MICROSCALE CONTROLS ON THE FATE OF CONTAMINANT URANIUM IN THE VADOSE ZONE, HANFORD SITE, WASHINGTON

McKinley J.P.; Zachara J.M.; Liu C.; Heald S.C.; Prenitzer B.I.; Kempshall B.W. (2006)

An alkaline brine containing uranyl (UO22+) leaked to the thick unsaturated zone at the Hanford Site. We examined samples from this zone at microscopic scale to determine the mode of uranium occurrence-microprecipitates ...
QUANTIFYING CO2 FLUXES FROM SOIL SURFACES TO THE ATMOSPHERE

Kabwe L.K.; Hendry M.J.; Wilson G.W.; Lawrence J.R. (2002)

Measurements of CO2 fluxes from ground surface of the atmosphere (soil respiration) are needed to quantify biotic and abiotic reaction rates in unsaturated zones and to gain insight into the importance of these processes ...
SURFACTANT EFFECTS ON UNSATURATED FLOW IN POROUS MEDIA WITH HYSTERESIS: HORIZONTAL COLUMN EXPERIMENTS AND NUMERICAL MODELING

Henry E.J.; Smith J.E.; Warrick A.W. (2001)

Many organic compounds depress the surface tension of water relative to their aqueous concentration. These surface-active organic solutes have been shown to cause water flow in unsaturated porous media. Flow in these systems ...
TEMPORAL AND SPATIAL (DOWN PROFILE) VARIABILITY OF UNSATURATED SOIL HYDRAULIC PROPERTIES DETERMINED FROM A COMBINATION OF REPEATED FIELD EXPERIMENTS AND INVERSE MODELING

Olyphant G.A. (2003)

An in situ method for estimating parameters necessary for characterizing unsaturated flow in porous media has been applied to 37 individual data sets from the same study site (a sand dune on the edge of a wetland). The ...
