Water and Rivers II Definitions

HideShow resource information
Ground water
Is the water under the water table
1 of 23
Uptake
Is when the water is drawn in to the tree by its roots
2 of 23
Transperation
Is how trees get rid of the excess water
3 of 23
Evaporartion
The process when liquid turns to gas by heating
4 of 23
Stream flow
Is when the streams flow into the sea
5 of 23
Soil moisture
Is the water in the soil
6 of 23
Interflow
Is the water flowing towards the lowest point, the flow is between the though flow and the ground water flow
7 of 23
Overland flow / surface flow / run-off
Is when the water flows above the ground to lowest point
8 of 23
Though flow
Is when the water flows through the moist soil to get to the lowest point
9 of 23
Base flow
Is the normal height of the river when there has been no rainfall, the river drains the water stores from the groundwater flow, inter flow and through flow
10 of 23
Lag time
Is the difference between the highest rain point and the highest discharge levels
11 of 23
Discharge
Is the excess water the river does not want
12 of 23
Thalweg
Is the fastest pint int he rive (the line of fastest flow)
13 of 23
Abrasion
is when the river uses it load to erode the channel
14 of 23
Hydraulic action
Is then the water compresses the air in gaps of the side of the river and the air expands (causing a explosion effect) causing the bank to break down
15 of 23
Attrition
Is when load collides with other pieces of load causing them to chip and break down
16 of 23
Solution
Is when the rock dissolves in to the river
17 of 23
Traction
The rolling of heavy load along the river bed due to lack of energy
18 of 23
Saltation
When the load is picked up and dropped over and over again along the river bed
19 of 23
Suspention
Is when small particles hand in the water because the river has enough energy to carry it
20 of 23
Solution
Is then the rock that the river has dissolved is being transported
21 of 23
Erosion
Break down and removal or rock by a third party
22 of 23
Weathering
Breakdown where it stands
