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.

Solve with complete solutions and explain. An embankment for a highway 30 m wide and 1.5 m in compacted thickness is to be constructed from a sandy soil trucked from a borrow pit. The water content of the sandy soil in the borrow pit is 15% and its void ratio is 0.69. The swell index is 1.2. The specification requires the em-bankment to be compacted to a dry unit weight of 18 kN/m3. Determine, for a 1 km stretch of embankment, the weight of sandy soil from the borrow pit required to construct the embankment, the number of truckloads of sandy soil required for the construction. The full capacity of each truck is 22.2 m3 and local government policies require a maximum loaded capacity of 90%, the weight of water per truckload of sandy soil and the degree of satu-ration of the sandy soil in situ.
