Title: Hydraulic Conductivity of Saturated Soils: Field Methods
Abstract: The hydraulic conductivity is a measure of a soil's ability to transmit water. Water movement, whether under saturated or unsaturated conditions, is highly dependent on the hydraulic conductivity. The most common methods to determine the saturated hydraulic conductivity of the soil in the presence of a water table are the augerhole method and the piezometer method. The pit-bailing method was developed by Healy and Laak to measure the in situ saturated hydraulic conductivity for septic-tank drain-field design. The methods to determine the saturated hydraulic conductivity in locations above a water table or in the absence of a water table are more elaborate and time consuming. In fact, a large quantity of water may be needed to saturate the nearby soil before the measurement. These methods include the double-tube method, shallow well pump-in method, cylindrical permeameter method, air entry permeameter and infiltration gradient technique.
