High-order averaging method of hydraulic conductivity for accurate soil moisture modeling

Computer Erosion Modeling Considering Soil Hydraulic Conductivity

Improved computer models of erosion have been developed, considering soil hydraulic conductivity. The models deal with erosion of levees, dams and embankments due to overtopping. The simulations trace the formation of rills and gullies, beginning with initial overtopping and continuing to final breaching. Physical models performed at 1-g and high g using a geotechnical centrifuge have been used...

A new method for high-resolution characterization of hydraulic conductivity

[1] A new probe has been developed for high-resolution characterization of hydraulic conductivity (K) in shallow unconsolidated formations. The probe was recently applied at the Macrodispersion Experiment (MADE) site in Mississippi where K was rapidly characterized at a resolution as fine as 0.015 m, which has not previously been possible. Eleven profiles were obtained with K varying up to 7 or...

Comment on ‘‘Inverse groundwater modeling for hydraulic conductivity estimation using Bayesian model averaging

[1] Tsai and Li [2008] assert that the Bayesian information criterion (BIC) [Schwarz, 1978] is better suited for comparing models having different parameters than is the Kashyap criterion (KIC) [Kashyap, 1982] because a Fisher information term in the latter may rank models with relatively large parameter estimation uncertainties higher than other models. We start by noting that KIC reduces asym...
