HARDER — for designing fieldwork
H — A — R — D — E — R
| Letter | Stands for | What You Need to Include |
|---|---|---|
| H | Hypothesis | A specific, testable prediction with geographical reasoning |
| A | Aim | The broader enquiry question your hypothesis fits inside |
| R | Risk assessment | At least 3 hazards, their risks, and control measures |
| D | Data collection method | Which instrument, how used, why chosen |
| E | Equipment | Specific tools: tape measure, metre ruler, flow meter, clinometer, stopwatch, Powers Scale |
| R | Results presentation planned | Which graph type for each variable, with axes labelled |
TACT — for describing data patterns
T — A — C — T
| Letter | Stands for | Example in a river context |
|---|---|---|
| T | Trend | "Velocity generally increased from Site 1 to Site 7" |
| A | Anomaly | "Site 4 was anomalously slow at 0.12 m/s" |
| C | Comparison | "Site 7 velocity was 3.7× that at Site 1" |
| T | Terminology with figures | "Velocity rose from 0.18 m/s to 0.67 m/s across 700 m" |
The Bradshaw Model — DVWLGLG
To remember which variables increase downstream: "Drivers Velocity While Large Gorges Lose Gradient"
- D — Discharge increases
- V — Velocity increases
- W — Width increases
- L — Load roundness increases
- G — Gradient decreases (the exception — use this to remember the odd one out)
- And: load size decreases; depth increases
Remember the float method formula
V = D ÷ T (Velocity = Distance ÷ Time)
Same as speed in Physics — distance over time. 10 metres in 20 seconds = 0.5 m/s.
