The soil profile at a site for a proposed office building consists of a layer of fine sand 10.4 m thick above a layer of soft clay 2 m thick. Below the soft clay is a deposit of coarse sand. The groundwater table was observed at 3 m below ground level. The void ratio of the sand is 0.76. The building will impose a vertical stress increase of 140 kPa at the middle of the clay layer and the clay is overconsolidated with an OCR = 2.5 and a water content of 38%. Estimate the primary consolidation settlement of the clay. Assume the soil above the water table to be saturated, Cc=0.3, Cs = 0.05 and Gs=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.
