the drainage basin

state the paths/routes of the drainage basin

ponds puddles flowers plants rivers ocean air trees leaves lakes

started the definition of evapotranspiration

water vapour is released through the stomata (pores) in the leaves

started the definition of interception

water is stored on leaves and branches of vegetation

started the definition of throughflow

water flows horizontally through the soil into the river

started the definition of percolation

the vertical movement of water from the soil into the bedrock

started the definition of infiltration

the movement of water from the surface into the soil

started the definition of groundwater flow

water flows horizontally through the rock into the river

started the definition of evaporation

water turns from water droplets into water vapour

started the definition of surface runoff/overland flow

water flows horizontally over the land into the river

what are the inputs of the drainage basin ?

precipitation

what are the stores of the drainage basin ?

groundwater storage interception soil water storage surface water storage

what are the transfers processes of the drainage basin ?

surface runoff/overland flow throughflow infiltration percolation groundwater flow

what are the outputs of the drainage basin ?

river discharge evaporation evapotranspiration

state the definition of saturated soils

soils that are full of water. they may also be described as being waterlogged. soils can become fully saturated during a heavy rainfall event. this limits infiltration, increases surface runoff and can cause a rivers discharge to increase

whats a closed system and an example ?

a closed system means there’s no additions and no losses, example hydrological cycle

whats a open system and an example ?

an open system means there’s additions and losses, example drainage basin system

what are the features of the drainage basin ?

source mouth watershed meander tributary and confluence

what’s the source ?

where the river begins usually on high ground

what’s the mouth ?

where the river meets the sea or a lake

what’s the watershed ?

the boundary separator one drainage basin from another - usually a ridge of high ground

what’s a meander ?

a bend in a river formed by erosion

what’s a tributary ?

small river joining the main river

what’s the confluence ?

the meeting point of 2 rivers
