2. Transportation
• The river picks up sediment and
carries it downstream in different
ways.
• Transportation of material in a river begins
when friction is overcome. Material that
has been loosened by erosion may be then
transported along the river.
• There are four types of transportation:

4. Cont’d
• Traction - large, heavy pebbles are rolled
along the river bed. This is most common
near the source of a river, as here
the load is larger.
• Saltation - pebbles are bounced along the
river bed, most commonly near the source.

5. Cont’d
• Suspension - lighter sediment is suspended
(carried) within the water, most commonly
near the mouth of the river.
• Solution - the transport of dissolved
chemicals. This varies along the river
depending on the presence of soluble
rocks.
