A watershed is an area of land that collects water and then discharges it into streams, lakes, or oceans at the watershed outlet.

Watersheds can vary in size from a small town, to a state, or the entire country

The western sides leads all rainwater to the Pacific Ocean

The eastern side leads all rainwater to the Atlantic Ocean

Watershed Characterstics

- Land Use: Forested/Arid

- Soil Type: Sandy/Clayey

- Storm Intensity: Long time/Short time

- Vegetation: Corn/Soybean/Veggies

- Weather: Precipitation/Heat

- Topography: Flat/Hilly

These factors can affect the amount of runoff in a watershed

​​Peak: Max flow rate of runoff in one storm event

Volume Under Curve: Total amount of runoff

Curve Number

​The Curve Number (CN) is the amount of potential runoff of a watershed

CN = 100 : Max Runoff

CN = 0 : No Runoff

CN based off a predetermined table of characteristics

Urban Landscapes will generally have a higher CN because there are less plants and soil available to retain water
