The Drainage Basin Flashcards
Name the input of the drainage basin cycle.
The input of the drainage basin cycle is PRECIPITATION.
Name the stores of precipitation in the drainage basin cycle.
Interception by vegetation, soil, groundwater
Name transfers in the drainage basin cycle.
Transfers in the drainage basin cycle are: SURFACE RUN-OFF, INFILTRATION, THROUGHFLOW, PERCOLATION and GROUNDWATER FLOW.
Name the output of the drainage basin cycle.
The output of the drainage basin cycle is RIVER DISCHARGE.
What is PRECIPITATION?
PRECIPITATION is water which enters the drainage basin cycle, in any form.
What is INTERCEPTION BY VEGETATION?
INTERCEPTION BY VEGETATION is the process by which water may be caught on the leaves of plants as it falls.
SURFACE RUN-OFF occurs when…
SURFACE RUN-OFF occurs when water hits an impermeable surface, which then flows over the surface into the nearest river.
INFILTRATION is when…
INFILTRATION is when water seeps into the soil.
The movement of water from the surface into the soil
THROUGHFLOW is when…
THROUGHFLOW is when water in the soil is pulled downwards by gravity.
PERCOLATION is…
PERCOLATION is water moving from the soil into the bedrock.
GROUNDWATER FLOW is…
GROUNDWATER FLOW is water moving through the bedrock.
RIVER DISCHARGE is…
RIVER DISCHARGE is the volume of water flowing through a river channel.
Define WATERSHED
The WATERSHED is the boundary of a drainage basin.
What is the SOURCE of a river?
The SOURCE of a river is where a river begins, usually in upland area.
What is a TRIBUTARY?
A TRIBUTARY is a stream or small river that flows into the big river.
