Biomass Growth in Unsaturated Porous Media: Hydraulic Properties Changes

The effect of the microbial growth on hydraulic properties of porous media is a topic studied in the framework of many applications, e.g. oil recovery, wastewater treatment, bioremediation, etc. (see [1]). Studies on flow through porous media in presence of biomass growth are presented in the papers by Rockhold et al. [2–4]. As stated there, additional work is needed for modelling unsaturated c...

Effective Unsaturated Hydraulic Conductivity

Steady-state and transient one-dimensional unsaturated flow in vertically stratified porous media are examined. Saturated hydraulic conductivity and the alpha parameter of the exponential hydraulic conductivity function were assumed to vary from soil layer to soil layer. The use of effective unsaturated hydraulic conductivity to compute matric potential in the soil profile is demonstrated. Resu...

Inverse modeling of a radial multistep outflow experiment for determining unsaturated hydraulic properties

Modeling flow and solute transport in the unsaturated zone on the basis of the Richards equation requires specifying values for unsaturated hydraulic conductivity and water potential as a function of saturation. The objectives of the paper are to evaluate the design of a transient, radial, multi-step outflow experiment, and to determine unsaturated hydraulic parameters using inverse modeling. W...
