transport of sand and gravel

Experimental study of the transport of mixed sand and gravel

Each mixture used the same gravel, and sand was added to produce mixtures containing 6, 15, 21, 27, and 34% sand. Control of other variables allows us to isolate the effect of bed sand content on transport. As sand content increases, gravel transport rates increase by orders of magnitude, even though the proportion of gravel in the bed decreases.

Construction aggregates — like crushed stone, sand and gravel — are found in nearly every state in the nation, making long distance shipments of these materials unnecessary. As a result, freight trains, which typically specialize in long-haul movement of freight, may seem like an unlikely transportation partner.

Sediment transport - Wikipedia

Sediment transport is the movement of solid particles (), typically due to a combination of gravity acting on the sediment, and/or the movement of the fluid in which the sediment is entrained. Sediment transport occurs in natural systems where the particles are clastic rocks (sand, gravel, boulders, etc.), mud, or clay; the fluid is air, water, or ice; and the force of gravity acts to move the ...

Nov 11, 2006  The latter type of sediment distribution is usually represented by two modes, one of sand size and another of gravel. For this case, the movement of one mode becomes nonlinearly influenced by the other. As a result, the presence of the two modes in a bimodal material complicates the calculation of bed-load transport rates.
