River Eden case study

Where is it?

• North west England between the Lake District and Pennines

Landforms

• V-shaped valleys - ^^600 metres^^ above sea level
• Hell Force Waterfall - hard rock (^^limestone^^), soft rock (^^sandstone^^)
• Meanders near ^^Salkeld^^
• Oxbow lake near ^^Briggle Beck^^
• ^^Carlisle^^ is built on the floodplain

Processes

• Regular freezing in the winter near the source, leading to ^^freeze thaw weathering^^
• Intense rainfall can lead to ^^landslides^^, so more material in the river
• ^^High river volumes^^ can increase geomorphic processes
• ^^Limestone^^ is vulnerable to ^^chemical weathering^^
• West of River Eden there is ^^impermeable rock^^, making ^^flooding more likely^^
• ^^Sandstone^^ is prevalent in in middle+lower courses, ^^increasing erosion^^

Human activity

• ^^10km of flood walls + embankments^^ along river
• ^^Castle Carrow Beck^^ (south west of Carlisle)has been ^^dammed to create a reservoir^^
• Near ^^Dalston^^ (south of Carlisle) ^^1,000 trees^^ have been planted
• Restoration of the river from its ^^previously straightened state^^ (e.g ^^artificial meanders created south west of Appleby - slows river flow^^)
