1.5 Capture the Flow Flashcards
What affects the water flow through a drainage basin?
Temp, rainfall, light, climate and time of year (season)
What is cloud seeding?
Attempt to change the type of precipitation by dispersing substances in the air
How does urbanisation disrupt the drainage basin?
Creates impermeable surfaces and reduces infiltration
How does dam construction disrupt the drainage basin?
increases water stores and reduces downstream discharge
How does groundwater abstraction affect the drainage basin?
Because humans extract it much quicker than it can replenish itself
What are human schemes designed to actually do?
Control river processes such as seasonal flooding
Why is deforestation of the Amazonia bad?
It disrupts the input/output balance
What is irrigation?
Taking water from underground stores
What are 4 main human activities that affect the drainage basin?
abstraction, cloud seeding, irrigation, urbanisation
How is evaporation affected by human activities?
Deforestation and dams
