Clovis Caches
Author: Bruce B. Huckell
Publisher: UNM Press
ISBN: 0826354831
Category : Social Science
Languages : en
Pages : 266
Book Description
“A unique, significant contribution to our maturing studies of the Clovis era.”—Gary Haynes, author of The Early Settlement of North America: The Clovis Era The Paleoindian Clovis culture is known for distinctive stone and bone tools often associated with mammoth and bison remains, dating back some 13,500 years. While the term Clovis is known to every archaeology student, few books have detailed the specifics of Clovis archaeology. This collection of essays investigates caches of Clovis tools, many of which have only recently come to light. These caches are time capsules that allow archaeologists to examine Clovis tools at earlier stages of manufacture than the broken and discarded artifacts typically recovered from other sites. The studies comprising this volume treat methodological and theoretical issues including the recognition of Clovis caches, Clovis lithic technology, mobility, and land use.

A Numerical Investigation of Metabolic Reductive Dechlorination in DNAPL Source Zones
Author: John Anthony Christ
Publisher:
ISBN:
Category :
Languages : en
Pages : 632
Book Description
Among the most intractable environmental remediation problems are those involving the release of dense non-aqueous phase liquids (DNAPLs), such as chlorinated solvents, to the subsurface. Research efforts have focused on the use of numerical models to investigate reductions in contaminant concentrations due to partial mass removal and improvements in the performance of complementary source zone remediation technologies. Previous numerical investigations, however, have been limited to two-dimensional systems. Furthermore, a lack of models capable of simulating the most promising complementary technology, metabolic reductive dechlorination, has limited its application. This work developed and applied compositional multiphase numerical simulators to examine the influence of dimensionality (two-dimensions versus three-dimensions) on DNAPL source zone simulations and to investigate the benefits of stimulating metabolic reductive dechlorination at a chlorinated ethene-DNAPL contaminated site. Results from the dimensionality investigation showed that the simulation of DNAPL migration, entrapment, and dissolution in two dimensions provided reasonable approximations to the behavior simulated in three dimensions. Commonly employed saturation distribution and mass recovery metrics were approximately equivalent. Flux- averaged concentrations simulated in two dimensions, however, tended to be three to four times higher than those simulated in three dimensions. This difference was attributed to dilution at the down gradient boundary. An alternative metric, mass flux reduction, however, yielded better agreement.
