Factors affecting changes in the water cycle

• Human characteristics

  • land-use change
  • farming practice
  • water abstraction
• Land use change:

  • urbanisation is the replacement of vegetated ground with impermeable concrete and tarmac. Water can't infiltrate the soil, which increases overland flow and increases the risk of flooding. Soil water and ground water are also reduced
• Land use change:

  • Deforestation can lead to surface runoff and soil erosion and reducing soil water stores
• Farming practices

  • Farmers can control the local water cycle through irrigation or land drainage. soils covered with plants have higher infiltration and soil water rates and therefore, reduce runoff
  • if desertification occurs, the capacity to retain water is much lower. This capacity is lost completely once the soil is sealed
• Do you watch horror station affects the water cycle as it decreases? Interception and increases discharge needing to higher chance of flooding
• Soil drainage removes accessibility from soil profileSoil drainage removes accessibility from soil profin sub surface drainage
• Advantages to soil drainage

  • Easy to grow crops
  • Improves aeration
• Disadvantage to soil drainage

  • Risk of flooding
  • Flash your hydrograph as it is an artificial system
