1.1 Drainage Basins and Rivers
Explain water-cycle and drainage-basin systems, river processes and landforms, and sustainable or non-sustainable relationships between rivers and people.
How to study WJEC GCSE Geography
Move from place and process to mapped or numerical evidence, explain inter-relationships across scale, and finish with a supported geographical judgement.
Core concepts
Concept 1
1.1.1 The global hydrological cycle: closed system, stores and flows
Exam cue: Confirm the current WJEC unit, numbered content area, geographical scale, named context and assessment form before selecting evidence.
Concept 2
1.1.2 The drainage basin system: open system, inputs, transfers, stores, outputs and seasonal variation
Exam cue: Treat the drainage basin as a connected system: trace a change through stores, transfers, discharge, process, landform and human consequence.
Concept 3
1.1.3 Drainage basin features and weathering, erosion, transportation and deposition
Exam cue: Use mapped, numerical, graphical, fieldwork or source evidence to explain process and inter-relationship, then make a scale- and context-aware judgement.
Concept 4
1.1.4 Long and cross profiles plus discharge, geology, gradient and velocity
Concept 5
1.1.5 Waterfalls, plunge pools, gorges, floodplains, meanders and oxbow lakes with a local or Welsh river valley
Concept 6
1.1.6 River use, flooding, erosion, engineering and sustainable management
Risk pitfalls and guardrails
Describing a river feature without explaining the interacting processes or locating the required local or Welsh example.
Guardrail: Use the number and type of named contexts required by the specification and connect each fact directly to process or judgement.
Importing the legacy WJEC 3110 structure, an Eduqas option pattern or an England 9-1 grading convention.
Guardrail: Do not import legacy or Eduqas structures, invent an option split or make claims that exceed the named evidence and assessment controls.
Treating an annual Unit 2 theme, local example or Unit 4 Resource Pack as a separate qualification or a compulsory option for every learner.
Guardrail: Use one centre-selected theme valid for the submission year; do not split themes into separate qualifications or replace the live Assessment Pack with guidance examples.
Memory anchors
hydrological cycle
The global closed system of water stores and flows.
drainage basin
The area drained by a river and its tributaries.
watershed
The high-land boundary separating drainage basins.
discharge
The volume of water passing a point in a river per unit time.
meander
A river bend developed through linked erosion and deposition.
soft engineering
Management that works with natural river processes and environments.
Checkpoint rule
Do the check-up only after you can summarize each concept in one sentence and identify one dangerous pitfall from memory.
Knowledge Check (after reading)
