watershed management

• Watershed: drainage basin through stream system
• drainage basin: watershed that collects and discharges streamflow through an outlet
• watershed management: process of organizing land use on watershed to provide goods and services without affecting the soil and water
• water in watershed: Properties: state of water, change in state of water in environment, change of state of water in water cycle
• evaporation: liquid to vapor
• condensation: vapor to liquid
• sublimation: solid to vapor
• I-O=S; P-gwi-q-et-gwo=s
• what is a main driver in watershed management?

  weather
• weather problems: fires, drinking water, flooding, agriculture, range
• what is the most important and expensive part of water budget?

  precipitation
• why is precipitation important?

  want to know what causes precipitation and the amount of it
• Examples of precip?

  rain,snow,sleet,hail,fog,dew
• What are primary drivers in weather and precip?

  temp and pressure
• temp?

  radiation- gives off energy; conduction-direction transfer of heat; convection- through moving gas/liquid
• atmospheric pressure?


  pressure of air in atmosphere; 10,000 kg/sq m at sea level; elevation increases, pressure decreases
