Consider the soil profile shown in Figure E3-2. The moist unit weight of the top sand layer is 20.0 kN/m³. Capillary rise is present above the groundwater table. The saturated unit weights of clay 1 and clay 2 are 17.8 and 18.5 kN/m³, respectively. Between these two clay layers is a sand seam of negligible thickness. The tip of Piezometer 1 is within this Sand seam. The tip of Piezometer 2 is at the bottom of the Clay 2 layer.

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.
