  • Drainage Basin Hydrological Cycle
    • Vegetation Storage
      • This is where water is stored within plants and trees.
    • Channel Flow
      • Water flows in a river. This is the most efficient means of removing water from a drainage basin.
    • Transpiration
      • Water evaporates from inside vegetation and is returned to the atmosphere. Plants can control the rate of transpiration by opening and closing their stomata.
    • Throughflow
      • Water moves horizontally through the soil towards the rivers. Normally happens when soil is completely saturated.
    • Infiltration
      • The process by which water enters the soil. The rate can be affected by factors such as soil type, soil saturation and duration of rainfall.
    • Interception
      • Precipitation is trapped or stored temporarily on vegetation.
    • Base Flow
      • Water flows through rocks towards the river. The rock type can affect the rate of flow e.g. if the rock is permeable or not.
    • River run off
      • The total discharge of water from the drainage basin via its main river.
    • Water shed
      • An area of high land that divides two drainage basins.
    • Stem Flow
      • Precipitation runs down the stems of the plants or trunks of trees to the ground.
    • Perculation
      • Water drains down through rocks towards the water table.
    • Watertable
      • The upper surface of groundwater (all rocks and sediment below are saturated)
    • Channel Storage
      • Water is stored in a river. it is the amount of water stored in a river in a particular instant.
    • Ground Water Storage
      • Water is stored in permeable rocks below the surface of the ground
    • Overland flow
      • The movement of water over the surface of the ground to rivers.
