Following are the results of a field dry unit weight determination test on a compacted soil by using the sand cone method with a custom-made, non-conventional sand-cone device: · . ● . . . (A) Calibrated dry density of Ottawa sand - 1667 kg/m³ Calibrated mass of Ottawa sand to fill the cone - 0.117 kg Mass of jar + cone + sand (before use) - 5.99 kg Mass of jar + cone + sand (after use) - 2.81 kg Mass of moist soil removed from hole - 3.331 kg Moisture content of moist soil - 11.6% Determine the dry unit weight of compaction in the field. (Show all pertinent volume-weight relationships and calculations.) (B) If the relative compaction in the field is reported to be 95.8%, what was the maximum dry unit weight of compaction obtained in the laboratory? (Show all pertinent volume-weight relationships and calculations.)

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.
