Influences of Climate on Geomorphic Processes

Being on the UK's north-west coast, Cumbria is directly exposed to the dominant south-westerly winds. Because of this, Cumbria's climate is wet and mild.

Temperature

Temperature

  • Temperatures can get very low on the high ground near the Eden's source. In winter, this high ground freezes, leading to freeze-thaw weathering (particularly in the upper course).
  • Weathering weakens the rock in the valley, increasing the likelihood of mass movement.
  • Material from mass movement events increases the amount of material or sediment being carried by the river, leading to increased erosion by abrasion.
Rainfall

Rainfall

  • Intense precipitation can cause the ground and soil by the River Eden to get saturated. The reduced stability of saturated ground makes landslides more likely.
  • Heavy rain can rapidly enter water channels in the basin from V-shaped valleys. Rapid surface runoff can lead to rapid increases in channel volume.
  • More material is transported when the channel is more full. Increased transportation means increased erosion by abrasion.
