A simple approach to nonlinear estimation of physical systems
G. Christakos
1988, Mathematical and Computer Modelling (11) 583-588
Recursive algorithms for estimating the states of nonlinear physical systems are developed. This requires some key hypotheses regarding the structure of the underlying processes. Members of this class of random processes have several desirable properties for the nonlinear estimation of random signals. An assumption is made about the form of...
A multiple-objective optimal exploration strategy
G. Christakos, Ricardo A. Olea
1988, Mathematical and Computer Modelling (11) 413-418
Exploration for natural resources is accomplished through partial sampling of extensive domains. Such imperfect knowledge is subject to sampling error. Complex systems of equations resulting from modelling based on the theory of correlated random fields are reduced to simple analytical expressions providing global indices of estimation variance. The indices are...
Post-eruption changes in channel geometry of streams in the Toutle River drainage basin, 1983-85, Mount St. Helens, Washington
D. F. Meyer, J.E. Dodge
1988, Open-File Report 87-549
The May 18, 1980, eruption of Mount St. Helens generated a debris avalanche, lateral blast, lahars and tephra deposits that altered mainstream and tributary channels within the Toutle River drainage basin. Channel cross sections were monumented and surveyed on the North Fork Toutle River and its tributaries, South Fork Toutle...

1988, Professional Paper 1386-B
Of all the world's continents Antarctica is the coldest, the highest, and the least known. It is one and a half times the size of the United States, and on it lies 91 percent (30,109,800 km3) of the estimated volume of all the ice on Earth. Because so little is...
Analysis of alternative modifications for reducing backwater at the Interstate Highway 10 crossing of the Pearl River near Slidell, Louisiana
Gregg J. Wiche, J. J. Gilbert, David C. Froehlich, Jonathan K. Lee
1988, Water Supply Paper 2267
In April 1979 and April 1980, major flooding along the lower Pearl River caused extensive damage to homes located on the flood plain in the Slidell, Louisiana, area. In response to questions about causes of these floods and means of mitigating future floods, the U.S. Geological Survey, in cooperation with...
National water summary 1986: Hydrologic events and ground-water quality
United States Geological Survey
1988, Water Supply Paper 2325
Ground water is one of the most important natural resources of the United States and degradation of its quality could have a major effect on the welfare of the Nation. Currently (1985), ground water is the source of drinking water for 53 percent of the Nation's population and for more...

Effects of treated municipal effluent irrigation on ground water beneath sprayfields, Tallahassee, Florida
J. B. Pruitt, J. F. Elder, I. K. Johnson
1988, Water-Resources Investigations Report 88-4092
Groundwater quality data collection began in November 1979 at a spray-irrigation site near Tallahassee, Florida, before the initial application of secondary-treated municipal wastewater in November 1980. Effects of effluent irrigation on groundwater quality were evident about 1 year after spraying began and have continued to increase during the study period...

Channel morphology of Cottonwood Creek near Cottonwood, California, from 1940 to 1985
W. F. McCaffrey, J. C. Blodgett, J.L. Thornton
1988, Water-Resources Investigations Report 87-4251
Proposed construction of two dams on Cottonwood Creek California , has caused concern that resulting streamflow modification may alter downstream channel morphology. Baseline information on Cottonwood Creek channel characteristics from 1982-83 field surveys and 1940-84 aerial photographs indicates an alluvial channel that consists of a braided inner main channel within...
Flood-carrying capacities and changes in channels of the Lower Puyallup, White, and Carbon Rivers in western Washington
E. A. Prych
1988, Water-Resources Investigations Report 87-4129
The flood-carrying capacity of the Puyallup River 's leveed channel from its mouth to the city of Puyallup exceeds the 100-yr-flood discharge at most locations. Upstream from the city of Puyallup the flood-carrying capacity also is less than the 100-yr flood at many locations. In King County the flood-carrying capacity...

1988, Water-Resources Investigations Report 88-4056
The surficial aquifer system in Palm Beach County was studied during 1982-85 to determine the effects of increased urban and agricultural development on groundwater levels, flow directions, and quality. The surficial aquifer system and its geologic matrix are divisible into three zones on the bases of relative permeabilities and lithologic...
