An embankment for a highway is to be constructed from a soil compacted to a dry unit weight of 18kN/m3. The clay has to be trucked to the site from a borrow pit. The bulk unit weight of the soil in the borrow pit is 17kN/m3 and its natural water content is 12.3%. Calculate the volume of clay from the borrow pit required for 1m3 of embankment. Assume G=2.7.

Sediment transport

Sediment transport or Soil transport is the movement of solid particles, usually due to the combination of gravitational forces acting on the sediment, and the movement of the liquid at which the sediment enters. Soil erosion occurs in natural systems where the particles are sandstones (sand, rocks), mud, or clay; the liquid is air, water, or ice; and the gravitational force that works to move particles to the landing surface. Sediment transportation or soil migration due to the movement of liquids occurs in rivers, lakes, lakes, oceans, and other bodies of water as a result of currents and waves. Transportation is also caused by glaciers as they flow, and to places on earth under the influence of wind. Soil erosion due to gravity alone is possible in most sloping areas, including hills, scarves, cliffs, and the continental shelf — the continental boundary of the slope.
