Semi-Analytical Modeling of Transient Stream Drawdown and Depletion in Response to Aquifer Pumping
Bwalya Malama, Ying-Fan Lin, Kristopher L. Kuhlman
Analytical and semi-analytical models for stream depletion with transient stream stage drawdown induced by groundwater pumping are developed to address a deficiency in existing mod…
Uncoupling electrokinetic flow solutions
Kristopher L. Kuhlman, Bwalya Malama
The continuum-scale electrokinetic porous-media flow and excess charge redistribution equations are uncoupled using eigenvalue decomposition. The uncoupling results in a pair of in…
Modeling cross-hole slug tests in an unconfined aquifer
Bwalya Malama, Kristopher L. Kuhlman, Ralf Brauchler +1
A modified version of a published slug test model for unconfined aquifers is applied to cross-hole slug test data collected in field tests conducted at the Widen site in Switzerlan…
Multiporosity Flow in Fractured Low-Permeability Rocks
Kristopher L. Kuhlman, Bwalya Malama, Jason E. Heath
A multiporosity extension of classical double and triple porosity fractured rock flow models for slightly compressible fluids is presented. The multiporosity model is an adaptation…
Core-scale solute transport model selection using Monte Carlo analysis
Bwalya Malama, Kristopher L. Kuhlman, Scott C. James
Model applicability to core-scale solute transport is evaluated using breakthrough data from column experiments conducted with conservative tracers tritium (H-3) and sodium-22, and…
Unsaturated Hydraulic Conductivity Models Based on Truncated Lognormal Pore-size Distributions
Bwalya Malama, Kristopher L. Kuhlman
We develop a closed-form three-parameter model for unsaturated hydraulic conductivity associated with the Kosugi three-parameter lognormal moisture retention model. The model deriv…
