Hysteresis and dynamic effects in the relationship between capillary pressure, saturation, and air-water interfacial area in porous media.
(2006)
Air-water interfacial areas (A) were measured for multiple drainages (primary, secondary, and scanning) using a newly developed method, along hysteretic Pc-S curves representing natural drying/wetting processes. The ...
Novel, low-cost aluminum (hydr)oxide based materials for fluoride-impacted drinking-water: Batch and column studies
(2016-05)
Simple aluminum (hydr)oxides and layered double hydroxides were synthesized using common chemicals and equipment by varying synthesis temperature, concentrations of extra sulfate and citrate, and metal oxide amendments. ...
Utilization of coal combustion by-products for in situ treatment of acidic mine waters.
(1999)
The goal of this research was to determine how to effectively treat AMD in situ using CCBs and to develop a better understanding of the chemical and physical processes involved with the treatment. AMD treatment within the ...
An investigation of alcohol tracer partition coefficients and a study of simulations.
(1999)
The secondary objective of this research was to demonstrate the advantages of the UTCHEM simulator in developing effective design strategies for hum tests and surfactant flooding processes. During a column study, there was ...
INVESTIGATION OF THE HYDROLOGY, FLUVIAL GEOMORPHOLOGY, AND SEDIMENT TRANSPORT IN THE LAKE THUNDERBIRD WATERSHED IN CENTRAL OKLAHOMA
(2015-05-08)
As human population continues to rise, an ever increasing burden is being placed on earth’s water resources. Between 1950 and 2010, the world’s population increased from 2.6 billion to almost 7 billion, and the population ...
Iron and sulfur microbial processes applied to the biodegradation of organic contaminants in groundwater.
(1998)
This research emphasizes microbial/mineral interactions associated with Fe$\sp{3+}$ and SO$\sb4\sp{2-}$ reduction. Simplified methods are developed to evaluate Fe$\sp{3+}, $ Fe$\sp{2+}, $ and S mineral species. These ...
Quantifying the Impact of Experimental Factors on the Measurement of Dynamic Capillary Effects in Unsaturated Porous Media
(2014-12-12)
Multiphase flow is an important phenomenon in many natural and engineering systems; for example, oil recovery and water movement in the unsaturated zone are two common multiphase flow systems. The capillary pressure-saturation ...
Development of ecological engineering solutions to mine water biogeochemistry and hydrology challenges
(2022-05)
Abandoned underground mines can cause a variety of environmental problems, including mine drainage (MD) that negatively impacts thousands of kilometers of streams worldwide. Underground mines accumulate water after pumping ...
Effects of pH, inorganic anions, and surfactants on the photocatalytic degradation of aqueous ammonia in graywater.
(2007)
Key words: Aqueous ammonia, Titanium dioxide, pH, Inorganic anions, Surfactants, Hydroxyl radicals, Graywater
Quantification of chlorophyll in small reservoirs using airborne video imagery.
(1998)
The primary objective of this study was to develop a rapid, economic method of assessing water quality and productivity in surface impoundments. Airborne video cameras equipped with narrow band filters were used to assess ...
