- 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
- runoff
- 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
- vegitation
- input
- precipitation
- interception
- channel precipitation
- channel storage
- overland flow
- interflow
- floods
- recharge
- channel storage
- precipitation
- output
- in
- out
