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.

Determine the volume of water flowing through the sample shown in the figure per hour. There are 3 different soil layers and each is 200mm in length and diameter is 150mm. A constant head of 470mm is maintained across the soil sample. The porosity for Soil I is 0.5 and the value of k is 5*10^-3 cm/s. The porosity for Soil II is 0.55 and the value of k is 4.2*10^-2 cm/s. The porosity for Soil III is 0.35 and the value of k is 3.69*10^-4 cm/s.
