George S. Outlaw, Jess D. Weaver
1996, Water-Resources Investigations Report 95-4293
Estimates of flow-duration and low-flow characteristics for the period of record at continuous-record streamflow stations are essential in hydrologic studies and water-resources management. This report provides flow-duration information, in the form of characteristics of the cumulative distribution function of the daily streamflow record, for 215 continuous-record streamflow stations. The report...
Recycling of nonmetallics
T.D. Kelly
1996, Natural Resources Research (5) 269-276
The first factor determining recyclability is the composition of the material itself. Metals, for example, can be reused with little or no loss in quality. Paper and rubber, by this criterion, are less recyclable. Each time paper is recycled, some cellulose fibers are broken. Shorter fibers can mean weaker paper...
Material flow analysis for an industry - A case study in packaging

1996, Geoarchaeology - An International Journal (11) 451-480
Prehistoric earthquake-induced liquefaction features occur in association with Native American occupation horizons in the New Madrid seismic zone. Age control of these liquefaction features, including sand-blow deposits, sand-blow craters, and sand dikes, can be accomplished by extensive sampling and flotation processing of datable materials as well as archaeobotanical analysis of...
Hydrologic feasibility of water-supply-development alternatives in Cape May County, New Jersey
F. J. Spitz
1996, Water-Resources Investigations Report 96-4041
Increasing public-supply withdrawals in Cape May County, New Jersey associated with increasing residential and seasonal tourist populations have led to regionally lowered ground-water levels, a reversal of ground-water flow directions toward onshore, and landward encroachment of saltwater in the shallow aquifer system. The three aquifers composing the shallow system are,...

James C. Blodgett, Karen R. Poeschel, Waite R. Osterkamp
1996, Open-File Report 96-144
Studies of Mount Shasta indicate that eruptive activity has occurred, on the average, once every 800 years. Debris flows and deposits of non- eruptive origin, in addition to those associated with eruptive activity (lava flows, pyroclastic flows, and ash fall), inundate the fans and channels and can endanger people or...

Scour at bridge sites in Delaware, Maryland, and Virginia
Donald C. Hayes
1996, Water-Resources Investigations Report 96-4089
Scour data were obtained from discharge measure- ments to develop and evaluate the reliability of constriction-scour and local-scour equations for rivers in Delaware, Maryland, and Virginia. No independent constriction-scour or local-scour equations were developed from the data because no significant relation was deter-mined between measured scour and streamflow, streambed, and...
