Meaning and Definition
the sediment particles that are transported by a flowing water body (such as a river or stream) along its bed through rolling, sliding, or saltation.
The total material, including sand, gravel, cobbles, and boulders, that is moved along the bottom of a watercourse by the force of the current, as opposed to material carried in suspension. It is a key concept in fluvial geomorphology and sediment transport studies.

It is most commonly written as two separate words ('bed load') in modern technical English, though the hyphenated form 'bed-load' is also seen, especially as a modifier (e.g., bed-load transport).
Bed load moves by rolling, sliding, or bouncing along the streambed. Suspended load consists of finer particles (like silt and clay) that are carried within the flowing water itself, without frequent contact with the bed.
It is primarily used by geologists, hydrologists, geomorphologists, civil engineers (especially in water resources), and environmental scientists.
No, it is exclusively a noun. The action is described with phrases like 'transport as bed load', 'carry a bed load', or 'undergo bed-load transport'.
