11. An embankment for a highway 30 m wide and 1.5 m thick is to be constructed from sandy soil, trucked in from a borrow pit. The water content of the sandy soil i the borrow pit is 15% and its void ratio is 0.69. Specifications require the embankment to compact to dry weight of 18 kN/m³. The length of the embankment is 1 km. a. What is the dry unit weight (in kN/m³) of sandy soil from the borrow pit to construct the embankment? Assume that Gs=2.7. b. What is the number of 10 m³ of truckloads of sandy soil required to construct the embankment? c. What is the weight (in kN) of water per truck load of sandy soil?

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.
