F.H. Nichols, D.A. Cacchione, D.E. Drake, J.K. Thompson
1989, Estuarine, Coastal and Shelf Science (29) 171-182
Two sequences of bottom photographs taken every two or four hours for two months during the Coastal Ocean Dynamics Experiment (CODE) off the Russian River, California, reveal the dynamic nature of interations between the water column, the sediments, and benthic organisms in the mid-shelf silt deposit.Time-lapse photographs taken between late...
Origin and age of the Lake Nyos maar, Cameroon
J. P. Lockwood, M. Rubin
1989, Journal of Volcanology and Geothermal Research (39) 117-124
Lake Nyos occupies a young maar crater in the Precambrian granitic terrane of northwest Cameroon. The lake is partly surrounded by poorly consolidated, ultramafic nodule-bearing pyroclastic surge deposits that were explosively ejected from the Nyos crater at the time of its formation. Radiocarbon dates show that the maar probably formed...
Distillation irrigation: A low-energy process for coupling water purification and drip irrigation
Jim Constantz
1989, Agricultural Water Management (15) 253-264
A method is proposed for combining solar distillation and drip irrigation to simultaneously desalinize water and apply this water to row crops. In this paper, the basic method is illustrated by a simple device constructed primarily of sheets of plastic, which uses solar energy to distill impaired water and apply...
Manganese oxidation model for rivers
Glen W. Hess, Byung R. Kim, Philip J.W. Roberts
1989, Water Resources Bulletin (25) 359-365
The presence of manganese in natural waters (>0.05 mg/L) degrades water-supply quality. A model was devised to predict the variation of manganese concentrations in river water released from an impoundment with the distance downstream. The model is one-dimensional and was calibrated using dissolved oxygen, biochemical oxygen demand, pH, manganese, and...
Estimating carcass fat and protein in northern pintails during the nonbreeding season
Michael R. Miller
1989, Journal of Wildlife Management (53) 123-129
I used northern pintails (Anas acuta) collected from August through March 1979-82 in the Sacramento Valley, California to derive equations to predict ether-extracted carcass fat, carcass protein, and skeletal lean dry weight. Ether-extracted carcass fat was best predicted by total fat depot weight (wet skin, abdominal fat, and intestinal fat)...
Speciation and equilibrium relations of soluble aluminum in a headwater stream at base flow and during rain events
Douglas A. Burns
1989, Water Resources Research (25) 1653-1665
In a small watershed in the Shenandoah National Park, Virginia, the short-term dynamics of soluble aluminum in stream water sampled during rain events differed significantly from stream water sampled during base flow conditions. Three fractions of dissolved aluminum were measured. The inorganic monomeric fraction made up approximately two thirds of...

Geographic information system/watershed model interface
Gary T. Fisher
1989, Conference Paper
Geographic information systems allow for the interactive analysis of spatial data related to water-resources investigations. A conceptual design for an interface between a geographic information system and a watershed model includes functions for the estimation of model parameter values. Design criteria include ease of use, minimal equipment requirements, a generic...

R. L. Hothem, H. M. Ohlendorf
1989, Archives of Environmental Contamination and Toxicology (18) 773-786
Plants, aquatic insects, and mosquitofish (Gambusia affinis) were collected from Kesterson Reservoir, Merced County, California, and a nearby reference site (Volta Wildlife Area) to compare concentrations of three contaminants found in 1985 with those reported in 1983 and 1984. Mean selenium concentrations in food-chain organisms from sites at Kesterson in...

Effect of site conditions on ground motion and damage
R. Borcherdt, G. Glassmoyer, M. Andrews, E. Cranswick
1989, Earthquake Spectra (5) 23-42
Results of seismologic studies conducted by the U.S. reconnaissance team in conjunction with Soviet colleagues following the tragic earthquakes of December 7, 1988, suggest that site conditions may have been a major factor in contributing to increased damage levels in Leninakan. As the potential severity of these effects in Leninakan...
Land drainage and estuarine salinity response
Jerad D. Bales
1989, Conference Paper
An investigation is being conducted to (1) quantify the short-term effects of freshwater agricultural drainage on salinity in a tidal creek and (2) evaluate the off-site effects of water-control structures on flow and water quality in channels that drain cropland in the Albemarle-Pamlico region of North Carolina. A continuous record...

J.Y. Bradshaw
1989, Journal of Geology (97) 697-717
Regionally extensive two-pyroxene granulite facies orthogneisses of Early Cretaceous age in Fiordland, southwest New Zealand, are criss-crossed by garnet-bearing feldspathic veins (and dikes) having associated marginal reaction zones of garnet granulite. The two-pyroxene granulites resulted from fluid-absent meta-morphism of a suite of...

Recorded seismic response of a base-isolated steel bridge carrying a steel water pipe
E. Safak, A. G. Brady
1989, Conference Paper, American Society of Mechanical Engineers, Pressure Vessels and Piping Division (Publication) PVP
A set of strong motion records was obtained from the base-isolated Santa Ana River Pipeline Bridge during the magnitude 5.9 Whittier Narrows, California, earthquake of October 1, 1987. The analysis of the records show that the level of excitation was not strong enough to fully activate the base isolators. The...

Rising water levels and the future of southeastern Louisiana swamp forests
W.H. Conner, M. Brody
1989, Estuaries (12) 318-323
An important factor contributing to the deterioration of wetland forests in Louisiana is increasing water levels resulting from eustatic sea-level rise and subsidence. Analyses of long-term water level records from the Barataria and Verret watersheds in southeastern Louisiana indicate an apparent sea level rise of about 1-m per century, mainly...

J.F. Walker, S.A. Pickard, W.C. Sonzogni
1989, Water Resources Bulletin (25) 139-147
Although several sophisticated nonpoint pollution models exist, few are available that are easy to use, cover a variety of conditions, and integrate a wide range of information to allow managers and planners to assess different control strategies. Here, a straightforward pollutant input accounting approach is presented in the form of...

Comparison of methods for estimating flood magnitudes on small streams in Georgia
Glen W. Hess, McGlone Price
1989, Water Resources Bulletin (25) 149-154
The U.S. Geological Survey has collected flood data for small, natural streams at many sites throughout Georgia during the past 20 years. Flood-frequency relations were developed for these data using four methods: (1) observed (log-Pearson Type III analysis) data, (2) rainfall-runoff model, (3) regional regression equations, and (4) map-model combination....
Mineral saturation states in natural waters and their sensitivity to thermodynamic and analytical errors
D. Kirk Nordstrom, James W. Ball
1989, Science Geological Bulletin (42) 269-280
Saturation indices computed with WATEQ4F chemical analyses from a groundwater in crystalline bedrock and a surface water receiving acid mine drainage are frequently at or above saturation with respect to calcite, fluorite, barite, gibbsite and ferrihydrite. Deep granitic groundwaters from Stripa, Sweden, are supersaturated with respect to calcite and fluorite....
