the size of inputs, flows and stores in the water cycle
What happens to temperatures during WINTER?
May drop to below 0c
this causes water to freeze
This can reduce size of flows through drainage basins , while the store of frozen water grows
WHEN TEMPS INCREASE AGAIN flows through drainage basins can be much larger as the ice melts
what do most plants show?
Seasonal variation
What does vegetation do?
intercepts precipitation and slows its movement to the river channel
when is interception highest|?
when there is lots of vegetation and deciduous trees have their leaves
the more vegetation there is in a drainage basin...?
the more water is lost (through transpiration and evaporation directly from vegetation) before it reaches the river channel, reducing runoff and peak discharge
