Definition of Bedload:
Sediment transport mode in which individual particles either roll or slide along the seabed as a shallow, mobile layer a few particle diameters deep.[1].
This is the common definition for Bedload, other definitions can be discussed in the article


Bedload transport is the dominant sediment transport mode when the flow velocities (currents and wave-orbital velocities) are above the critical velocity for setting bed particles in motion (in the order of 0.2-0.4 m/s for sandy sediments), but insufficient for bringing sediment particles in suspension. Bedload transport occurs for non-cohesive medium-coarse sediments and is associated with the formation of bed ripples and dunes. The migration of these bedforms yields an estimate for the bedload transport.
