Beach-ridge development and lake-level variation in southern Lake Michigan
T.A. Thompson
1992, Sedimentary Geology (80) 305-318
The most accurate source of information on lake-level fluctuations in the Great Lakes is the historical record from lake-level gauges. Although it can be semiquantitatively extended back into the late 1700's, the historical record is too short to recognize long-term patterns of lake-level behavior. To extend the historical record, information...

Glenn Borchardt, Sue E. Hirschfeld, James J. Lienkaemper, Patrick H. McClellan, Patrick L. Williams, Ivan G. Wong, editor(s)
1992, Conference Paper, Proceedings of the second conference on earthquake hazards in the eastern San Francisco Bay area: Special publication 113
The Hayward fault, thought a likely source of large earthquakes in the next few decades, has generated two large historic earthquakes (about magnitude 7), one in 1836 and another in 1868. We know little about the 1836 event, but the 1868 event had a surface rupture extending 41 km along...
Configuration of the base of the Edwards-Trinity aquifer system and hydrogeology of the underlying pre-Cretaceous rocks, west-central Texas
Rene A. Barker, Ann F. Ardis
1992, Water-Resources Investigations Report 91-4071
The Edwards-Trinity aquifer system is underlain by an extensive complex of rocks, ranging from Late Cambrian through Late Triassic in age, that are typically about 10 to perhaps 1,000 times less permeable than those composing the aquifer system. The Cretaceous rocks of the aquifer system are separated from the pre-Cretaceous...

1992, Professional Paper 1551-F
During the earthquake, a total land area of about 4,300 km2 was shaken with seismic intensities that can cause significant damage to structures. The area of the Marina District of San Francisco is only 4.0 km2--less than 0.1 percent of the area most strongly affected by the earthquake--but its significance...
Streamflow gains and losses in the Snake River and ground-water budgets for the Snake River Plain, Idaho and eastern Oregon
L.C. Kjelstrom
1992, Open-File Report 90-172
The Snake River is the regional drain for streams and aquifers in the Snake River basin upstream from Weiser, Idaho. The interaction between the river and ground water was quantified as streamflow gains from and losses to the aquifers. Upstream from Milner, Idaho, the Snake River both gains and loses...

P.R. Bowman
1992, Open-File Report 92-500
Hydrologic data for a study of pre-lllinoian glacial till were collected during the 1991 water year at a site in Linn County, east-central Iowa. A hydrologic-data-collection network, consisting of a meteorological station, 22 observation wells, and a water-quality minimonitor, was installed at the site to investigate the hydraulic properties of...
