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.

A uniform surcharge of 32kN/m² has been applied on the horizontal ground surface lying 8m above the top of a 4m thick, saturated clay layer. Above the clay is sand (Unit weight of sand=18KN/m2), and below the clay (Unit weight of clay=20kN/m) lied impervious rock. The final consolidation settlement in the clay layer has been calculated as 24mm. The point P lies 1.0m below the top of the clay layer. The coefficient of consolidation of the clay is 1.6m2/year. (Remainder Ty=C,.t/d). Just write the answers, no need to show calculations. a) What is the degree of consolidation at point P, when the pore pressure at P is 68kPa? b) How many years are required for 50% average degree of consolidation in the clay layer, if the relevant time factor is 0.196.? C) What is the effective stress at the middle of the sand layer immediately after the application of surcharge, if the drained and saturated unit weights of the sand are 16kNm3 and 18kN/m3, respectively. d) What is the increase in effective…

Effective Stresses in Soil Problem 3. A 4m thick of clay is overlain by 4m thick of sand. The ground water table is 1m below the natural grade line. Clay and sand have saturated unit weights of 19.5 and 17.3 kn/m³ respectively. Sand above the water retains water content of 30%. LL and void ratio of clay are respectively 60% and 27.3%. Specific gravity of sand solid is 2.7. 1. Find the compression index. 2. Find the moist unit weight of sand above the water table. 3. Find the effective soil pressure at mid clay layer.
