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.

An embankment is to be constructed at a 5% moisture content. Material will be placed at the rate of 300 ccy/hr. The specified dry weight of the compacted fill is 2,700 lb/ccy. How many lbs of water must be dried each hour to decrease the moisture content of the material from 20% to 5% by weight?
Square concrete piles are arranged in 3 row by 4 column formation beneath the pile cap. These piles are embedded into several layers of cohesive soil. The first layer is 3.36m deep and the second layer is 3.42m deep. The total depth of the third layer was not fully captured in the geotechnical report and is assumed to extend indefinitely. The piles are 0.45m wide, and are spaced 1.45m apart from each other. Each pile span 11.89m in length. The first layer has c = 60 kPa and α = 1.00. The second layer has c = 87 kPa and α = 0.81. The third layer has c = 85 kPa and α = 0.70. The bearing capacity factor Nc is equal to 8.What is the group efficiency (%) for the pile? Consider ultimate capacities. Please answer this asap.
