Effects of clay-water interactions on water retention in porous media

Creator:: Lenhard, Robert J. (Robert James)
Abstract:: Capillary pressure-saturation data obtained for unconsolidated porous media with different liquids are examined to investigate the effects of clay-liquid interactions on liquid retention. Liquid retention functions are assumed to reflect the effective pore-size distributions. The hydraulic variables, capillary pressure and saturation, are transformed to account for changes in liquid retention...

Estuarine sediment controls on trace metal distributions

Creator:: Davies-Colley, Robert J.
Abstract:: Sediments are the major compartment in aquatic environments for many materials of toxic or nutrient concern. The lack of knowledge of the phase associations of toxic metals in sediments is the largest deficiency in our understanding of the environmental hazard posed by metal contamination. This study examined the sedimentary partitioning...

Magmatism and mineralization of the Ash Peak area, Arizona : petrochemical interpretations

Creator:: Walker, Robert J.
Abstract:: Andesitic and rhyolitic magmatism was active during the mid- Tertiary (Early Miocene) of the Ash Peak area, southeastern Arizona. Andesitic magmas of similar composition both preceded and followed the low- and high-silica rhyolitic magmas. The changes from andesitic to rhyolitic and back to andesitic volcanism is postulated to be the...

Import and Consumer Impacts of U.S. AntiDumping Tariffs: Freshwater Crawfish from China

Creator:: Roberts, Kenneth J.
Abstract:: Few aquatic products of the United States have limited competition from imported supplies. This situation existed with the domestic supply of freshwater crawfish until 1994. The 52 thousand MT round weight domestic production from aquaculture and capture fisheries experienced major import competition at that point. Imports of value added crawfish...

Site ORBE2 : an archaeological analysis of a construction disturbed site

Creator:: Cromwell, Robert J.
Abstract:: This thesis describes investigations of archaeological materials recovered from Site ORBE2, an early-twentieth century historic site in Corvallis, OR. The archaeological materials were found only after construction workers had excavated trenches underneath the still-standing structure on the site in order to install a new foundation. Over 1500 artifacts were recovered...
