Agarwat, S. K. et al. 
Activity and selectivity data for the oxidation of VOC containing air streams are reported over four commercial oxidation catalysts. The effect of VOC type and concentrations was investigated by using three different air streams containing VOCs typical of those expected from Air Force Groundwater air- strippers. The effect of reactor type was investigated by using the ARI catalyst both in the ...

Micellar Enhanced Ultrafiltration for Recovery and Concentration of Trichloroethylene in Groundwater
Roberts, B. L. et al. 
The objective of this experimental investigation was to determine the feasibility of micellar-enhanced ultrafiltration (MEUF) and vacuum stripping process in concentrating and separating trichloroethylene (TCE) from contaminated groundwater. The theory is to add surfactant to the contaminated groundwater to form micelles which bind the TCE molecules. The micelles containing the TCE are then re ...

Initial Field Trials of the Site Characterization and Analysis Penetrometer System (SCAPS). Reconnaissance of Jacksonville Naval Air Station Waste Oil and Solvents Disposal Site
Cooper, Stafford S. et al. 
At the request of the Naval Facilities Engineering Command (NAVFAC), Southern Division, Charleston, SC, the U.S. Army Engineer Waterways Experiment Station (WES) conducted the initial field trial of the Site Characterization and Analysis Penetrometer System (SCAPS) at Jacksonville Naval Air Station (NAS), Jacksonville FL. This work was carried out by a field crew consisting of personnel from W ...

Morella, G. L. 
This paper reviews attempts at signal detection in Gaussian noise using a higher order statistical (Higher Order Spectra (HOS) or polyspectra) technique. Examples comparing power spectral and bispectral analysis include the following topics: the identification of signals generated by a system of coupled nonlinear differential equations, radar backscatter processing and target identification, a ...

Three separate tests were conducted during the period of 1990 through 1992 in which a total of 60 AXKTs were deployed for purposes of gathering operational reliability of this developmental device. The three tests were done in differing environments to characterize the AXKT buoy over a range of conditions. In each of the tests, the buoys were deployed from a plane and the resulting data was re ...

Chasten, Monica A. et al. 
Detached breakwaters can be a viable method of shoreline stabilization and protection in the United States. Breakwaters can be designed to retard erosion of an existing beach, promote natural sedimentation to form a new beach, increase the longevity of a beach fill, and maintain a wide beach for storm damage reduction and recreation. The combination of low-crested breakwaters and planted marsh ...

Albertson, Paul E. et al. 
The investigation presented in this report provides a geomorphic framework for cultural resources evaluation along the Shreveport, LA, to Daingerfield, TX, reach of the Red River Waterway. The main focus of the study examined the Big Cypress Bayou portion of the proposed navigational project. The Red River segment was evaluated in general geomorphic terms and how its processes affect Caddo Lak ...

Buchanan, R. A. et al. 
During the first year of this project, comprehensive literature reviews were completed in the areas of (1) weldments employed in marine applications, (2) microbially influenced corrosion (MIC) in marine environments, and (3) MIC of weldments in marine environments. Specific weldment types covering a wide range of materials were selected for MIC evaluation. Laboratory MIC evaluations were initi ...
