water cycle

• Baseflow


  Water flowing out from groundwater storage into a river or stream.
• Channel Storage


  Water flowing in a river or stream channel.
• Evaporation


  Water flowing in a river or stream channel.

  Evaporation: Water being returned to the atmosphere by changing state from a

  liquid to a vapour. Caused by heating of surface water, such as lakes and the

  ocean.
• Evapotranspiration


  The combined processes of evaporation and transpiration.
• Groundwater storage


  Water stored within rocks underground. The rocks are saturated with water in this area. The top of this saturated zone of groundwater

  is known as the water table.
• Infiltration


  Water soaking into the ground through the soil surface.
• Interception


  Precipitation is caught and stored on the surface of vegetation,

  especially leaves.
• Stem Flow


  Precipitation that has been intercepted by vegetation, then passes down the branches, stems and drips off the leaves to the ground.
• Overland flow/surface runoff


  Water flowing as a sheet or little rivulets over

  the ground surface.
• Percolation


  Water moving downwards from the soil into the rocks beneath.
• Permeability


  How connected the pores are within rock or soils, a higher permeability allows water to move through the rock or soil easier.
• Plant uptake


  Water being taken up from the soil into vegetation via roots.
• Porous


  The ability to hold water in pores
• Precipitation


  Water falling from the sky and deposited on Earth's surface in various forms e.g., rain, snow, sleet and hail.
• recharge


  Refilling of a zone of saturation following a period of draw down
• Soil water


  Water held by the soil either on or between soil particles
• Springs


  Natural discharge point of water at the surface of the ground from beneath the surface.
• Surface water


  Water stored on the ground surface in pools, puddles, ponds and lakes.
• Throughflow


  Water flowing down slope through the soil, almost parallel to the surtace.
• Transpiration


  Water vapour returned to the atmosphere by plants through stomata in their leaves.
• Vegetation water


  Water stored within the tissues of plants.
• Water table


  The layer separating saturated bedrock below from unsaturated bedrock below. The water table follows the shape of the topography goes up and down due to the inputs and outputs of the hydrological cycle.
