  • Factors affecting Discharge
    • Physical
      • Weather
        • Snow - melt, frozen ground no infiltration
        • Percipitation - heavy rainfall, ground too saturated
        • Temperature - evapotranspiration (reduce discharge)
      • Vegetation - more trees, less infiltration
      • Porus soil type/ permeable rock - slow
      • Impermeable rock - faster
    • Human
      • Urbanisation
        • Permeable structures, artificial drainage, machinery
      • Land use
        • Dams, agriculture
      • Deforestation
