Proceedings of Workshop XIV: earthquake hazards of the Puget Sound region, Washington
Robert S. Crosson, Muriel L. Jacobson (compiler)
James C. Yount, editor(s)
1983, Open-File Report 83-19
This conference, the fourteenth in a series sponsored by the Earthquake Hazards Reduction Program, was held October 13-15, 1980 at Lake Wilderness, Washington. The stated purpose of the conference was to assess progress and the state of knowledge of earthquake hazards in the Puget Sound region of Washington. The small size of the group...
Potentiometric surface of the Floridan Aquifer and its use in management of water resources, St. Johns River Water Management District, Florida
Harry George Rodis, D.A. Munch
1983, Water-Resources Investigations Report 83-4176
The Floridan aquifer supplies most of the fresh groundwater for municipal, industrial, and agricultural uses within the 12,400 sq mi St. Johns River Water Management District. Because of the growing demand for water and the variation in rainfall, resource managers need timely information on short-term and long-term changes in the...
Connector well experiment to recharge the Floridan aquifer, east Orange County, Florida
Peter W. Bush
1983, Water Supply Paper 2210
An experimental connector well, screened in the shallow sand aquifer, finished with open hole in the Floridan aquifer and cased through the confining layer between the two aquifers, was drilled in east Orange County, Fla., to obtain information on the nature and function of the shallow aquifer as related to...
Analysis and computer simulation of stream-aquifer hydrology, Arkansas River Valley, southwestern Kansas
R.A. Barker, C. G. Sauer, L. E. Dunlap
1983, Water Supply Paper 2200
A study was made, in cooperation with the Division of Water Resources, Kansas State Board of Agriculture, to determine geohydrologic conditions underlying nearly 110,000 acres of the Arkansas River Valley between the Colorado-Kansas State line and the Bear Creek Fault zone in southwestern Kansas. The Arkansas River meanders atop and...
Evidence of tectonic stability along the middle Columbia River, Washington, in Quaternary time
William Henry Hays, Robert L. Schuster
1983, Open-File Report 83-365
Observations of outcrops and Pleistocene-age surfaces along the Columbia River, between Priest Rapids Dam and Richland, Washington, provide evidence for recent tectonic stability that may be significant to planning of earthquake-sensitive engineered structures in the vicinity. Apparent continuity of layering in the Yakima Basalt (Miocene), Ringold Formation (Pliocene), and calcrete...
A two-dimensional, finite-difference model of the high plains aquifer in southern South Dakota
K.E. Kolm, H. L. Case III
1983, Water-Resources Investigations Report 83-4175
The High Plains aquifer is the principal source of water for irrigation, industry, municipalities, and domestic use in south-central South Dakota. The aquifer, composed of upper sandstone units of the Arikaree Formation, and the overlying Ogallala and Sand Hills Formations, was simulated using a two-dimensional, finite-difference computer model. The maximum...
