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.

Part of your national curriculum

Part 3 of 14

Learn

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.

Learn

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.

Learn

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.

Learn

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.

This is the part you'd do in your book at school. Pick the pieces below, write here or on paper, and photograph anything you draw or work out.

Case study

Flooding on the River Calder

The town of Harbrook sits where a steep valley opens onto a flat floodplain. In December 2015, 120 mm of rain fell in 36 hours onto ground that was already saturated. The river rose 2.4 m in five hours, and 380 homes and 54 businesses flooded. Two roads and the railway closed for eleven days.

Geographers pointed to physical causes — steep slopes, impermeable rock, heavy rainfall — and human causes: moorland drained upstream, new housing built on the floodplain, and drains designed for smaller storms.

Since then the town has planted 40 hectares of woodland upstream, built leaky dams in small streams, and raised flood walls to 1.8 m. In the storm of 2020 the peak river level was 0.3 m lower and 40 homes flooded, not 380.

Written for Good Learning Co.

Reading questions

  1. List two physical and two human causes of the 2015 flood.
  2. Explain how planting woodland upstream lowers the river's peak level.
  3. Using the figures, judge how successful the scheme has been. Quote data in your answer.
