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.

One of the most challenging problems in environmental remediation is isolated blobs of contaminated fluid that become trapped in soils by capillary forces (i.e., surface tension). The pore space can be analyzed by analogy to a thin-diameter glass tube. Under the conditions given, what is the maximum length of water, I, that can be retained in the vertical glass tube shown? [mm] • contact angle 0 = 0⁰ • surface tension o= 72 dyn/cm = 0.072 N/m • tube diameter D = 2.0 mm • ● neglect the small volume of water above the meniscus the weight of water completely removes the curvature in the lower air-water interface

5. A permeameter of 8 cm diameter contains a sample of length 35 cm. Attachments are made it to enable conducting either constant head test or falling head test. The stand pipe used for conducting falling head test has a diameter of 2.5 cm. When constant head test was conducted the loss of head was 100 cm measured on a length of 25 cm. If the rate of flow was 2.7 cc/sec, calculate the coefficient of permeability of soil. If a falling head test is conducted on the same sample in the permeameter find the time taken for head to fall from 150 cm to 100 cm.
