WebSediment 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 … Webgeneral scour occurs as a result of the influence of the overall structure footprint on the seabed; and local scour occurs around localised areas, or members, of a structure (e.g. corners of a gravity base or piles).
