Water Cycle ~ the movement of H2O through the hydrosphere, and other spheres.
H2O can only be added to an area by runoff, by infiltration and by precipitation.

Water Cycle ~ the movement of H2O through the hydrosphere, and other spheres.
H2O can only be removed from an area by runoff, by infiltration and by evaporation.

Water Cycle ~ the movement of H2O through the hydrosphere, and other spheres.
H2O can only be removed from an area by runoff, by infiltration and by evaporation.
Transpiration (plants) and evaporation (from water areas) is called EVAPOTRANSPIRATION

Water Cycle ~ the movement of H2O through the hydrosphere
Will the water budget ever be in balance locally?
![Page 9: Rivers and Streams](https://reader036.vdocuments.net/reader036/viewer/2022062408/56813820550346895d9fd035/html5/thumbnails/9.jpg)
Water Cycle ~ the movement of H2O through the hydrosphere
Will the water budget ever be in balance locally?
NO!! It is usually raining, or transpiring/evaporating, but not both in equal amounts at the same time.

Water Cycle ~ the movement of H2O through the hydrosphere
Will the water budget ever be in balance worldwide?
![Page 11: Rivers and Streams](https://reader036.vdocuments.net/reader036/viewer/2022062408/56813820550346895d9fd035/html5/thumbnails/11.jpg)
Water Cycle ~ the movement of H2O through the hydrosphere
Will the water budget ever be in balance worldwide?
Yes!! Otherwise the air would “dry out”, or get “misty” everywhere.

Water Cycle ~ the movement of H2O through the hydrosphere
Where will most of the water evaporate from?
![Page 13: Rivers and Streams](https://reader036.vdocuments.net/reader036/viewer/2022062408/56813820550346895d9fd035/html5/thumbnails/13.jpg)
Water Cycle ~ the movement of H2O through the hydrosphere
Where will most of the water evaporate from?
THE OCEAN, since ¾ of Earth is covered by it!!

Water Cycle is water constantly moving among the oceans, the atmosphere, the solid Earth, and the biosphere. This unending circulation of Earth’s water supply is the water cycle.

Recycling of water, almost does not exist. 90% of all water used by industry and cities runs back to the Ocean.

Factors that determine rates of water runoff
Soil composition. Loose soil with heavy rains, with little soil to hold it in place will often cause mud slides.
![Page 33: Rivers and Streams](https://reader036.vdocuments.net/reader036/viewer/2022062408/56813820550346895d9fd035/html5/thumbnails/33.jpg)
Porosity is the amount of space in the pores of the soil, in this case a poorly sorted specimen.

Permeability is how fast water will flow through something.

Stream Load ~ All the materials that the water in a stream carries.
Solution ~ Dissolved minerals.
Suspension ~ Particles held up by the moving water.
Bed load ~ Particles bounced along the bottom of the stream.

Stream Load ~ All the materials that the water in a stream carries.
Solution ~ Dissolved minerals.
a. Usually salts, or salt forming ions.
b. Counted in parts per million (ppm).

Stream Velocity and Carrying Capacity
Stream Velocity based on how fast water flows.
Carrying capacity is how much of a stream load a stream can….carry.
Based largely on discharge.
m3/s = meters x meters x meters ÷ seconds

Floodplains
Flood ~ too much water in one place at one time.
Floodplain ~ where all that water goes
a. Nice an flat
b. Fertile soils
c. Sometimes covered with water
i 10 year flood
ii 50 year flood
iii 100 year flood
iv 500 year flood
