Determination of flood hydrographs for streams in South Carolina: Volume 1. Simulation of flood hydrographs for rural watersheds in South Carolina Determination of flood hydrographs for streams in South Carolina: Volume 1. Simulation of flood hydrographs for rural watersheds in South Carolina

A method is given for simulating a typical (average) flood hydrograph corresponding to a peak discharge of specific recurrence interval for ungaged rural basins having drainage areas less than 500 sq mi in South Carolina. Dimensionless hydrographs were developed for three regions on the basis of 188 storm events at 49 stations that represent a wide range of drainage area sizes and basin...

Ground-water withdrawals, water-level changes, land-surface subsidence, and ground-water quality in Fort Bend County, Texas, 1969-87 Ground-water withdrawals, water-level changes, land-surface subsidence, and ground-water quality in Fort Bend County, Texas, 1969-87

Fort Bend County, which has one of the fastest growing populations of all counties in the United States, is dependent entirely on ground water for public supply. Since 1969, at least 90 large-capacity wells have been drilled, of which 57 were public supply wells, 23 were irrigation wells, and 10 were industrial wells. All but seven of the new public-supply wells are located in the...

A finite-element model for simulation of two-dimensional steady-state ground-water flow in confined aquifers A finite-element model for simulation of two-dimensional steady-state ground-water flow in confined aquifers

A computer program based on the Galerkin finite-element method was developed to simulate two-dimensional steady-state ground-water flow in either isotropic or anisotropic confined aquifers. The program may also be used for unconfined aquifers of constant saturated thickness. Constant head, constant flux, and head-dependent flux boundary conditions can be specified in order to approximate...

Feeding chronology of juvenile piranhas, Pygocentrus notatus, in the Venezuelan llanos Feeding chronology of juvenile piranhas, Pygocentrus notatus, in the Venezuelan llanos

During the 1988 rainy season, I studied the 24 h feeding chronology of juvenile (40–68 mm standard length) piranhas, Pygocentrus notatus (Characidae: Serrasalminae) from a natural population inhabiting a small savanna stream in Apure State, Venezuela. Stomach contents analyses, supported by laboratory determinations of digestion rate, showed that these fish are primarily diurnal...

Toxicity of organic selenium in the diet to chinook salmon Toxicity of organic selenium in the diet to chinook salmon

The toxicity of two organoselenium diets was evaluated in 90- to 120-d partial life cycle tests with two life stages of chinook salmon (Oncorhynchus tshawytscha Walbaum). One of the diets contained fish meal made from high-selenium mosquitofish (Gambusia affinis Baird and Girard) collected from the selenium-laden San Luis Drain, California (here termed SLD diet) and the other contained...

Hydrology of the Arbuckle Mountains area, south-central Oklahoma Hydrology of the Arbuckle Mountains area, south-central Oklahoma

Rocks that make up the Arbuckle-Simpson aquifer crop out over ~500 mi2 in the Arbuckle Mountains province in south-central Oklahoma. The aquifer consists of limestone, dolomite, and sandstone of the Arbuckle and Simpson Groups of Late Cambrian to Middle Ordovician age and is about 5,000-9,000 ft thick. The rocks were subjected to intensive folding and faulting associated with major...

Water resources data, Georgia, water year 1989 Water resources data, Georgia, water year 1989

Water resources data for the 1989 water year for Georgia consists of records of stage, discharge, and water quality of streams; stage and contents of lakes and reservoirs; ground-water levels; and precipitation quality. This report contains discharge records of 118 gaging stations; stage for 27 gaging stations; stage and contents for 18 lakes and reservoirs; water quality for 105...
