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.

3. A hydraulic backhoe excavator is excavating the basement of a large building. The heaped bucket capacity is 1.5 cu yd. The material is common earth with a bucket fill factor of 0.9. Job efficiency is equivalent to a 50-min hour. The machine's maximum depth of cut is 24 ft, and the average digging depth is 13 ft. The average swing angle is 90°. The cycle time for the excavator is 25 seconds. Some of the cut soil from the building project will be used for an earth-fill dam that requires a compacted volume of 64,000 yd'. The soil weighs 2,500 lb/LCY, 3,100 lb/BCY, and 3,500 lb/CCY. Estimate the hourly production in loose measure and the working days of the excavator required to complete the earth-fill dam.
