A rock layer that is permable to the flow of groundwater
1 of 18
Evapotranspiration
The water lost through combined effects of evaportation and transpiration
2 of 18
Surface runoff
When water flows over the surface of the ground
3 of 18
Infiltration
The downward movement of water that seeps into soil/porous rock
4 of 18
Interception
When plants prevent rainfall from directly reaching the ground
5 of 18
Water table
Top level of the ground water
6 of 18
Percolation
The movement of water through the soil or underlying porous rock. This water collects as groundwater.
7 of 18
Conventional rainfall
Mainly in the Tropics where the Sun rays are most concentrated. Water evaporates - then it rises - then it cools, condenses forms clouds and rains
8 of 18
Relief rainfall
Presence of mountains causes air to rise - then it cools, condenses forms clouds and rains.
9 of 18
Frontal rainfall
Hot and cold air meet in the mid-latitude zone which causes the hot air to rise and the cold air to sik. This hot air rises - then it cools, condenses forms clouds and rains

Source
Where the river starts
11 of 18
Confluence
The place where two rivers join
12 of 18
Channel
Body of water that flows deeper in the centre
13 of 18
Tributary
Any small river joining the main one
14 of 18
Drainage basin
The area of land drained by the river and all its tributaries. AKA catchment area
15 of 18
Mouth
The end of the river, where it meets the sea or a lake
16 of 18
Overland flow
When water flows over the surface of the ground
17 of 18
Throughflow
The movement of water with in the soil sideways, towards the river
