Area that supplies a river with its supply of water, this includes water found below the water table as well as soil water and any surface flow.
The total output of water from the drainage basin directly back into the atmosphere from evaporation and transpiration
The process by which liquid water changes to a gas. This requires energy, provided by the sun and aided by wind.
The slow movement of water through underlying rocks
The downward movement of water from the surface into the soil
The tendency of water to flow horizontally across land surfaces when rainfall has exceeded the infiltration capacity of the soil and all surface stores are full
The precipitation that falls on the vegetation surfaces or human-made cover and is temporarily stored on these surfaces
The movement of water down slope through the subsoil under the influence of gravity
All of the water that enters a river channel and eventually flows out of the drainage basin
The downward movement of water within the rock under the soil surface. Rates vary depending on rock.
The balance between inputs and outputs in a drainage basin
The proportion of precipitation intercepted by the canopy that reaches the ground by flowing down stems, stalks or tree bole.
The amount of water stored in the soil.
Most plants remove water from the soil and store it in the structure of a plant
Is exceeded when rainfall intensity is greater than the infiltration rate
Transfers of water within a river or stream
