Percolation testing and hydraulic conductivity of soils for percolation areas

摘要

The results of specific percolation tests are expressed in terms of field saturated hydraulic conductivity (Kfs) of the soil. The specific tests comprise the Irish SR 6 and the UK BS 6297 standard tests and the invested auger hole and square hole tests employed for the design of land drainage. Peroclation times from these tests are coverted to K_fs values using unit gradient theory and the Elrick and Reynolds (Soil Sci.
