WebThe soil sample as used in the experiment had a high permeability as it was a sandy soil, therefore the constant head permeability was the most suitable for determining the coefficient of permeability instead of the falling head permeability test which focuses on soils of low to intermediate permeability like clays. WebPermeability testing. Permeability (hydraulic conductivity) can be determined by undertaking in-situ tests in boreholes or standpipe piezometers. The test method involves variable head (rising or falling) or constant head procedures and requires knowledge of the groundwater level. The type of test undertaken depends on the soil type. alba seleqtta all inclusive
