River fieldwork: test a geographical idea
Fieldwork turns a landscape into evidence. You will design a fair enquiry to test how a river changes downstream, then decide how confidently the data supports the idea.

Start with a testable question
A focused enquiry might ask: ‘Does channel velocity increase downstream?’ Predict the pattern using river theory, identify an upstream and downstream site, and keep the measuring method consistent so location is the main variable changing.

Collect reliable data
Measure width with a tape and depth at equal intervals with a metre ruler. Estimate velocity by timing a float over a measured distance, repeating at least three times and calculating a mean. Work from the bank where possible, check weather and flow conditions, and follow an adult-led risk assessment.

Present and analyse
A scatter graph can compare distance downstream with velocity or cross-sectional area. Describe the overall trend, quote values, identify anomalies and explain them. Recent rain, a bridge or a shallow riffle may create results that do not fit the pattern.

Reach a careful conclusion
State whether the evidence supports the prediction, then evaluate sample size, measurement error and site choice. A strong conclusion does not claim more than the data shows; it suggests a precise improvement or a new location to test.
