For questions 1-4, assume there is a 3-meter-deep soil layer (measured in the slope-normal direction) with a density of 1600 kg/m³, cohesion of 18 kPa, and a friction angle of 25 degrees. The potential failure plane is located at the soil-bedrock interface, is parallel to the surface, and has a slope of 35 degrees. As usual, assume the acceleration due to gravity is 9.8 m/s², and the density of water is 1000 kg/m³. 2. What is the hillslope’s factor of safety to the nearest tenth when the water table has a height of 1.5 m above the soil-bedrock interface (in the slope-normal direction)?

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 layer of fine sand exists over a stratum of impervious rock. The sand layer is 6.25m thick. The site is flooded and the water surface is 1.25m above the surface of the sand. It is proposed to excavate a very wide ditch through the site and to remove sand to a depth of 2.5m below the existing surface of the sand. One side of the excavation is to be supported by sheet piling driven to a depth of 4.4m below the existing surface of the sand. Draw a flow net and determine the seepage in m³/min per m length for the sand with a permeability of 0.18m/sec.
