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

Calculate the hydraulic conductivity of the soil in cm/sec.
Determine the seepage velocity, in cm/sec, if the porosity of soil is 0.25.
Find the head difference, in mm, at t = 100 seconds.

Refer to the given figure below:
Length of specimen = 200 mm
Area of soil specimen = 1500 mm²
Area of stand pipe = 100 mm²
Head difference at time t = 0 is 500 mm
Head difference at time = 3 minutes is 300 mm
