Regional equations for estimation of peak-streamflow frequency for natural basins in Texas
William H. Asquith, Raymond M. Slade Jr.
1997, Water-Resources Investigations Report 96-4307
Peak-streamflow frequency estimates are needed for flood-plain management; for objective assessment of flood risk; and for cost-effective design of dams, levees, other flood-control structures, roads, bridges, and culverts. Peak-streamflow frequency represents the peak discharges for recurrence intervals of 2, 5, 10, 25, 50, and 100 years. The U.S. Geological Survey,...

Temperature, snowmelt, and the onset of spring season landslides in the central Rocky Mountains
Alan F. Chleborad
1997, Open-File Report 97-27
Snow meltwater (snowmelt) that seeps into the subsurface is a major factor contributing to the development of landslides during the spring in mountainous areas of the Rocky Mountain region. An examination of historical temperature data in relation to spring season landslide occurrences reveals an association between the landslide events and...

The physics of debris flows
R.M. Iverson
1997, Reviews of Geophysics (35) 245-296
Recent advances in theory and experimentation motivate a thorough reassessment of the physics of debris flows. Analyses of flows of dry, granular solids and solid-fluid mixtures provide a foundation for a comprehensive debris flow theory, and experiments provide data that reveal the strengths and limitations of theoretical models. Both debris...

Paleomagnetic and 40Ar/39Ar geochronologic data from late Proterozoic mafic dikes and sills, Montana and Wyoming
Stephen S. Harlan, John William Geissman, Lawrence W. Snee
1997, Professional Paper 1580
Paleomagnetic and 40Ar/39Ar results from mafic dikes and sills in northwestern Wyoming and western Montana yield similar virtual geomagnetic poles and isotopic dates. In combination with paleomagnetic and geochronologic data from elsewhere in the western Cordillera, these data provide evidence for a regional mafic magnetic event at 780 to 770...
Real-time rainfall measurement in the City of Charlotte and Mecklenburg County, North Carolina
W. F. Hazell, Jerad D. Bales
1997, Fact Sheet 052-97
The U.S. Geological Survey (USGS) has measured rainfall at various locations in Mecklenburg County, North Carolina, since 1963. Between 1992 and 1997, the USGS, in cooperation with Charlotte Stormwater Services, installed 43 raingages throughout Mecklengburg County and adjoining counties. These 43 raingages, combined with three previously installed gages, compose a...
Kauai's endangered solitaires: Update on population status and distribution 1996
Michelle H. Reynolds, Thomas J. Snetsinger, Christina M. Herrmann
1997, Transactions of the Western Section of the Wildlife Society (33) 49-55
The puaioihi (Myadestes palmeri) and the kamao (M. myadestinus) are endangered solitaires endemic to Kauai in the Hawaiian Islands and now restricted to the Alakai Swamp. The puaiohi has been rare historically with population estimates declining since the first population surveys 1968-73. Puaiohi were believed to be on the verge...
Composition of the crust in the Grenville and Appalachian Provinces of North America inferred from VP/VS ratios
G. Musacchio, Walter D. Mooney, James H. Luetgert, Nikolas I. Christensen
1997, Journal of Geophysical Research B: Solid Earth (102) 15225-15241
We use the ratios between P and S wave velocities (VP/VS), derived from seismic refraction data, to infer the composition of the crust in the Grenville and the Appalachian Provinces of North America. The crust exhibits VP/VS increasing with depth from 1.64 to 1.84; there is a clear distinction between the Grenville...
