- Factors affecting river discharge
- Human Factors
- Building Urban areas around the river.
- Impermeable materials used as building and infrastructure materials
- Concrete
- Tarmac
- Infiltration
- Impermeable materials used as building and infrastructure materials
- Concrete
- Tarmac
- Infiltration will be less in urban areas, this increases surface run off for example.
- shorter lag time so river discharge increases massively very quickly
- Impermeable materials used as building and infrastructure materials
- Impermeable materials used as building and infrastructure materials
- Building on Flood plains
- Water not able to infiltrate back to the river easily
- Stopping natural levees and other processes.
- Not maintaining the river channel very well
- Man made sediment in the river will disrupt river flow
- Not enough dredging- this will reduce capacity and wetted load being carried
- Building Urban areas around the river.
- Physical Factors
- Heavy, Continuous rainfall
- Saturated land
- weathering
- Drainage basin characteristics
- Larger drainage basin more water to one river
- Tributaries
- Steep valleys, quicker lag time
- Gradient of the land
- Larger drainage basin more water to one river
- Heavy, Continuous rainfall
- Human Factors
