Problem2) A sample, 75 mm in diameter and 20 mm high, taken from a clay layer 10 m thick, was tested in an odometer with drainage at the upper and lower boundaries. It took the laboratory sample 30 minutes to reach 50% consolidation. How much more time would it take the 10-m clay layer to achieve 50% consolidation if drainage existed on the upper and lower boundaries?

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.
