1.1 Stores & Flows

Question 1

What are the human impacts of stores & flows?

Answer 1

Urbanisation/Landuse
Deforestation
Dams
Water Abstraction

Question 2

How does deforestation effect stores & flows

Answer 2

Deforestation - decreased stemflow + throughflow - therefore decrease infiltration

Yanna China - 60s mass deforestation due to urban growth - flood in 98 due to this

Question 3

How does Urbanisation effect stores & flows

Answer 3

decrease infiltration due to impermeable materials - decrease overland flow due to storm drains = higher peak discharge

Question 4

How does Dams effect stores & flows

Answer 4

decrease river discharge - increase evaporation
Lake Nasser 1/3 loss evaporation

Question 5

How does water abstraction effect stores & flows

Answer 5

Reduces baseflow - can lead to rivers drying up

Malta cannot any water for drinking due salination

Question 6

What are the climatic impacts of stores & flows?

Answer 6

Precipitation
Temperature
Humidity

Question 7

How does precipitation effect stores & flows

Answer 7

Size
Intensity
Duration

All increase surface runoff

Question 8

How does temperature & humidity effect stores & flows

Answer 8

Higher of both = more evaptranspiration
Claussius Clapyron

Question 9

What are the physical factors of stores & flows?

Answer 9

Vegetation - increase vegetation = increase infiltration due pipes & perolines - roots
Soil Type - Course vs Fine // Granular
Rock Type - Porous vs Permeable
