For the soil profile shown in fig. top layer is sand. Initially the water table is 5m below ground level, which is lowered permanently to a depth of 15 m below ground level by pumping over few years. Assuming Yw= 10 kN/m³, unit wt. of sand above wt is equal to 18 kN/m³, unit wt. of sand sand clay below water table equals to 20 kN/m³. Coefficient of volume of compressibility is 0.25 m²/mN. 15 m 5 m 5 m hC Original GWT Lowered GWT Clay

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.
