Laboratory Determination of Hydraulic Conductivity

Hydraulic conductivity is the measure of flowability of water inside the soil in the presence of a hydraulic gradient. The hydraulic gradient is defined as the difference in the water heads in the soil, which induces a water motion. In simple terms, a hydraulic gradient is the presence of a potential that induces a flow of water.

A falling head permeability test was carried out on a 15cm long of silty clay. The diameter of the sample and the stand pipe were 9.8cm and 0.75cm respectively. The water level in the stand pipe was observed to fall from 7ocm to 45cm in 12minutes. Determine the coefficient of permeability of the soil in m/day and the height of water level in stand pipe after 20minutes.
A constant head permeability test is performed on soil that is 4 cm2, and 2.5cm long. The head difference applied during the test is 20 cm and 7 cm3 is collected over a time of 100 sec. Then, falling head test is conducted on the same soil specimen at the same time (t1 – t2 = 100 sec), and the standpipe diameter is 0.8 cm. If the average head during the test should be 18 cm, what are h1 and h2 values, provide step by step solution solving h1 and h2 values.
