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.

The embankment for a highway 5097 ft long, 104 ft wide and 6 ft 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 6.748% and its porosity is 0.422. The specification requires the embankment be compacted to a dry unit weight of 122.874 lb/ft3. The specific gravity is 2.588. Determine the following: a. Total weight of the soil solids, kips. b. Total volume of the soil required from the borrow pit, ft3. c. Weight of water to be added per foot length of the embankment to reach 10% moisture content, lb.Round off answers to three decimal places.

In a fill section of a construction site, 1500 m3 of moist compacted soils is required. The design water content of the fill is 15%, and the design unit weight of the compacted soil is 18.5 kN/m3. Necessary soil is brought from a borrow site, with the soil having 12% natural water content, 17.5 kN/m3 wet unit weight, and Gs = 2.65. How much (in cubic meters) of the borrow material is required to fill the construction fill section? And how heavy is it?
Embankment is to be built with 15 km length of proposed road with 2 m height of road embankment. The cross sectional area of embankment and distance of borrow pit from embankment are 30 m² and 10 km respectively. Soil is to be compacted to 97 % of the max dry density. Information given as follows: (a) Results from laboratory compaction test: Max dry density-1.80 Mg/m³ Optimum water content=12% (b) Borrow material: Dry density-1.70 Mg/m² Water content-8% Calculate volume of additional water required for the entire volume of the embankment Final answer should be = 27, 486 m³
The proposed grading at a project site will consist of 25,100 m³ of cut and 23,300 m³ of fill and will be a balanced earthwork job. The cut area has an average moisture content of 8.3%. The fill will be compacted to an average relative compaction of 93% based on a maximum dry unit weight of 18.3 kN/m³ and an optimum moisture content of 12.9% obtained from the modified Proctor test. Compute the volume of water in kiloliters that will be required to bring these soils to the optimum moisture content.
