A computer program for calculating relative-transmissivity input arrays to aid model calibration
Emanuel Weiss
1982, Open-File Report 82-447
A program is documented that calculates a transmissivity distribution for input to a digital ground-water flow model. Factors that are taken into account in the calculation are: aquifer thickness, ground-water viscosity and its dependence on temperature and dissolved solids, and permeability and its dependence on overburden pressure. Other factors affecting...
Techniques for estimating flood discharges for unregulated streams in New Mexico
Richard P. Thomas, Robert L. Gold
1982, Water-Resources Investigations Report 82-24
Equations for estimating flood magnitudes at selected recurrence intervals from 2 to 500 years were developed using multiple-regression analyses. These equations relate flood magnitudes to basin characteristics, contributing drainage area and site altitude, and only are applicable to unregulated streams in New Mexico that are relatively unaffected by urban runoff....

On Lagrangian residual currents with applications in south San Francisco Bay, California
Ralph T. Cheng, Vincenzo Casulli
1982, Water Resources Research (18) 1652-1662
The Lagrangian residual circulation has often been introduced as the sum of the Eulerian residual circulation and the Stokes' drift. Unfortunately, this definition of the Lagrangian residual circulation is conceptually incorrect because both the Eulerian residual circulation and the Stokes' drift are Eulerian variables. In this paper a...
Some observations on the ecology and fish management of reservoirs in the United States
N. G. Benson
1982, Canadian Water Resources Journal (7) 2-25
By 1980 there were 1,608 reservoirs (over 202 ha each) with a surface area of 4 million ha in the United States. Construction of new reservoirs has decreased in recent years because of the lack of suitable sites and the opposition of environmental interests. Reservoirs have characteristics of both lacustrine...

The most important of these ideas are:Differences in topographic elevation provide the principal driving force for regional flow.Flow through confining layers...
Marine ice-pushed boulder ridge, Beaufort Sea, Alaska
Peter W. Barnes
1982, Arctic (35) 312-316
A steep-faced boulder ridge up to 4m high by 300m long was encountered along the arctic coast east of Prudhoe Bay, Alaska, in the summer of 1979. Marine occurrences of similar ridges are rare. Since ice-push sorts cobble- and boulder-sized material in the construction of a ridge, recent onshore excursions of ice due to wind stress on the fast ice...
Representation of multiaquifer well effects in three-dimensional ground-water flow simulation
Gordon D. Bennett, Angelo L. Kontis, Steven P. Larson
1982, Groundwater (20) 334-341
The presence of multiaquifer or multilayer wells changes the nature of the equations which must be solved in a three-dimensional ground-water flow simulation and, in effect, alters the stencil of computation. A method has been devised which takes this change into consideration by allowing simulation of the hydraulic effects of...

1982, Conference Paper, Marine birds: Their feeding ecology and commercial fisheries relationships
Band recoveries (N = 315) over 26 years (1951-77) and three surveys of seabird bycatch in inshore fishing nets (1972, 1980-81) indicate that there has been a substantial net-mortality of Atlantic Puffins (Fratercula arctica) and Common Murres (Uria aalge) in Newfoundland coastal waters for the past 2 decades. Offshore (e.g....
Paleoenvironment and age of kaolin deposits in the Andersonville district, Georgia
Harland E. Cofer, Norman O. Frederiksen
1982, Conference Paper, Proceedings: Second Symposium on the Geology of the Southeastern Coastal Plain
The kaolin deposits of the Andersonville district of Georgia are thick and relatively pure; they grade laterally and vertically into sandy kaolin and sand. The sedimentological and mineralogical character of the clay and the enclosing sand suggests deposition in a marine shallow-water to estuarine environment. Palynomorph and invertebrate fossil assemblages...

B.W. Rehm, S.R. Moran, G.H. Groenewold
1982, Journal of Hydrology (59) 293-314
The magnitude of groundwater recharge to coal aquifers in a 150-km2 area in west-central North Dakota was determined using three separate approaches: (1) the net water level rise in water-table wells; (2) calculations of the fluid flux between nested piezometers, using the Darcy equation and measured values of hydraulic conductivity and...
Adsorption of natural dissolved organic matter at the oxide/water interface
James A. Davis
1982, Geochimica et Cosmochimica Acta (46) 2381-2393
Natural organic matter is readily adsorbed by alumina and kaolinite in the pH range of natural waters. Adsorption occurs by complex formation between surface hydroxyls and the acidic functional groups of the organic matter. Oxides with relatively acidic surface hydroxyls, e.g. silica, do not react strongly with the organic matter....

Guidelines for finding concretionary Mn-Fe oxides in streams
G.A. Nowlan
1982, Journal of Geochemical Exploration (17) 77-79
Concretionary Mn-Fe oxides in streams form at interfaces between oxidizing and reducing environments. A reducing environment produces waters high in dissolved Mn and Fe, and an oxidizing environment causes precipitation. Mineralogical, microprobe, and optical studies of concretionary Mn-Fe oxides may further our understanding of the role of Mn-Fe oxides in...
