precipitation
water in any form which falls from the atmosphere to the surface of the earth
1 of 18
evaporation
process by which liquid water transforms into vapour
2 of 18
transpiration
process by which water is lost from a plant through the stoma in its leaves
3 of 18
infiltration
passage of water into soil. Water drawn into soil by gravity and capillary attraction
4 of 18
percolation
downward vertical movement of water within a soil. Water enters groundwater
5 of 18
soil moisture storage
water found in soil
6 of 18
base flow / ground water flow
part of river's discharge which is produced by groundwater slowly seeping into river bed
7 of 18
ground water storage
water that collects underground in pore spaces of soil and rock. When it fills all pores, the rock is sad to be saturated
8 of 18
surface storage
total volume of water held on earth's surface in lakes, ponds and puddles
9 of 18
surface run-off / overland flow
movement of water over land surface, usually when ground is saturated or frozen or when precipitation is too intense for infiltration to occur
10 of 18
through flow
water which moves down through subsoil. Particularly effective where further downward percolation or is prevented by underlying impermeable rock
11 of 18
stem flow
water which runs down from stems and branches of plants during and after rainstorm in order to reach ground surface. Takes place after interception occurs
12 of 18
through flow / drip/ dripfall
water drips on leaves during and after rainstorm. When leaf has exceeded capacity to hold water, it falls to the ground surface
13 of 18
permeable
rock or surface which allows water to pass through and into it
14 of 18
impermeable
rock or surface which does not allow water to pass through or into it
15 of 18
porous
allows water to pass through, making use of space between pores. Rock are porous since they allow water to penetrate gaps between rock particles
16 of 18
pervious
allows water to pass through due to cracks or defects.
17 of 18
evapotranspiration
total of both transpiration and evaporation
18 of 18
