Analysis of blocking phenomena in bifurcated channels found in mountainous rivers
The paper presents an analysis of blocking phenomena in bifurcated channels found in mountain rivers. A change of channels may be caused by deposition of sediments which blocks the entrance...

Particle Dynamics and Bed Level Adjustments in a Mountain Stream
The focus of the study was the interaction of coarse bedload sheets with a near-static bed. At a critical discharge bed sediment was transported from upstream sources through the study...

Turbulent Velocities in a Mountain River
A weighted, electronic Pitot tube was deployed in the swift, boulder-bed Waiho river during a 46 m3/s flow and a 214 m3/s...

Hydraulics and Sediment Transport Processes in a Pool-Riffle Rocky Mountain Stream
Sediment transport processes related to varying channel-bed morphology were investigated from April to November, 1993 along a 1 km pool-riffle and step-pool reach of North Saint Vrain...

On Habitat Simulation in Mountain Rivers
Mountain rivers are quite different from other rivers and one of the characteristics that distinguish them from others is the large variation in velocities with time, with location in...

Relation Between Largest Known Flood Discharge and Elevation in Montana
Previous studies relating unit discharge to elevation indicated that large floods in the Rocky Mountains may be limited by elevation. However, high-elevation data are sparse in Montana...

Historic-Flood Evaluation and Research Needs in Mountainous Areas
An evaluation of historic flood estimates in mountainous areas in Colorado was made to assess their accuracy. The purpose of this evaluation is to enhance awareness of the need to assess...

Preliminary Report: The Little Skull Mountain Earthquake, June 29, 1992
The Little Skull Mountain earthquake occurred about 20 km from the potential high level nuclear repository at Yucca Mountain. The magnitude was 5.6, and the focal mechanism indicates normal...

Mud Mountain Dam Concrete Cutoff Wall
Mud Mountain Dam is an earth and rockfill flood control dam on the White River. The dam is located approximately 50 km southeast of Seattle, Washington. The dam was constructed in 1941...

The Use of Post-Tensioned Anchorages on the Arch Portion of Stewart Mountain Dam, Arizona
Post-tensioned rock anchorages were selected by the Bureau of Reclamation (Reclamation) to stabilize Stewart Mountain Dam against potential seismic loadings. The use of such anchorages...

Demonstration of a Risk-Based Approach to High-Level Repository Evaluatio Phase II

Photogeologic Reconnaissance of X-Tunnel at Little Skull Mountain
An underground structure known as X-tunnel was investigated for the viability as an underground deep based missile system that included the capability to maintain survivability following...

Earthquakes and Nuclear Waste: A Lesson in Media Relations
The Little Skull Mountain earthquake on June 29, 1992 marked the beginning of a challenging period for the U.S. Department of Energy's (DOE's) Yucca Mountain Site Characterization Project's...

Structure of Crater Flat and Yucca Mountain, Southeastern Nevada, as Inferred from Gravity Data
Existing gravity data in the vicinity of Yucca Mountain and Crater Flat have been examined to determine if these data support only the caldera model or if they support other geologic models...

IHLW Conference Paper—Yucca Mountain Site Characterization Project Environmental Protection Program
To ensure that characterization of the Yucca Mountain site is conducted in an environmentally safe and sound manner, the U.S. Department of Energy (DOE) has developed and implemented a...

Licensing and Permitting the Devil's Nose Project Under the 1990's Regulatory Conditions
Amador County is one of California's mountain counties of the western slope of the Sierra Nevada range in the north central portion of the state. The present population is estimated to...

Rocky Mountain Hydro
By May 1995, the $700 million Rocky Mountain Pumped Storage project will bring 850 MW of peaking power to a large part of the population in northwest Georgia. Its opening will mark only...

Storm Precipitation in Southwest British Columbia
The storm precipitation in a mountainous watershed in the southwestern British Columbia has been studied. Analysis of the spatial distribution of the storm features showed that the precipitation...

Precipitation Data in the Mountains of the Western United States: Do We Have What We Need?
Data collected by the National Weather Service and the Soil Conservation Service in the western United States are the primary sources of precipitation information for engineering and hydrologic...

Mountainous Precipitation Estimation Using Multivariate Statistical Analysis and Geographic Information Systems
Using rotated principal component analysis (PCA), unique, orthogonal spatial patterns of daily and monthly precipitation on a well-instrumented, mountainous watershed in Idaho (USA) were...
