Real-time rainfall measurement in the City of Charlotte and Mecklenburg County, North Carolina Real-time rainfall measurement in the City of Charlotte and Mecklenburg County, North Carolina
The U.S. Geological Survey (USGS) has measured rainfall at various locations in Mecklenburg County, North Carolina, since 1963. Between 1992 and 1997, the USGS, in cooperation with Charlotte Stormwater Services, installed 43 raingages throughout Mecklengburg County and adjoining counties. These 43 raingages, combined with three previously installed gages, compose a data-collection...

Woody debris decomposition in the Atchafalaya River Basin of Louisiana following hurricane disturbance Woody debris decomposition in the Atchafalaya River Basin of Louisiana following hurricane disturbance
The contribution of woody debris to some biogeochemical functions of forested wetlands was examined in the Atchafalaya River Basin in Louisiana following disturbance by Hurricane Andrew. Woody debris decomposition processes were characterized in terms of mass, C, N, and P dynamics. These were compared between different diameters of debris, areas recieving different intensities of...

Polychlorinated dibenzo-p-dioxins, dibenzofurans, biphenyls and 2,3,7,8-tetrachlorodibenzo-p-dioxin equivalents in fishes from Saginaw Bay, Michigan Polychlorinated dibenzo-p-dioxins, dibenzofurans, biphenyls and 2,3,7,8-tetrachlorodibenzo-p-dioxin equivalents in fishes from Saginaw Bay, Michigan
Concentrations of polychlorinated biphenyls (PCBs), polychlorinated dibenzo-p-dioxins (PCDDs), polychlorinated dibenzofurans (PCDFs), polychlorinated naphthalenes (PCNs), polychlorinated dibenzothiophenes (PCDTs), and 2,3,7,8-tetrachlo-rodibenzo-p-dioxin (2,3,7,8-TCDD) equivalents were measured in composite samples of forage fishes and several sizes of walleyes (Stizostedion vitreum) and...

Organochlorine contaminants in double-crested cormorants from Green Bay, Wisconsin: II. Effects of an extract derived from cormorant eggs on the chicken embryo Organochlorine contaminants in double-crested cormorants from Green Bay, Wisconsin: II. Effects of an extract derived from cormorant eggs on the chicken embryo
White Leghorn chicken (Gallus domesticus) eggs were injected prior to incubation with one of four concentrations (0.001, 0.01, 0.1, and 1.0 egg-equivalent) of an extract derived from 1,000 double-crested cormorant (Phalacrocorax auritus) eggs collected at Spider Island adjacent to Green Bay in Lake Michigan. One egg-equivalent corresponded to the concentration of contaminants present in...

The use of semipermeable membrane devices (SPMDs) to concentrate inducers of fish hepatic mixed function oxygenase (MFO): Chapter 12 The use of semipermeable membrane devices (SPMDs) to concentrate inducers of fish hepatic mixed function oxygenase (MFO): Chapter 12
Semipermeable membrane devices (SPMDs) are sampling and concentrating devices comprised of a thin polyethylene membrane containing a small quantity of triolein. They have previously been used to sample air, water and sediments and have concentrated fish tainting compounds from pulp mill effluents. The ability to induce mixed function oxygenases (MFOs) is a property of a variety of...

Effect of hydrologic management on marsh surface sediment deposition in coastal Louisiana Effect of hydrologic management on marsh surface sediment deposition in coastal Louisiana
High rates of coastal land loss in Louisiana have prompted efforts to maintain or restore coastal wetland habitats, and structural management of marsh hydrology is one of a number of approaches that has been adopted. The aim of this study was to determine the effect of hydrologic management measures on marsh-surface sediment deposition in the Mississippi deltaic plain. Four impoundments...

Use of particle tracking to improve numerical model calibration and to analyze ground-water flow and contaminant migration, Massachusetts Military Reservation, western Cape Cod, Massachusetts Use of particle tracking to improve numerical model calibration and to analyze ground-water flow and contaminant migration, Massachusetts Military Reservation, western Cape Cod, Massachusetts
A steady-state, three-dimensional flow model coupled with a particle-tracking algorithm was developed to assess the complex interaction of hydrogeologic conditions affecting ground-water flow and contaminant transport--including aquifer heterogeneities, hydrologic boundaries such as ponds and streams, ground-water withdrawals, and aquifer recharge to characterize the migration of...

Summary of surface-water hydrologic data for the Houston metropolitan area, Texas, water years 1964-89 Summary of surface-water hydrologic data for the Houston metropolitan area, Texas, water years 1964-89
The study area, a metropolitan area in southeast Texas about 45 miles north of the Gulf of Mexico, has been undergoing extensive urban development since the 1950s. The Houston Urban Runoff Program was begun by the U.S. Geological Survey in water year 1964 to define the magnitude and frequency of flood peaks, to determine the impact of continuing urban development on surface-water...
