Design, operation, and monitoring capability of an experimental artificial-recharge facility at East Meadow, Long Island, New York
B.J. Schneider, E. T. Oaksford
1986, Water-Resources Investigations Report 84-4321
Artificial recharge with tertiary-treated sewage is being tested at East Meadow to evaluate the physical and chemical effects on the groundwater system. The recharge facility contains 11 recharge basins and 5 injection wells and is designed to accept 4 million gallons of reclaimed water per day. Of the 11 basins,...
Red-Sea rift magmatism near Al Lith, Kingdom of Saudi Arabia
J.S. Pallister
1986, Open-File Report 86-565
A newly recognized Tertiary dike complex and comagmatic volcanic rocks exposed on the central Saudi Arabian coastal plain record early stages of magmatism related to Red Sea rifting. Intrusive and stratigraphic relationships, and new potassium-argon dating indicate episodic magmatism from about 30 Ma to the present. Additional stratigraphic and radiometric...
Volcanic rocks
1986, Report
Volcanoes have contributed significantly to the formation of the surface of our planet. Volcanism produced the crust we live on and most of the air we breathe. Often the remnants of an eruption are as revealing as the eruption itself, for they tell us many things about the eruption. Included...
Landslides
National Geophysical Data Center
1986, Report
The slopes above streams and rivers are subjected to a variety of processes that cause them to recede and retreat from the river or stream channel. These processes, collectively called mass wasting, can be classified according to rapidity of movement and according to the type of materials that are transported. Gravity is the...
Earthquakes
National Geophysical Data Center
1986, Report
An earthquake is the motion or trembling of the ground produced by sudden displacement of rock in the Earth's crust. Earthquakes result from crustal strain, volcanism, landslides, and collapse of caverns. Stress accumulates in response to tectonic forces until it exceeds the strength of the rock. The rock then breaks along a preexisting...
On tide-induced Lagrangian residual current and residual transport: 1. Lagrangian residual current
Shizuo Feng, Ralph T. Cheng, Xi Pangen
1986, Water Resources Research (22) 1623-1634
Residual currents in tidal estuaries and coastal embayments have been recognized as fundamental factors which affect the long-term transport processes. It has been pointed out by previous studies that it is more relevant to use a Lagrangian mean velocity than an Eulerian mean velocity to determine the movements of water...
Arctic National Wildlife Refuge land cover mapping project user's guide
Carl J. Markon
1986, Report
Section 1002 of the Alaska National Interest Lands Conservation Act of 1980 (ANILCA, 1980) requires the Secretary of Interior to conduct a continuing study of fish, wildlife, and habitats on the coastal plain of the Arctic National Wildlife Refuge (ANWR). Included in this study is a determination of the extent, location, and carrying capacity of...
On tide-induced Lagrangian residual current and residual transport: 2. Residual transport with application in south San Francisco Bay, California
Shizuo Feng, Ralph T. Cheng, Xi Pangen
1986, Water Resources Research (22) 1635-1646
The transports of solutes and other tracers are fundamental to estuarine processes. The apparent transport mechanisms are convection by tidal current and current-induced shear effect dispersion for processes which take place in a time period of the order of a tidal cycle. However, as emphasis is shifted toward the effects...
Evaluation of Alaskan wetlands for waterfowl
Calvin J. Lensink, Dirk V. Derksen
1986, Conference Paper, Alaska: Regional wetland functions: Proceedings of a workshop held at Anchorage, Alaska, May 28-29, 1986
Few studies have focused specifically on use of Alaskan wetlands by waterfowl. However, substantial information on the values of wetlands is available from studies on individual species or that were conducted for other purposes. Most investigators have found it most effective to classify habitat use on the basis of observed...
Hydrology of carbonate aquifers in southwestern Linn County and adjacent parts of Benton, Iowa, and Johnson Counties, Iowa
Kenneth Wahl, Bill J. Bunker
1986, Water Supply Bulletin 15
Groundwater is the major source of water in Linn County and the surrounding area. Approximately 90 percent of the groundwater production is from Silurian, Devonian, and Quaternary aquifers. The Silurian and Devonian aquifers consist of limestone and dolomite with minor shale beds, which have a regional dip to the southwest of...
Geology and geochemistry of the Deer Trail Pb-Zn-Ag-Cu manto deposits, Marysvale District, west-central Utah
D.W. Beaty, C. G. Cunningham, R.O. Rye, T. A. Steven, E. Gonzalez- Urien
1986, Economic Geology (81) 1932-1952
Strata-bound sulphide replacement bodies in the Deer Trail mine are sinuous pipes in carbonate beds, approximately localized by an anticlinal axis, and radiate from a fault across the lower part of the Permian Toroweap formation. Indistinct sericitic envelopes provide a K/Ar age of 14 m.y., correlative with barren, altered volcanic...
