Reference Number
USACE EM 1110-2-1906
Material
Soil
Test Property
Permeability, Flow Rate, Hydraulic conductivity
Description of Test
This test method covers laboratory measurement of the hydraulic conductivity (also referred to as coefficient of permeability) of water-saturated porous materials with a flexible wall permeameter. This test method may be utilized with undisturbed or compacted specimens having a hydraulic conductivity less than or equal to 1x10-5m/s (1x10-3cm/s). The hydraulic conductivity of materials with hydraulic conductivities greater the 1x10-5m/s may be determined by Test Method D2434. This test method applies to one-dimensional, laminar flow of water within porous materials such as soil and rock.
Number of Test Specimens
1
Test Specimen Size
Minimum diameter of 1.0 in x 1in height, with the largest particle size 1/6 the diameter of the specimen.
