National Water Quality Assessment Program; the Santee Basin and coastal drainage, North Carolina and South Carolina National Water Quality Assessment Program; the Santee Basin and coastal drainage, North Carolina and South Carolina

In 1991, the U.S. Geological Survey (USGS), U.S. Department of the Interior, began a National Water-Quality Assessment Program (NAWQA). The long-term goals of NAWQA are to describe the status of and trends in the quality of a large representative part of the Nation's surface- and ground-water resources and to identify all the major factors that affect the quality of these resources. In...

Factors affecting accuracy of slope-area discharge determination of the September 1992 flood in Raven Fork, Western North Carolina Factors affecting accuracy of slope-area discharge determination of the September 1992 flood in Raven Fork, Western North Carolina

For the flood of September 10, 1992, in Raven Fork, Swain County, North Carolina, a peak discharge of 460 cubic meters per second was computed by using the slope-area method. Accuracy of this determination depends on suitability of the selected reach and, in particular, selection of Manning's roughness coefficients, interpretation of the high-water marks, number and placement of cross...

Polychlorinated biphenyl congeners in emergent mayflies from the upper Mississippi River Polychlorinated biphenyl congeners in emergent mayflies from the upper Mississippi River

We determined polychlorinated biphenyls (pcbs) in emergent mayflies (hexagenia bilineata) from a 1250-km reach of the upper mississippi river (UMR). Total pcb concentrations (sum of 125 congeners) ranged from 0.21 To 4.1 Mu g/g of dry weight (1.2-29 mu g/g of lipid weight). Concentrations were highest in pools near the twin cities and the quad cities metropolitan areas. Longitudinal...

Prospects for improving the salt tolerance of forest trees: A review Prospects for improving the salt tolerance of forest trees: A review

Three major themes related to the improvement of salt tolerance in forest tree species are examined. First, evidence demonstrating that substantial intraspecific variation in salt tolerance exists in many species is presented. This evidence is important because it suggests that efforts to improve salt tolerance through conventional plant breeding techniques are justified. Second, the...
