What is the Hjulstrom Curve all about?

The Hjulstrom Curve is a very useful tool in the study of rivers. It shows what size material will be entrained (picked up), transported and deposited at different velocities.

Whilst you might expect the smallest particles to require the least energy to pick up, this is not always true, as the smallest particles often carry a charge, which allows them to flocculate (stick together). This means that they actually require higher velocities to be entrained than particles which are slightly bigger.
