Reservoir anisotropy and facies stratigraphic framework in the Paleocene Fort Union Formation, western Wind River basin Reservoir anisotropy and facies stratigraphic framework in the Paleocene Fort Union Formation, western Wind River basin
Investigation of reservoir anisotropy and lithofacies stratigraphic framework in the Fort Union Formation in western Wind River Basin, Wyoming focused on excellent surface exposures in the Shotgun Butte, Eagle Point, and Shotgun Bench synclines, and in the Merriam anticline area of the Wind River Reservation (Fig. 1). A complementary study was made of the formation in the Muddy Ridge and...

Rheometry of natural sediment slurries Rheometry of natural sediment slurries
Recent experimental analyses of natural sediment slurries yield diverse results yet exhibit broad commonality of rheological responses under a range of conditions and shear rates. Results show that the relation between shear stress and shear rate is primarily nonlinear, that the relation can display marked hysteresis, that minimum shear stress can occur following yield, that physical...

Salt transport in a tidal canal, West Neck Creek, Virginia Salt transport in a tidal canal, West Neck Creek, Virginia
Flow and stability were monitored during 1989-92 in West Neck Creek, Virginia, which provides a direct hydraulic connection between the saline waters of Chesapeake Bay and the relatively fresh waters of Currituck Sound, North Carolina. Flow in the tidal creek was to the south 64 percent of the time, but 80 percent of the southward flows were less than 40 cubic feet per second. The...

Scour at a bridge over the Weldon River, Iowa Scour at a bridge over the Weldon River, Iowa
Contraction scour at the State Highway 2 bridge over the Weldon River in south-central Iowa was caused by a flood of record proportions on September 14 and 15, 1992. The peak discharge was 1, 930 cubic meters per second,which was 4 times the probable 100-year flood used to design the bridge, and resulted in road overflow. Contraction scour exposed the pier footings, but a subsurface...

Seismic reflection profiling: essential geophysical data for Yucca mountain, Nevada Seismic reflection profiling: essential geophysical data for Yucca mountain, Nevada
Yucca Mountain, Nevada, consists of a thick sequence of ashflow tuffs and lavas fractured into intact blocks with east-dipping strata, marginal broken zones characterized by dense faulting and brecciation, and intervening down-to-the-west fault zones with locally atypical west-dipping strata. Uncertainty in the structural setting of Yucca Mountain has resulted in multiple interpretations...

Selected precipitation characteristics in Antelope Valley, Mojave Desert, CA Selected precipitation characteristics in Antelope Valley, Mojave Desert, CA
An urban hydrology study currently in progress in Antelope Valley, California, includes the collection and analyses of precipitation and runoff data. Storms in Antelope Valley are most prevalent during the months of December, January, February, and March, but major storms have occurred during all months of the year except April, June, and July. The areal distribution of precipitation in...

Selenium in soil, water, sediment, and biota of the lower Sun River area, West-Central Montana Selenium in soil, water, sediment, and biota of the lower Sun River area, West-Central Montana
A U.S. Department of the Interior study started in 1990 examined the source, movement, fate, and possible biological effects of selenium associated with irrigation drainage from the Sun River Irrigation Project in west-central Montana. Concentrations of total selenium in soil samples ranged from 0.1 to 8.5 micrograms per gram; the maximum concentrations were measured in nonirrigated...

Short-term water and suspended-sediment fluctuations in a Louisiana marsh Short-term water and suspended-sediment fluctuations in a Louisiana marsh
To determine the timing of and driving forces for sediment suspension and deposition and the effect of impoundment, three self-recording instrument packages were deployed in a section of Louisiana marsh. Two of the packages went into an impoundment and one into an adjacent open, or control, area. A data logger in the package controlled sensors to measure water level, velocity, salinity...
