1

Hydrology

Study of water

2

Hydrological cycle

Movement of water between air, land and sea

3

Precipiration

Includes all forms of rainfall, snow, frost, hail and dew.

4

Interception

Precipitation collected and stored by vegetation

5

Overland flow

Water that flows over the land's surface

6

Infiltration

Water that seeps into the ground

7

Evaporation

Water from the ground or lake that changes into a gas

8

Transpiration

Water loss from vegetation to the atmosphere

9

Evapotranspiration

Combined losses of evaporation and transpiration

10

Drainage basin

Area of the land drained by a river system

11

Interception

Precipitation that is collected and stored by vegetation

12

Throughfall

Water flowing off wet leaves onto the ground

13

Stemflow

Water flowing down the trunks of trees and stems of grasses and shrubs

14

Percolation

Movement of water down into the groundwater zone

15

Throughflow

Water flowing through the soil down to the groundwater zone

16

Baseflow

Movement of water through rock. Slowest form of water movement (Due to it there's constant water flow even on low rainfall season)

17

Water Table

Upper layer of permanently saturated pore spaces in the groundwater zone

18

Groundwater

Water stored underground in a permeable rock. e.g Chalk.

19

Aquifers

Layers of rock filled with groundwater

20

Recharge

Topping up of groundwater levels following abstraction

21

Open system

It allows the movement of energy and matter across its boundaries

22

Wilting point

Range of moisture content in which permanent wilting of plants occur

23

Percolines

Lines of concentrated water flow between soil horizons
