measurements at intervals along the beach | Geology maps, coastal management maps, historic erosion data |
| Urban land use changes with distance from the CBD | Land use surveys, building age classification, rental prices | Google Earth imagery, census data, local authority plans |
Sample Size and Sampling Methods
The sample must be large enough to be representative but practical to collect:
- Too small: Results may not be representative; anomalies have too much influence
- Too large: Takes too long; may be impractical to collect
- Typical: 10-12 sites for a river study; 30-50 environmental quality surveys
📍 Identifying Suitable Locations
Choosing a Fieldwork Location
Key Factors: A good fieldwork location must be accessible, safe, relevant to the hypothesis, and representative of the geographical process being studied.
| Factor | Considerations |
|---|---|
| Accessibility | Can you reach the site safely? Is there road access or public transport? Is the terrain manageable for all group members? |
| Safety | Are there hazards (fast-flowing water, steep cliffs, busy roads)? Is the site away from dangerous areas? |
| Relevance | Does the site show the geographical process you are studying? Does it have enough variation to test your hypothesis? |
| Scale | Is the area manageable in the time available? Can you collect enough data at different points? |
| Representation | Is the site typical of the area, or is it unusual? Unusual sites may give misleading results |
| Permission | Do you need landowner consent? Are there access restrictions (nature reserves, private land)? |
Example: Choosing River Fieldwork Sites
For a river study testing the Bradshaw Model, you need sites from the source to the mouth. Choose 8-10 sites along the river's course, spaced roughly equally apart. Use an OS map to identify safe access points (footpaths, bridges, public rights of way). Avoid sites near weirs, deep water, or steep banks. Mark each site with a grid reference. Consider how far the group can walk in the time available.
Using Maps to Plan Locations
- Use OS maps to identify river courses, access points, and contours
- Use Google Earth/Street View for a virtual recce before visiting
- Mark sampling points on a map before fieldwork
- Record six-figure grid references for each site
⚠️ Risk Assessment
Definition: A risk assessment identifies potential hazards in the fieldwork environment, assesses the likelihood and severity of harm, and describes measures to reduce or eliminate risks.
| Environment | Hazard | Risk Level | Prevention/Mitigation |
|---|---|---|---|
| River | Drowning / deep water | High | Never enter water above knee height; wear buoyancy aids; work in pairs; avoid sites near weirs |
| River | Slippery banks | Medium | Wear appropriate footwear (wellingtons/gripping boots); avoid steep banks; use walking aids |
| River | Weil's disease (bacteria in water) | Medium | Cover cuts with waterproof plasters; wash hands before eating; avoid swallowing river water |
| Coastal | Rising tide / being cut off | High | Check tide times; identify escape routes; set a turnaround time; never work below cliffs |
| Coastal | Falling rocks / cliff collapse | High | Stay away from cliff base; wear hard hats near cliffs; check for warning signs |
| Urban | Traffic | Medium | Work on pavements; use pedestrian crossings; wear high-visibility vests; brief on road safety |
| Urban | Personal safety / harassment | Medium | Work in groups of 3+; stay in public areas; carry a mobile phone; have a meeting point |
| All | Extreme weather | Medium | Check forecast; wear appropriate clothing; have a wet-weather alternative plan; carry first aid kit |
Risk Assessment Structure:
1. Identify the hazard (what could cause harm?)
2. Assess who is at risk and how
3. Evaluate the risk level (high/medium/low)
4. Describe measures to eliminate or reduce the risk
5. Plan what to do if an incident occurs (emergency procedures)
General Safety Precautions
- Always work in groups (minimum pairs, ideally groups of 3-4)
- Carry a fully charged mobile phone
- Inform someone of your route and expected return time
- Carry a basic first aid kit
- Wear appropriate clothing and footwear for the conditions
- Have a clear emergency plan with contact numbers
- Check weather forecasts and have a contingency plan

✅ Answers
- A research question is an open-ended question that guides the enquiry (e.g. "How does environmental quality vary across the city?"). A hypothesis is a testable statement that predicts the expected outcome (e.g. "Environmental quality decreases with distance from the CBD"). A hypothesis is more specific and directional, allowing you to clearly support or reject it with evidence, whereas a research question invites broader exploration.
- "River velocity, width, and depth all increase with distance downstream from the source" - based on the Bradshaw Model which predicts these changes as the river is joined by more tributaries and the channel becomes more efficient through erosion and deposition processes.
- Factor 1: Accessibility - the site must be reachable safely by the group, with road or public transport access and manageable terrain. Factor 2: Relevance - the site must show the geographical process being studied (e.g. a river must have enough variation downstream to test the hypothesis). Factor 3: Safety - the site must be free from unacceptable hazards, such as fast-flowing water or unstable cliffs.
- Hazard 1: Deep water / drowning - minimise by never entering water above knee height, wearing buoyancy aids, working in pairs, and avoiding sites near weirs or waterfalls. Hazard 2: Slippery river banks - minimise by wearing appropriate footwear with good grip, avoiding steep or muddy banks, and using a walking pole for stability.
- Primary data is collected firsthand by the researcher, ensuring it is specific to the study location and up-to-date. Secondary data provides wider context, historical comparison, and larger datasets that would be impossible to collect personally (e.g. census data, Environment Agency records). Using both allows triangulation - checking that findings from one source are supported by another, increasing the reliability and validity of conclusions.

⚠️ Common Errors
Watch Out!
Students often write vague answers without specific geographical evidence. Wrong: Writing generalised statements like 'it causes problems' Correct: Using specific data and named examples, e.g. 'the 2010 Haiti earthquake killed over 200,000 people due to poor building quality'
Students often confuse causes and effects. Wrong: Mixing up what caused the event with what resulted from it Correct: Clearly separate causes (why it happened) from effects (what happened as a result)
Students often describe rather than evaluate. Wrong: Listing strategies without assessing their effectiveness Correct: Weighing up strengths and weaknesses of each approach and reaching a supported judgement
✍️ Model Answer
Full-Mark Response
6 marks: Explain the key factors affecting fieldwork: enquiry process.
Fieldwork: Enquiry Process involves multiple interconnected factors that geographers must understand. The key concepts include the processes that create and change fieldwork: enquiry process, the impacts on both people and environment, and the strategies used to manage associated challenges. For a comprehensive answer, specific case study evidence should be used throughout, with named examples and data to support each point. Geographical terminology should be used precisely, and the interrelationship between physical and human factors should be demonstrated. Top-level responses evaluate the relative importance of different factors and consider how the situation varies between locations.
