Our transcription: Smaller particles in transport as bed load, sand grains, for example, stay close to the bed of the stream but aren't in contact continuously. These particles actually move along in a series of jumps, hopping up into the flow, being pulled forward by the discharge, hitting the bottom, sometimes bouncing up themselves again, or ejecting another particle from the bed of the stream, which jumps up into the flow. This style of bed load transport is called "saltation."
