- RIVER EDEN
- Location and background
- Runs through North Cumbria
- Flooding is common in the basin and surrounding areas
- Physical factors that increase flood risk
- Faces south-westerly winds so climate is mild and wet
- Often has intense rainfall, records recorded there
- Basin is bordered by Lake district and Pennines
- These have hard impermeable rocks so water runs into the river channel
- Snowfall is common in Winter
- Melting adds lots of water to channel in short space of time
- Human activities that increase flood risk
- Carlisle is a built-up area, lots of development of the Eden's flood plain
- Lack of soil/vegetation means little infiltration of rainfall, so higher surface runoff
- Natural woodland cleared
- Increases surface runoff when it rains and water reaches the channel more quickly
- Parts of the valley have been drained to make them suitable for farming
- Drainage ditches means water flows rapidly to the channel
- Carlisle is a built-up area, lots of development of the Eden's flood plain
- 05/12/15 flood
- Antecedent conditions
- Soil already saturated and river discharge high
- Short lag time
- Rainwater quickly reached main channel
- Blockages
- Debris blocked smaller channels and bridges forcing water out of the channel
- Insufficient drainage
- Systems couldn't cope with volume of water and overflowed, making the flood worse
- Antecedent conditions
- Location and background
