2. Aquifer test - Wikipedia

   en.wikipedia.org/wiki/Aquifer_test

   Aquifer test. In hydrogeology, an aquifer test (or a pumping test) is conducted to evaluate an aquifer by "stimulating" the aquifer through constant pumping, and observing the aquifer's "response" (drawdown) in observation wells. Aquifer testing is a common tool that hydrogeologists use to characterize a system of aquifers, aquitards and flow ...

3. Atterberg limits - Wikipedia

   en.wikipedia.org/wiki/Atterberg_limits

   The Atterberg limits are a basic measure of the critical water contents of a fine-grained soil: its shrinkage limit, plastic limit, and liquid limit. Depending on its water content, soil may appear in one of four states: solid, semi-solid, plastic and liquid. In each state, the consistency and behavior of soil are different, and consequently so ...

4. Soil test - Wikipedia

   en.wikipedia.org/wiki/Soil_test

   A soil test is a laboratory or in-situ analysis to determine the chemical, physical or biological characteristics of a soil. Possibly the most widely conducted soil tests are those performed to estimate the plant-available concentrations of nutrients in order to provide fertilizer recommendations in agriculture.

5. Base-cation saturation ratio - Wikipedia

   en.wikipedia.org/wiki/Base-cation_saturation_ratio

   Base-cation saturation ratio (BCSR) is a method of interpreting soil test results that is widely used in sustainable agriculture, supported by the National Sustainable Agriculture Information Service (ATTRA) [ 1 ] and claimed to be successfully in use on over a million acres (4,000 km 2) of farmland worldwide. The traditional method, as used by ...

   en.wikipedia.org/wiki/Dilatancy_(granular_material)

   Dilatancy (granular material) Typical curves of stress -difference as a function of strain in dense sands. In soil mechanics, dilatancy or shear dilatancy[1] is the volume change observed in granular materials when they are subjected to shear deformations. [2][3] This effect was first described scientifically by Osborne Reynolds in 1885/1886 [4 ...

7. Sieve analysis - Wikipedia

   en.wikipedia.org/wiki/Sieve_analysis

   A sieve analysis (or gradation test) is a practice or procedure used in geology, civil engineering, [1] and chemical engineering [2] to assess the particle size distribution (also called gradation) of a granular material by allowing the material to pass through a series of sieves of progressively smaller mesh size and weighing the amount of material that is stopped by each sieve as a fraction ...
