Beer's Secret Ingredient: geology
As anyone in the beer business should know, water -- and what's in the water, courtesy of the geology through which it percolates -- can make all the difference in an end...

Soil-Cover Success
After seven years of operation and extensive vertical and lateral expansions, owners of the Kingsland Park Sanitary Landfill, located in northern New Jersey's Meadowlands,...

Sensitivity Analyses for Total-System Performance Assessment
As a follow-on to Sandia's 1991 preliminary total-system performance assessment of the Yuc1ca Mountain site, this paper presents results of some sensitivity analyses that were done using...

Investigation of Fracture-Matrix Interaction: Preliminary Experiments in a Simple System
Paramount to the modeling of unsaturated flow and transport through fractured porous media is a clear understanding of the processes controlling fracture-matrix interaction. As a first...

Effect of Interconnection of Fractures on Dispersion in Flow Through Fractured Networks
A stochastic modeling technique in a 2-D discrete fracture network with two orthogonal sets of fractures is developed to investigate mass transport dispersion and to investigate the relation...

Modeling Gravity-Driven Fingering in Rough-Walled Fractures Using Modified Percolation Theory
Pore scale invasion percolation theory is modified for imbibition of wetting fluids into fractures. The effects of gravity, local aperture field geometry, and local in-plane air/water...

Wetting Front Instability in an Initially Wet Unsaturated Fracture
Experimental results exploring gravity-driven wetting front instability in a pre-wetted, rough-walled analog fracture are presented. Initial conditions considered include a uniform moisture...
