Concept explainers

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.

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
An unlined irrigation canal is aligned parallel to a river, as shown in the figure. This cross section continues for 2.5 km. The soils are generally clays, but a 150 mm thick sand seam (k = 9x10-2 cm/s) is present as shown. Compute the water lost from the canal to the river, due to seepage through this sand layer per day.
CTTTT The soil in a borrow pit has a void ratio of 0.90. A fill of volume 20000 m³ has to be constructed with an in place dry density of 19.2 kN/m³. If the owner of borrow pit to be compensated at rate 2.5 per cubic metre of excavation, determine the cost of compensation. Take G = 2.68, Y = 9.81 kN/m³.
