A Borehole Instrumentation Program for Characterization of Unsaturated-Zone Percolation

Some Features of the Initial Stage of Sediment Motion in Water Flows

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 Contaminant Migration from an Unlined Pond
A hybrid one-dimensional (1-D) vertical model coupled with a two-dimensional (2-D) aquifer model was applied to study the fate and transport of arsenic, fluoride, and orthophosphate resulting...
