Transport of solutes in complex hydrogeological media
This study presents numerical simulations of conservative solute transport in a complex heterogeneous porous media. A methodology to incorporate all the available information for describing the heterogeneity is developed. A Particle Tracking Random Walk method is used to simulate the solute …

Hydrogeological investigation of the Naukluft mountains, southwest Namibia
The Naukluft Mountains area is also referred to as the Naukluft Nappe Complex (NNC), that consist of northwest dipping carbonates and sandstones aged 750 Ma and form part of the Damara Super Group that has been thrust over the younger sedimentary rocks of the Nama Group, aged 550 Ma. In this study, …

Hydrogeological engineering approaches to investigate and characterize heterogeneous aquifers
… 5 and Appendix A). Chapters 2 through 5 present hydrogeological analysis approaches, while Appendix A is utilized within the dissertation introduction as an example of a non-physically based modeling approach, albeit demonstrated on a non-hydrogeologically based application. Chapter 2 presents an …

Hydrogeological characterization of the Akzo Salt Company, Williston Facility, Williston, North Dakota
<p> Operations at the Akzo Salt Company near Williston, ND, have resulted in saline contamination of the surface and subsurface in the general vicinity of the company property and possibly the surrounding area. The company site lies on the floodplain of Stony Creek and waste salt is buried just …

Groundwater Modeling and Hydrogeological Parameter Estimation: Potomac Aquifer System, SWIFT Research Center
… wells (MW) at the SWIFTRC were used to calculate hydrogeological parameters (transmissivity, hydraulic conductivity, specific storage, and storage coefficient). Two sets of data were analyzed from before and after TW-1 was rehabilitated to account for the change in the flow distribution to each …
