An embankment with a total volume of 50000cu.m is to be constructed as a part of highway project. The soil to be used in the embankment will come from a borrow pit where the average moist unit weight and water content of 17.6KN/m3 and 15% respectively. Assuming the soil will be compacted to 95% of the maximum dry density of 18.2KN/m3. 1. The weight of the dry soil required. (kN) а. 364000 b. 864500 C. 512400 d. 756430 2.

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.
