- River Basin: River Eden
- Background Info
- In north- west England between the mountains of the lake district and the Pennines
- It's source is in the Pennine Hills in south Cubria
- Upper Course
- Source is about 600m above sea level in an area of hard, resistant rock
- The valley is steep sided due to vertical erosion and the channel has a steep gradient
- River Channel is narrow and shallow
- Means discharge is low and velocity is low due to friction from the channel sides and bed
- The river carries large, angular stones
- Middle Course
- Made from sandstone, a soft, less-resistant rock which is easily eroded
- The valley sides become gentle slopes and the gradient of the channel is less steep
- River Channel also becomes wider and deeper
- River's sediment load is made up of smaller and more rounded rocks than it was in the upper course
- Lower Course
- The valley is very wide and flat
- By the time the Eden reaches Carlisle, it's only a few metres above sea level
- The river has a high velocity because there's very little friction from the channel's smooth sides
- River Channel is very wide and deep
- Climate and weather
- Temperature
- Mild winters, temperatures can be much colder
- Rainfall
- During periods of intense rainfall, the ground becomes saturated, can cause the river banks to slide or slump into the river channel
