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.

A falling head hydraulic conductivity test is performed on a sample of soil. The standpipe having a diameter 0.35 cm is observed and it takes 80 seconds for the water to drop by 70 cm from an initial hydraulic head of 90 cm. The sample has a length of 22 cm, and a diameter of 5 cm. Compute the rate of flow of water in the soil (in cm/s).
