- Factors increasing flood risk
- human factors (land use)
- urbanisation
- impermeable surfaces, e.g. tarmac roads, maean water flows quickly into drains, sewers and river channels
- deforestation
- when trees are removed, much of the water which had been evaporated from leaves or stored on leaves and branches flows rapidly into river channels
- agriculture
- exposed soil can lead to increased surface runoff
- urbanisation
- physical factors
- precipitation
- torrential rainstorms and/or prolonged periods of rain can lead to flooding
- geology
- impermeable rocks don't allow water to pass through, so it flows overland into river channels
- relief
- steep slopes mean water flows quickly into river channels
- precipitation
- human factors (land use)
