  • through fall
  • drainage basin
    • output
      • runoff
        • channel storage
      • leakage
        • ground water
      • evapotranspiration
        • controlled mainly by atmospheric conditions
        • evaporation requires a water-pressure gradient
          • humidity of the  atmosphere to be less than that of the ground
        • transpiration is water loss from plonts
        • potential evapotranspiration = ablity of the atmosphere to remove water from the surface assuming no limits on water supply
          • depends on: energy, wind, and water pressure gradient
        • channel storage
    • storage
      • vegitation
        • interception loss
        • stemflow
        • increased infiltration
        • through fall
        • interception
        • transpiration
        • evaporation
      • soil moisture
        • inflitration
        • zone of aeration = zone of transition> water is adsorbed held, or transmitted
        • soil moisture balance is linked to infiltration
        • different soils have different retention capacities and pore spaces
        • interflow
        • percolation
        • capillary rise
      • ground water
        • zone of saturation is the area where nearly all pore spaces are filled with water
        • Aquifers provide a great reservoir of water which regulates the hydrological cycle and maintains stream flow
        • base flow
        • capillary rise
        • percolation
        • recharge
      • surface
        • stem flow
        • throughfall
        • capillary rise
        • overland flow
        • infiltration
          • water soaks into or is absorbed by soil
          • capacity depends on soil texture, vegetation cover, existing soil moisture and time
    • input
      • precipitation
        • interception
        • channel precipitation
