Question-4: (a) The slope of a water-retaining embankment is 1 vertical, 2 horizontal and the vertical height is 10 m. The soil is fully saturated and has an undrained cohesion of 29 kPa and a unit weight of 20 KN/m3. Determine the factor of safety against shear failure along the trial circle shown in Fig. 1, when the water level is at the top of the embankment as shown in figure 1. Hint: (Area of slip mass is 184 m2)

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.
