3. In order to determine the equivalent permeability of a site approximately, a colored paint is poured into the borehole A. The time required for the paint to reach the borehole B was found to be 100 hours. The difference between the GWT levels at the boreholes A and B was measured to be 4.b meters and the length AB was measured as 100 m. Determine the equivalent permeability for this site. Try to guess the type of the soil at this site. (Note that equivalent permeability is geometric mean of the horizontal and vertical hydraulic conductivities of soil. For soils with a sloping surface it represents the hydraulic conductivity along the flow direction.) Seepage WT

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.

3. In order to determine the equivalent permeability of a site approximately, a colored paint is
poured into the borehole A. The time required for the paint to reach the borehole B was found
to be 100 hours. The difference between the GWT levels at the boreholes A and B was
measured to be 4.b meters and the length AB was measured as 100 m. Determine the
equivalent permeability for this site. Try to guess the type of the soil at this site.
(Note that equivalent permeability is geometric mean of the horizontal and vertical hydraulic
conductivities of soil. For soils with a sloping surface it represents the hydraulic conductivity
along the flow direction.)
