This set goes deeper on rivers from physical geography. Each question supplies a profile, a graph or a case, and your answer must use it.
The four lessons build in order, and the practice set mixes them.
What does this set cover?
- Explaining erosion, transport and deposition along a supplied river profile says which process dominates at each stage.
- Connecting a river landform to the process evidence links what you see to how it formed.
- Interpreting a hydrograph without making a real flood prediction reads peaks and lag times.
- Evaluating a river management trade-off from a balanced classroom case weighs benefit against cost.
One short example: reading a hydrograph with care
An original hydrograph shows a river at 4 m³ per second before rain. After a storm it peaks at 28 m³ per second three hours after the rain peak. The rise is 28 − 4 = 24 m³ per second, and the delay is the lag time of 3 hours.
A safe statement is: “Flow rose by 24 m³ per second, peaking 3 hours after the heaviest rain, so the river responds fairly quickly.” An unsafe statement is: “This river will flood next month”. The graph records one past event, not the future.
| Reading | Safe statement |
|---|---|
| Peak flow | Flow peaked at 28 m³ per second |
| Lag time | The peak came 3 hours after the rain |
| Forecast | Not supported by one graph |
How do the parts connect?
The profile tells you where a river erodes, carries and deposits. Landforms record those processes, the hydrograph shows how the river responds to rain, and management choices try to change the response at a cost.
Who should start where?
- Name landforms but not the processes: start with the profile lesson.
- Know the processes but not the evidence: start with landform evidence.
- Freeze on hydrograph questions: start with the hydrograph lesson.
- Asked to recommend a scheme: start with the trade-off lesson.
