Real-time monitoring of bluff stability at Woodway, Washington, USA
On January 15, 1997, a landslide of approximately 100,000-m3 from a coastal bluff swept five cars of a freight train into Puget Sound at Woodway, Washington, USA, 25 km north of downtown Seattle. The landslide resulted from failure of a sequence of dense sands and hard silts of glacial and non-glacial origin, including the Lawton Clay, a hard, jointed clayey silt that rarely fails in natural slope

Relationships between Boron concentrations and trout in the firehole river, Wyoming: Historical information and preliminary results of a field study
The Firehole River (FHR) in Yellowstone National Park (YNP) is a world- renowned recreational fishery that predominantly includes rainbow trout (RBT, Oncorhynchus mykiss) and brown trout (BNT, Salmo trutta). The trout populations apparently are closed to immigration and have been self- sustaining since 1955. Inputs from hot springs and geysers increase the temperature and mineral content of the wa

Scour measurements at contracted highway crossings in Minnesota, 1997
During record flooding in the Minnesota River basin in April 1997, the U.S. Geological Survey, in cooperation with the Federal Highway Administration, collected real-time scour measurements at contracted bridge openings and provided data collection assistance to the Minnesota Department of Transportation bridge inspectors. Weather and flood plain vegetation restricted data collection to what could

Sediment transport capacity as an objective of reservoir operations
A sediment transport capacity index was developed as a part of a program to develop methods of flushing flow analysis. The index can be used to develop reservoir operation strategies that consider the movement of sediment as one of the reservoir management goals. The sedimentation transport capacity index determines the instream flow for the maintenance of the substrate below a reservoir in a cond

Some trans-Iapetus conodont faunal connections in the Tremadocian
Paleobiogeographical barriers within the Iapetus Ocean effectively restricted conodont faunas in Baltica from contact with those in Laurentia during Tremadocian time. Only species of Cordylodus, Paltodus, Drepanodus, Paroistodus and Iapetognathus have been reported to occur on both sides of the Iapetus Ocean. Continued studies of faunas from deeper platform and slope settings of North America (Lau

Tectonic controls on fault-zone permeability in a geothermal reservoir at Dixie Valley, Nevada
To determine factors controlling permeability variations within and adjacent to a fault-hosted geothermal reservoir at Dixie Valley, Nevada, we conducted borehole televiewer observations of wellbore failure (breakouts and cooling cracks) together with hydraulic fracturing stress measurements in six wells drilled into the Stillwater fault zone at depths of 2 to 3 km. Measurements in highly permeabl

Tidal creek changes at the Sonoma Baylands restoration site
Over the past 150 years, human activity has had a major impact on tidal wetlands adjoining the San Francisco Bay-Delta estuary Growing concern about the effect of this change on the ecology of the estuary has prompted Bay area managers to attempt to reclaim tidal wetlands. The Sonoma Baylands Restoration Project is designed to use dredge material to convert 348 acres from farmland to wetland. This

Use of acoustic velocity methodology and remote sensing techniques to measure unsteady flow on the lower Yazoo River in Mississippi
Methodologies have been developed for computing continuous discharge during varied, non-uniform low and medium flows on the Yazoo River at the U.S. Geological Survey streamgage below Steele Bayou near Long Lake, Mississippi, using acoustic signal processing and conventional streamgaging techniques. Procedures were also developed to compute locations of discharges during future high flow events whe
