Soil profile is given in Figure 1. The ground water table is at a depth of 1.8 m below the ground surface. For the Silt layer, a soil sample (mass of 26.3 g) was collected from a depth of 2.5 m. It was dried in the oven at 105°C for 24 h and had mass of 22.1 g. Determine the vertical total and effective stresses at a depth of 7.0 m below the ground.

Principles of Seepage

In hydrology, when water flows down in a pore or crack of unsaturated soil due to gravity, the deep layer of soil is called seepage. It is the slow movement of water in the soil layer. Seepage is mainly found near hydraulic structures and is responsible for the stability of earthen-type hydraulic structures.
