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^^)
