    • drainage basin
      • watershed
        • source
          • tributary
            • channel
              • mouth
                • sea
    • river profile
      • upper course
        • v-shaped valleys
        • interlocking spurs
        • waterfalls
          • gorges
      • middle course
        • waterfalls
          • gorges
        • meanders
          • ox-bow lake
      • lower course
        • meanders
          • ox-bow lake
        • estuaries
        • flood plains
          • levees
    • flooding
      • managing flooding
        • hard engineering
          • flood relief channels
          • embankments
          • dams /reservoirs
          • channel straightening
        • soft engineering
          • flood warnings and preparation
          • flood plain zoning
          • afforestation
          • river restoration
      • factors affecting discharge
        • geology
          • permeable rock reduces surface run-off by rapid infiltration
          • impermeable rock causes more run-off and streams by not letting water through
        • relief
          • the steeper the land the quicker water gets to the river
        • precipitation
          • heavy rain reaches river quickly because it doesn't soak in
        • land use
          • vegetation
            • helps prevent flooding as plants absorb water
              • rain forest absorbs 80% of rain
              • arable land absorbs 10% of rain
          • urbanisation
            • increase of flood risk as water can't pass through tarmac and concrete
          • dams and reservoirs
            • regulate and even out discharge reducing flood downstream
    • processes
      • erosion
        • hydrolic action
          • abrasion
            • attrition
              • solution
        • factors that effect erosion
          • rainfall
          • human factors
          • building concrete riverbanks
          • amount of bedload
          • gradient
