A canal having side slopes 1:1 is proposed to be constructed in a cohesive soil to a depth of 10m below the ground surface. The soil properties are ϕu = 15⁰, Cu = 12 kPa, e = 1.00, Gs = 2.65. If Taylors stability number, Sn = 0.08 and if the canal flows full, the factor of safety with respect to cohesion failure against the failure of canal bank slopes will be most nearly equal to?

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.
