If there is a single theme that unifies the diverse papers in this chapter, it is the attempt to understand the role of the Loma Prieta earthquake in the context of the earthquake 'machine' in northern California: as the latest event in a long history of shocks in the San...

1994, Water Data Report MI-93-1
Water resources data for the 1993 water year for Michigan consists of records of stage, discharge, and water quality of streams; stage and contents of lakes and reservoirs; and ground water levels. This report contains discharge records for 148 streamflowgaging stations; stage only records for 2 river-gaging stations and 7...

This paper briefly summarizes more than 470 measurements of local channel scour at bridge piers from 58 sites in 14 States. Relations between local scour and selected deterministic parameters are illustrated and discussed. Observed scour depths are compared with predicted values from two local scour prediction equations....

The U.S. Geological Survey is in the process of evaluating point-velocity current meters. As part of this evaluation process, a review of the literature pertaining to the testing of point-velocity current meters was conducted. A listing of current-meter testing found in the literature was compiled and is grouped according to...

Large areas of the Australian continent contain scattered saline lakes underlain by shallow saline groundwaters of regional extent and debated origin. The normative salt composition of subsurface pore fluids extracted by squeezing cores collected during deep drilling at Piangil West 2 in the central Murray Basin in southeastern Australia, and...

This report presents the irrigation water supply and demand data for 1976, 1980, and 1984 for 32 water districts in the western San Joaquin Valley, California. Data are provided for each water district or each of the three years if the data were available. The complete data base is given...

We develop theoretically a description of a possible subglacial drainage mechanism for glaciers and ice sheets moving over saturated, deformable till. The model is based on the plausible assumption that flow of water in a thin film at the ice-till interface is unstable to the formation of a channelized drainage...

Determination of the spatial and temporal distribution of precipitation in mountainous regions is critical for assessing the effects of climate variability on water resources in these regions. Potential effects of climate change on water resources in the Gunnison River basin of southwestern Colorado currently are being studied using a nested-model...

This paper examines the response of a flexible building during three earthquakes. The records from the building are long and contain low frequencies. The site frequency (0.33-0.38 Hz) is in proximity to the fundamental translational frequency (??? 0.45 Hz), which is closely coupled with the fundamental torsional frequency (???0.57 Hz)....

New 40Ar/39Ar age determinations on sanidine from the rhyolite of Alder Creek, California, indicate a 1.186 ±0.006 Ma age for the Cobb Mountain Normal-Polarity Subchron. The new age is statistically older (α = 0.05) than the previously reported K-Ar age (1.12 ±0.02 Ma) and...

A previously published Geological Survey report (Professional Paper 1409-H) describes ground-water flow and simulated development scenarios in Stagecoach Valley, Lyon and Storey Counties, Nevada. This study was done as part of the Survey's Great Basin Regional Aquifer-Systems Analysis program. Documentation of model input and output values used for analysis of...

1994, Book chapter, A century of avifaunal change in western North America (Studies in Avian Biology no. 15)
Only anecdotal information is available to assess whether populations of the 47 shorebird species that breed or winter west of the Rocky Mountains changed in size or distribution during the past century. Unregulated hunting from 1870 to 1927 reduced populations of several species, at least temporarily, and was a factor...

Many peak streamflow values used in flood analyses for desert areas are derived using the Manning equation. Data used in the equation are collected after the flow has subsided, and peak flow is thereby determined indirectly. Most measurement problems and associated errors in peak-flow determinations result from (1) channel erosion...

Stratigraphic and geomorphic relations, archeological data, and eight radiocarbon ages at five widely scattered localities in northeastern Colorado indicate that eolian sand was mobilized over broad areas within the past 1000 yr. The mobilization began after 1 ka, was episodic, and ended at...

We have determined oxygen and hydrogen isotope fractionation factors between alunite and water over a temperature range of 250-450??C by reacting synthetic natroalunite with 0.7 m K2SO4 -0.1 to 0.65 m H2SO4 solutions to produce K-rich alunite. From 88 to 95% alkali and isotope exchange were observed in most of...
