Deposition is
another aspect that is not usually measured in water quality test, but
it has the ability to impact several other water quality issues. Basically,
deposition is the opposite of erosion. It is the act in which sediments
from the water are washed up onto the shore.
Like erosion,
geography is one of them major topographic features that affects it. However,
in contrast to erosion, deposition occurs where the stream finishes a turn.
The particles which have momentum from the water are carried in travel
to the far side of the river creating a smooth bank. These banks often
look sandy because of the numerous small sediments or grains-like sand.
