Water-quality characteristics of streams in the Treyburn Development area of Falls Lake watershed, North Carolina, 1988-93 Water-quality characteristics of streams in the Treyburn Development area of Falls Lake watershed, North Carolina, 1988-93
Treyburn is a 5,400 acre planned, mixed-use community located in the Falls Lake watershed in the upper Neuse River Basin of North Carolina. From February 1988 through 1993, hydrologic-data were collected at 17 study sites in or near the Treyburn development to compare the effects of varying types of land-use development on the water-quality of streams flowing in or near the development...

Technique for estimating the 2- to 500-year flood discharges on unregulated streams in rural Missouri Technique for estimating the 2- to 500-year flood discharges on unregulated streams in rural Missouri
A generalized least-squares regression technique was used to relate the 2- to 500-year flood discharges from 278 selected streamflow-gaging stations to statistically significant basin characteristics. The regression relations (estimating equations) were defined for three hydrologic regions (I, II, and III) in rural Missouri. Ordinary least-squares regression analyses indicate that...

Monitoring flooding in coastal wetlands by using radar imagery and ground-based measurements Monitoring flooding in coastal wetlands by using radar imagery and ground-based measurements
Satellite radar was used in a Florida Juncus roemerianus marsh to map tidal flooding, a critical control of coastal vegetation distribution. Radar images taken during a time of near-continuous recordings of ground-based hydrology measurements directly linked marsh flooding to lowered radar returns and indicated a negative covariation between flood frequency and radar return. Flood-extent...

Geology and hydrology of the Edwards Aquifer in the San Antonio area, Texas Geology and hydrology of the Edwards Aquifer in the San Antonio area, Texas
The Edwards aquifer, which is the sole source of water for the city of San Antonio, is one of the most permeable and productive carbonate aquifers in the United States. The aquifer is composed of extensively faulted, fractured, and cavernous limestone and dolomite of Early Cretaceous age lying within the Balcones fault zone a series of normal en echelon strike faults that separate the...

Marine turtles in the Southeast Marine turtles in the Southeast
Five species of marine turtles frequent the beaches and offshore waters of the southeastern United States: loggerhead (Caretta caretta), green (Chelonia mydas), Kemp's ridley (Lepidochelys kempii), leatherback (Dermochelys coriacea), and hawksbill (Eretmochelys imbricata). All five are reported to nest, but only the loggerhead and green turtle do so in substantial numbers. Most nesting...

Comparison of methods for conducting marine and estuarine sediment porewater toxicity tests—extraction, storage, and handling techniques Comparison of methods for conducting marine and estuarine sediment porewater toxicity tests—extraction, storage, and handling techniques
A series of studies was conducted to compare different porewater extraction techniques and to evaluate the effects of sediment and porewater storage conditions on the toxicity of pore water, using assays with the sea urchin Arbacia punctulata. If care is taken in the selection of materials, several different porewater extraction techniques (pressurized squeezing, centrifugation, vacuum)...

Formation and regression of the corpus luteum of the American alligator Formation and regression of the corpus luteum of the American alligator
Luteal morphology of the American alligator is unique when compared to other reptiles but is similar to that of its phylogenetic relatives, the birds. The theca is extensively hypertrophied, but the granulosa never fills the cavity formed following the ovulation of the ovum. The formation of the corpus luteum (CL) is correlated with elevated plasma progesterone concentrations, which...
