Transportation

Transportation - the movement of eroded material

The material a river has eroded is transported downstream.

There are four processes of transportation:

1. Traction

2. Saltation

3. Suspension

4. Solution

Traction

Traction is the first process of transportation. This is when large particles like boulders are pushed along the river bed by the force of the water.

Saltation

Saltation is the second process of transportation. In saltation, pebble-sized particles are bounced along the river bed by the force of the water.

Suspension

Suspension is the third process of transportation. This is where small particles like silt and clay are carried along by the water.

Solution is the fourth and final process of transporation. This is where soluble materials dissolve in the water and are carried along.
