The following are given for a natural soil deposit: Moist unit weight, γ = 17.8 kN/m3 Moisture content, w = 14%; Gs = 2.7 This soil is to be excavated and transported to a construction site for use in a compacted fill. If the specification calls for the soil to be compacted at least to a dry unit weight of 18.4 kN/m3 at the same moisture content of 14%, how many cubic meters of soil from the excavation site are needed to produce 20,000m3 of compacted fill?

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.
