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 soil sample 14 cm in diameter is placed in a tube 1m long. A constant supply of water is allowed to flow into one end of the soil at A and the outflow of B is collected by a bearer. The average amount of water collected is 1.4 cubic centimeter every 8 seconds. The tube is inclined and has a head difference of 2.3 m. Give the seepage velocity if porosity is 0.291.
(e) A soil profile consists of a clay layer between layers of sand, the water table being in theupper sand layer. Before the construction of a raft foundation for a large reservoir, piezometers were placed in the saturated clay layer. The whole process of filling the reservoir may be approximated to applying rapidly a single pressure increment of 200 kPa uniformly throughout the clay layer. One year after filling the reservoir, the piezometers indicated a distribution of excess porewater pressure as indicated in Figure Q-e. Estimate the average degree of consolidation at this time.
