Instantaneous profile method

NettetThe Instantaneous Profile Method (IPM) is a technique that can be used to cap-ture the unsaturated hydraulic conductivity function of soils (Daniel 1982). In this method, the changes of the suction profile within a column of soil are measured as a function of time during the infiltration. The suction measurements can be per- Nettet4. sep. 2024 · In the laboratory, the instantaneous profile method has been routinely applied to determine the hydraulic conductivity of unsaturated compacted clayey soils. But the application of this method is often limited by the large-dimensions of water content probes such as TDR (Time Domaine Reflectometry) probes.
