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.

Question

Earth is required to be excavated from borrow pits for building an embankment as
shown in the figure below. The moisture unit weight of the borrow pits is 18 kN/m³
