Predicting the Hydraulic Conductivity of Unsaturated Soils from a Soil Moisture Profile
Publication: Unsaturated Soils 2006
Abstract
A model of dynamic soil moisture distribution in unsaturated soil is proposed as a simple solution to Klute's equation. This model can represent relationships among soil moisture, depth and elapsed time using a sigmoid function. By substituting this model into Klute's equation (the governing equation of one-dimensional vertical seepage flow in the unsteady state), Klute's equation can be solved easily and the hydraulic conductivity of unsaturated soil can be obtained without suction data.
