Question

what do you mean by latersal erosion ofna river?

Answer 1

Lateral erosion is the process by which a stream over time sweeps back and forth after initially incising, and changes a V-shaped into a U-shaped one. By this process, a floodplain is created which increases the stream valley’s capacity to carry floodwaters and limit future downcutting.

Answer 2

A concurrent process called lateral erosion refers to the widening of a stream channel or valley. When a stream is high above its base level, downcutting will take place faster than lateral erosion; but as the level of the stream approaches its base level, the rate of lateral erosion increases
