  • Factors affecting the shape of a hydrograph
    • human factors
      • interception
        • houses
          • gutters
            • drainage systems
              • quick flow
          • impermeable
        • trees
          • removing water
        • buildings
      • flood defenses
      • farming
        • animals
        • machinery
          • heavy
          • flattens land
        • soil
          • can be ploughed and air space created
    • physical factors
      • absorption rate
        • saturated
        • different surfaces
        • impermeable vs. permeable
      • rate of rain
        • quicker/slower
        • intensity
        • duration
      • amount of rainfall
        • volume
        • duration
        • intensity
        • previousrainfall
      • surface
        • steep = faster flow
        • flat = slower flow
        • seasons
          • leaves
          • windy
          • sunny
          • frozen
      • vegetation
        • use of water
