Percolation
When water travels from unsaturated ground into saturated ground.
1 of 16
Interception
When an object (building, tree) stops precipitation reaching the ground beneath.
2 of 16
Transpiration
Liquid water evaporating from vegetation.
3 of 16
River discharge
Eventually most rivers enter the sea and discharge the river's flow into the sea.
4 of 16
Groundwater flow
The movement of water through saturated ground.
5 of 16
Channel flow
Water that is travelling in rivers or streams.
6 of 16
Surface run-off (overland flow)
When water travels across the surface of the earth
7 of 16
Stem flow
When intercepted water then travels down the branches and trunks of vegetation.
8 of 16
Evaporation
Liquid water from surface stores and rivers turning into water vapour (gas).
9 of 16
Surface storage
Any water that is held on the surface of the earth e.g. lake or pond. Some surface stores like puddles may only be temporary.

Infiltration
When water travels from the surface of the earth into the ground beneath.
11 of 16
Groundwater storage
Water that is stored in saturated ground.
12 of 16
Throughflow
The movement of water through unsaturated ground.
13 of 16
Canopy drip
Intercepted water dripping off vegetation onto the ground.
14 of 16
Soil-moisture storage
Water that is stored below the surface in unsaturated ground.
15 of 16
Precipitation
Any moisture that falls from the sky e.g. rain or snow.
