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.

SITUATION 3 Determine the height of the infinite slope, H, such that the factor of safety of 3.1 is
maintained against sliding along the soil rock surface. Slope is inclined at 15° with respect to the
horizontal, unit weight of soil is 20 kN/m³, cohesion is 47 kPa, and angle of friction is 33º.
SITUATION 4 If downward seepage occurs on the same slope from Situation 3, determine H. Specific
gravity of soil is 2.75, void ratio is 0.70, and the soil from situation I is assumed to be 50% saturated.
