Understanding River Channel Widening: Lateral Erosion
Lateral Erosion: How Rivers Carve Their Channels
Learn about the causes, effects, and prevention of lateral erosion in river systems.
Lateral erosion is a key process shaping river channels. This page explains what causes it, its impacts, and how it can be mitigated.
Causes of Lateral Erosion
The force of a river's current against its banks, particularly in the middle and lower courses, is the primary cause. Impact from large objects can also contribute.
Effects of Lateral Erosion
Channel widening, loss of land, increased flood risk, and damage to infrastructure are significant consequences.
