Level II scour analysis for Bridge 8, (MANCTH00060008) on Town Highway 6, crossing Bourn Brook, Manchester, Vermont
Ronda L. Burns, Robert E. Hammond
1997, Open-File Report 97-813
This report provides the results of a detailed Level II analysis of scour potential at structure MANCTH00060008 on Town Highway 6 crossing Bourn Brook, Manchester, Vermont (figures 1–8). A Level II study is a basic engineering analysis of the site, including a quantitative analysis of stream stability and scour (U.S....
Beach loss along armored shorelines on Oahu, Hawaiian Islands
Charles H. Fletcher, Robert A. Mullane, Bruce M. Richmond
1997, Journal of Coastal Research (13) 209-215
An analysis of an aerial photographic time series of Oahu's shoreline reveals that historical seawall and revetment construction (coastal armoring) to protect eroding lands has caused the narrowing of 17.3 ± 1.5 km and loss of 10.4 ± 0.9 km of sandy beach over the period 1928 or 1949 to 1995. This...
Validation of behave fire behavior predictions in oak savannas
Keith W. Grabner, John Dwyer, Bruce E. Cutter
1997, General Technical Report NC-188
Prescribed fire is a valuable tool in the restoration and management of oak savannas. BEHAVE, a fire behavior prediction system developed by the United States Forest Service, can be a useful tool when managing oak savannas with prescribed fire. BEHAVE predictions of fire rate-of-spread and flame length were validated using...
Use of burrow entrances to indicate densities of Townsend's ground squirrels
Beatrice Van Horne, Robert L. Schooley, Steven T. Knick, Gail S. Olson, Kenneth P. Burnham
1997, Journal of Wildlife Management (61) 92-101
Counts of burrow entrances have been positively correlated with densities of semi-fossorial rodents and used as an index of densities. We evaluated their effectiveness in indexing densities of Townsend's ground squirrels (Spermophilus townsendii) in the Snake River Birds of Prey National Conservation Area (SRBOPNCA), Idaho, by comparing burrow entrance densities...
Test-trench studies in the Amargosa Desert, southern Nevada: Results and application of information to landfill covers in arid environments
Brian J. Andraski
Timothy D. Reynolds, Randall C. Morris, editor(s)
1997, Conference Paper, Conference proceedings: Landfill capping in the semi-arid west: Problems, perspectives, and solutions (ESRF-019)
As arid sites in the western United States are increasingly sought for disposal of the Nation's hazardous wastes and as volumes of locally generated wastes increase, concern about the potential effect of contaminants on environmental quality is being raised. Studies at the U.S. Geological Survey's Amargosa Desert research site near...
Why do international research and management?
Todd K. Fuller, Mark R. Fuller, R.M. DeGraaf
1997, Wildlife Society Bulletin (25) 74-77
The pheasant, in its North American range, seems to have had its greatest success in glaciated or in other areas associated with calcareous soils. Success has been slight in areas deficient in calcium.....In Lancaster County, Pennsylvania, no environmental difference other than presence or absence of limestone was discovered that might...
Endictya hendeyi sp. nov., a new coastal diatom species from North America
Eileen Hemphill-Haley, Albert D. Mahood
1997, Diatom Research (12) 35-42
Endictya hendeyi E. Hemphill-Haley sp. nov. is described from Recent and Quaternary, estuarine and marine deposits along the west coast of the United States. This taxon is distinguished by its 1) consistently small valves; 2) areolae of uniform size on the valve face in linear tangential rows; 3) prominent, external spatulate...
The geodetic signature of the M8.0 Oct. 9, 1995, Jalisco subduction earthquake
T. Melbourne, I. Carmichael, C. DeMets, K. Hudnut, O. Sanchez, J. Stock, G. Suarez, F. Webb
1997, Geophysical Research Letters (24) 715-718
The October, 1995 Mw 8.0 Jalisco subduction earthquake has provided a thorough geodetic observation of the coseismic subduction process. An 11 station regional GPS network located directly onshore of the rupture demonstrates consistent vertical subsidence verified by tide gauge data and southwest-directed extension, with measured displacements...
New composite spectra of Mars, 0.4-5.7 μm
Stephane Erard, Wendy M. Calvin
1997, Icarus (130) 449-460
About 15 areas were observed in the equatorial regions of Mars by the infrared spectrometers IRS (Mariner 6 and 7) and ISM (Phobos-2). The comparison between the spectra shows a remarkable consistency between two data sets acquired 20 years apart and calibrated independently. This similarity demonstrates the accuracy of ISM...
Non-double-couple earthquake mechanisms at the Hengill-Grensdalur volcanic complex, southwest Iceland
B.R. Julian, A.D. Miller, G.R. Foulger
1997, Geophysical Research Letters (24) 743-746
The Hengill-Grensdalur area in Iceland generates frequent small non-double-couple earthquakes with explosive volumetric components. We collected high quality three-component digital recordings of 4,000 earthquakes on a purpose-designed, 32-station network in 1991, and determined focal mechanisms for 100 of the best-recorded earthquakes by inverting amplitude ratios. Many...
