William H.K. Lee, Heiner Igel, Maria I. Todorovska, John R. Evans
2007, Open-File Report 2007-1263
Introduction Although effects of rotational motions due to earthquakes have long been observed (e. g., Mallet, 1862), nevertheless Richter (1958, p. 213) stated that: 'Perfectly general motion would also involve rotations about three perpendicular axes, and three more instruments for these. Theory indicates, and observation confirms, that such rotations are negligible.'...
Geospatial database of ground-water altitude and depth-to-ground-water data for Utah, 1971-2000
Susan G. Buto, Brent E. Jorgensen
2007, Data Series 302
A geospatial database of ground-water-level altitude and depth-to-ground-water data for Utah was developed. Water-level contours from selected published reports were converted to digital Geographic Information System format and attributes describing the contours were added. Water-level altitude values were input to an inverse distance weighted interpolator to create a...

Radiometric calibration status of Landsat-7 and Landsat-5
Julia A. Barsi, Brian L. Markham, Dennis Helder, Gyanesh Chander
2007, Conference Paper
Launched in April 1999, Landsat-7 ETM+ continues to acquire data globally. The Scan Line Corrector in failure in 2003 has affected ground coverage and the recent switch to Bumper Mode operations in April 2007 has degraded the internal geometric accuracy of the data, but the radiometry has been unaffected. The...

Bankfull Regional Curves for Streams in the Non-Urban, Non-Tidal Coastal Plain Physiographic Province, Virginia and Maryland
Jennifer L. Krstolic, Jeffrey J. Chaplin
2007, Scientific Investigations Report 2007-5162
Natural-channel design involves constructing a stream channel with the dimensions, slope, and plan-view pattern that would be expected to transport water and sediment and yet maintain habitat and aesthetics consistent with unimpaired reaches. The adequate description of channel geometry in unimpaired reaches often is an important component of natural-channel design...
Regionalized equations for bankfull discharge and channel characteristics of streams in New York State — Hydrologic Regions 1 and 2 in the Adirondack Region of northern New York
Christiane I. Mulvihill, Amy Filopowicz, Arthur Coleman, Barry P. Baldigo
2007, Scientific Investigations Report 2007-5189
Equations that relate drainage area to bankfull discharge and channel characteristics (width, depth, and cross-sectional area) at gaged sites are needed to define bankfull-discharge and channel characteristics at ungaged sites and to provide information for watershed assessments, stream-channel classification, and design of stream-restoration projects. Such equations are most accurate if...

Time scales and volumes of large ignimbrite-caldera eruptions in continental arc: Relation to assembly of subvolcanic batholiths
Peter W. Lipman
2007, Conference Paper, State of the Arc
Volcanoes and upper-crustal plutons in diverse geologic settings tend to share common features of mineral and chemical compositions, emplacement age, and magmatic volume. Voluminous silicic ignimbrites associated with caldera sources, widespread components of Cordilleran arcs, have commonly been interpreted as broadly concurrent with assembly of upper-crustal batholiths. Tertiary ignimbrites in...
