Fluxes are the ways that water moves between pools, such as evaporation, precipitation, discharge, recharge, or human use. Learn more about the water cycle and see the water cycle diagram on the USGS Water Science School website.
The area at the stream or lake to which the groundwater is flowing is a discharge area. What makes water flow from the recharge areas to the discharge areas? Recall that water is flowing in pores where there is friction, which means it takes work to move the water.
2 Αυγ 2014 · The discharge of a river (or stream) is the volume of water that flows past a point in the river’s course per second. The volume is measured in cubic metres (m 3) and it’s per second so the units of discharge are cubic metres a second or m 3 s-1.
3 Οκτ 2024 · The volume of water moving past a point in a river per given time is called the discharge – m³ /sec or cumecs. Discharge is calculated as Q = A x V. Q is discharged in cumecs. A is a cross-sectional area in m². V is the velocity in m/s There is a discharge relationship within drainage basins. The level of discharge is influenced by: Rate of ...
Example below shows changes in hydrograph caused by rapid urban development in the Mercer Creek Basin (WA) since 1977. Because of increase in impervious surfaces drainage area of the basin produces more discharge and consequently more strong floods.
18 Ιουν 2018 · The upper layer of the soil is the unsaturated zone, where water is present in varying amounts that change over time, but does not saturate the soil. Below this layer is the saturated zone, called groundwater, where liquid water is stored in all the pores, cracks, and spaces between rock particles.
