Drainage Basins (Grade 12 NSC Matric Geography): Flashcards

Smooth water movement through even channels; highly efficient

Water through rough channels; creates eddies; less efficient

Area of land drained by a river system and its tributaries

Where river begins; often in mountainous/highland regions

Smaller streams/rivers that flow into the main river

Boundary line separating one drainage basin from another

Measure of how many streams/tributaries exist in a basin

Creates low drainage density (fewer surface streams)

Creates high drainage density (more streams/tributaries)

Gentle slopes, dense vegetation, soft rain, permeable soil
