Channel narrowing and vegetation development following a great plains flood
Jonathan M. Friedman, W. R. Osterkamp, William M. Lewis Jr.
1996, Ecology (77) 2167-2181
Streams in the plains of eastern Colorado are prone to intense floods following summer thunderstorms. Here, and in other semiarid and arid regions, channel recovery after a flood may take several decades. As a result, flood history strongly influences spatial and temporal variability in bottomland vegetation. Interpretation of these patterns...
Survival and recovery rates of American eiders in eastern North America

1996, Journal of Wildlife Management (60) 855-862
We analyzed banding and recovery data of adult female American eiders (Somateria mollissima dresseri) captured during the breeding season in eastern North America. We estimated survival rates for birds originating in the Atlantic Coast subpopulation to be 0.8730 ± 0.0156 (SE) while recovery rates were 0.0101 ± 0.0080 (SE). Support for...

Implementation and verification of a one-dimensional, unsteady-flow model for Spring Brook near Warrenville, Illinois
Mary J. Turner, Anthony P. Pulokas, Audrey L. Ishii
1996, Water Supply Paper 2455
A model based on de Sant-Venant equations for dynamic flow in open channels was calibrated and verified for a 0.75-mile urbanized reach of Spring Brook, a tributary to the West Branch Du Page River. The model was used to simulate flow in the reach, which passes through two short culverts,...

Occurrence of volatile organic compounds in ground water in the White River Basin, Indiana, 1994–95
Joseph M. Fenelon, Rhett C. Moore
1996, Fact Sheet 1996–0138
Water samples collected in 1994 and 1995 from 100 monitoring wells (91 shallow and 9 deep) screened in shallow unconsolidated aquifers in the White River Basin were analyzed for 58 volatile organic compounds (VOC’s). Twelve different VOC’s were detected. Chloroform was the most commonly detected VOC (found in 12 wells),...
South Florida Ecosystem Program: Quantifying freshwater discharge for coastal hydraulic control structures in eastern Dade County, Florida
Amit Kapadia, Eric D. Swain
1996, Fact Sheet 123-96
The South Florida Ecosystem Restoration Program is an intergovernmental effort, involving a number of agencies, to reestablish and maintain the ecosystem of south Florida. One element of the restoration effort is the development of a firm scientific basis for resource decision making. The U.S. Geological Survey (USGS), one of the...
Radon in the fluvial aquifers of the White River Basin, Indiana, 1995
Joseph M. Fenelon, Rhett C. Moore
1996, Fact Sheet 1996–0124
Water samples collected in 1995 from 57 monitoring wells (48 shallow and 9 deep) in the fluvial aquifers of the White River Basin were analyzed for radon. Radon concentrations in the shallow wells ranged from 140 to 1,600 pCi/L (picocuries per liter); the median concentration was 420 pCi/L. In comparison,...

1996, Fact Sheet 105-96
Geologic hazards in the Portland-Vancouver area include faults entirely hidden by river sediments, vegetation, and urban development. A recent aerial geophysical survey revealed patterns in the Earth's magnetic field that confirm the existence of a previously suspected fault running through Portland. It also indicated that this fault may pose a...

1996, Fact Sheet 095-96
VOC’s are carbon-containing chemicals that readily evaporate at normal air temperature and pressure. They are contained in many commercial products such as gasoline, paints, adhesives, solvents, wood preservatives, dry-cleaning agents, pesticides, cosmetics, correction fluid, and refrigerants. Approximately 15 million pounds of VOC’s were released to the atmosphere in the focused...

In order to determine the effects of stump height, year of cutting, parent-tree size, logging damage, and deer browsing on bigleaf maple (Acer macrophyllum) sprout clump development, maple trees were cut to two stump heights at three different times. Stump height had the greatest impact on sprout clump size. Two...
