Local changes in the magnitude of stores

Question 1

Extreme weather events

Answer 1

Droughts cause a reduction in water stores in rivers and lakes. Vegetation dies back affects interception and infiltration.
Soils dry out causing reduced soil water store.

Question 2

Precipitation

Answer 2

Summer: less rainfall, more frequent storms
Winter: Greater quantities of rainfall, more snow

Question 3

Vegetation

Answer 3

Summer: grows rapidly increases interception and transpiration
Winter: Dies reducing interceptiona dn transpiration

Question 4

Evaporation

Answer 4

Summer: high temperatures encourage more evaporation (more moisture)
Winter: Lower temperatures reduce evaporation

Question 5

Soil water

Answer 5

Summer: dry soils encourage infiltration, hard soil encourages overland flow
Winter: More saturated, overland flow

Question 6

River channel flow

Answer 6

Summer: low flow
Winter: high flow

Question 7

Farming practices

Answer 7

Control local water cycle by irrigation/land drainage.
Less runoff in soil

Question 8

Peatland drainage

Answer 8

Lowered water table, changing rates of infiltration and evaporation
Important carbon stores

Question 9

Land use change

Answer 9

Urbanisation- impermeable surfaces. Water cannot infiltrate the soil=more runoff
