A spatial length scale analysis of turbulent temperature and velocity fluctuations within and above an orchard canopy
Y.S. Wang, D.R. Miller, D.E. Anderson, R.M. Cionco, J.D. Lin
1992, Boundary-Layer Meteorology (59) 125-139
Turbulent flow within and above an almond orchard was measured with three-dimensional wind sensors and fine-wire thermocouple sensors arranged in a horizontal array. The data showed organized turbulent structures as indicated by coherent asymmetric ramp patterns in the time series traces across the sensor array. Space-time correlation analysis indicated that...

Acoustic waveform logging: Advances in theory and application
F.L. Paillet, C.H. Cheng, W.D. Pennington
1992, Log Analyst (33) 239-258
Full-waveform acoustic logging has made significant advances in both theory and application in recent years, and these advances have greatly increased the capability of log analysts to measure the physical properties of formations. Advances in theory provide the analytical tools required to understand the properties of measured seismic waves, and...

Groundwater use: Equilibrium between social benefits and potential environmental costs
M.R. Llamas, W. Back, J. Margat
1992, Hydrogeology Journal (1) 3-14
In many countries groundwater resources are under-appreciated and, therefore, underutilizied; whereas, in some areas they are inappropriately exploited and, therefore, over-utilized. “Over utilization” can lead to depletion in quantity or a degradation in quality or both. Obstacles to effective management include: (1) lack of knowledge of basic principles of...

Tensiometers: Theory, construction, and use
D.I. Stannard
1992, Geotechnical Testing Journal (15) 48-58
Standard tensiometers are used to measure matric potential as low as −870 cm of water in the unsaturated zone by creating a saturated hydraulic link between the soil water and a pressure sensor. The direction and, in some cases, quantity of water flux can be determined using multiple installations.A variety...
Geochemical heterogeneity in a sand and gravel aquifer: Effect of sediment mineralogy and particle size on the sorption of chlorobenzenes
Larry B. Barber II, E. Michael Thurman, Donald D. Runnells
1992, Journal of Contaminant Hydrology (9) 35-54
The effect of particle size, mineralogy and sediment organic carbon (SOC) on sorption of tetrachlorobenzene and pentachlorobenzene was evaluated using batch-isotherm experiments on sediment particle-size and mineralogical fractions from a sand and gravel aquifer, Cape Cod, Massachusetts. Concentration of SOC and sorption of chlorobenzenes increase with decreasing particle size. For...

Nitrate is a preferred electron acceptor for growth of freshwater selenate-respiring bacteria
Nisan A. Steinberg, Jodi Switzer Blum, Lawrence Hochstein, Ronald S. Oremland
1992, Applied and Environmental Microbiology (58) 426-428
An anaerobic, freshwater enrichment grew with either nitrate or selenate as an electron acceptor. With both ions present, nitrate reduction preceded selenate reduction. An isolate from the enrichment grew on either ion, but the presence of nitrate precluded the reduction of selenate. Stock cultures of denitrifiers grew anaerobically on nitrate...
Identification of persistent anionic surfactant-derived chemicals in sewage effluent and groundwater
Jennifer A. Field, Jerry A. Leenheer, Kevin A. Thorn, Larry B. Barber II, Colleen Rostad, Donald L. Macalady, Stephen R. Daniel
1992, Journal of Contaminant Hydrology (9) 55-78
Preparative isolation and fractionation procedures coupled with spectrometric analyses were used to identify surfactant-derived contaminants in sewage effluent and sewage-contaminated groundwater from a site located on Cape Cod, Massachusetts. Anionic surfactants and their biodegradation intermediates were isolated from field samples by ion exchange and fractionated by solvent extraction and adsorption...

Classifying and mapping wetlands and peat resources using digital cartography
Cornelia C. Cameron, David A. Emery
1992, Conference Paper, ASTM Special Technical Publication
Digital cartography allows the portrayal of spatial associations among diverse data types and is ideally suited for land use and resource analysis. We have developed methodology that uses digital cartography for the classification of wetlands and their associated peat resources and applied it to a 1:24 000 scale map area...
