water cycle

• ground water flow


  water flowing slowly through rocks towards the sea
• river channel


  a landform on which a relatively narrow body of water is situated
• evaporation


  the process that changes liquid water to gaseous water (water vapor)
• Rivers can be affected by natural processes such as erosion, deposition, flooding, and drought, as well as human activities like dam construction, deforestation, and pollution.
• surface runoff


   the unconfined flow of water over the ground surface
• surface storage


  Any water that is held on the surface of the earth 
• transipiration

  the process of water movement through a plant and its evaporation from aerial parts, such as leaves, stems and flowers
• interception


  precipitation that does not reach the soil, but is instead intercepted by the leaves, branches of plants and the forest floor
• precipitation


  any liquid or frozen water that forms in the atmosphere and falls back to the earth
• infiltration

  The downward movement of water from the surface into the soil
• through flow

  Water flows downhill within the soil.
• percolation


  The downward movement of water from the soil into the rock beneath
• soil moisture


  the total amount of water, including the water vapor, in an unsaturated soil
• ground water


   water that exists underground in saturated zones beneath the land surface
• inputs


   How water is introduced into the drainage basin system. This is known as precipitation
• transfers


   A process or flow of water from one place to another in the drainage basin system - surface run-off/overland flow,infiltration, percolation, through-flow, groundwater flow
• outputs


  How the water is released either back to the sea or back into the atmosphere - river discharge, evapotranspiration
• peak rainfall


  the hightest amount of rainfall
• peak discharge


  hightest discharge
• lagtime


  time difference between peak rainfall and peak discharge
• base flow


  the normal flow of the river as groundwater moves into the river channel
• storm flow


  resulting from increased rainfall involving both surface and through flow
• rising limb


  shows how the flow(discharge) of the river is rising
• falling limb


  shows the flow(discharge) of the river decreasing
• drainage basin


  are of land where water converges to a simple point
• discharge


  the volume of water carried by the river
