river environments - drainage basin Flashcards
inputs of a drainage basin
energy from sun, precipitation,
output of a drainage basin
river’s discharge, water that has been evaporated
three types of drainage basins
- those that collect and deliver water to the sea
- those that are part of a much larger drainage basin
- those that lead to ‘inland’ seas or lakes
what is a drainage basin?
an area of land that is drained by a river and its tributaries
inputs
how water is introduced into the drainage Bain system, this is known as precipitation
stores
how water is stored or held for a period of time within the drainage basin system, surface storage (lakes), soil moisture
transfers
a process or flow of water from one place to another in the drainage basin system, surface run off, infiltration, percolation
outputs
how the water is released either back to the sea or back into the atmosphere, river discharge, evaporation, transpiration
