Erosion by Water

Water is the most efficient and effective agent for erosion. Erosion by water occurs in three different geologic settings:

Streams and Rivers – erosion commonly occurs along the bank of the stream. A stream is any size channelized body of running water (small creeks to giant rivers).
Coastlines – erosion that occurs on coastlines is due to the action of ocean currents, waves, and tides.
Underground– erosion that occurs at the sub-surface level due to underground water
