Methods of Determination
There are two broad categories of determining hydraulic conductivity:
- Empirical approach by which the hydraulic conductivity is correlated to soil properties like pore size and particle size (grain size) distributions, and soil texture
- Experimental approach by which the hydraulic conductivity is determined from hydraulic experiments using Darcy's law
The experimental approach is broadly classified into:
- Laboratory tests using soil samples subjected to hydraulic experiments
- Field tests (on site, in situ) that are differentiated into:
- small scale field tests, using observations of the water level in cavities in the soil
- large scale field tests, like pump tests in wells or by observing the functioning of existing horizontal drainage systems.
The small scale field tests are further subdivided into:
- infiltration tests in cavities above the water table
- slug tests in cavities below the water table

“If men got pregnant, there would be safe, reliable methods of birth control. They’d be inexpensive, too.”
—Anna Quindlen (b. 1952)
“I believe in women; and in their right to their own best possibilities in every department of life. I believe that the methods of dress practiced among women are a marked hindrance to the realization of these possibilities, and should be scorned or persuaded out of society.”
—Elizabeth Stuart Phelps (1844–1911)
