- Human Causes
- Urbanisation
- More people in towns and cities
- Floodplain development/built upon
- The impermeable surfaces increase overlandflow, and decrease infiltration meaning water gets to the channel quicker
- Deforestation
- Greater risk of soil erosion and increase sediment in the river
- Lack of interception and storage of water
- and other changes in vegetation cover e.g agriculture
- River Management
- Embankments
- Dams
- Artificial levees and channels, increasing the flood risk elsewhere
- Climate Change
- Enhanced Greenhouse effect increasing the sea temperature
- increases evaporation leading to more water in the atmosphere, increasing frequency and severity of extreame events
- More snow melt water
- Urbanisation
