Relationship of suspended sediment to streamflow in the Green River Basin, Wyoming
B. H. Ringen
1984, Water-Resources Investigations Report 84-4026
The relation of suspended-sediment concentration to water discharge was computed using regression analysis for 33 stations and 2 miscellaneous sites in the Green River basin, Wyoming. These relations show that suspended-sediment concentrations vary in direct proportion to streamflow. The number of coincident instantaneous suspended-sediment concentration and water-discharge values available for...
Selenium concentrations in waters tributary to and in the vicinity of the Kesterson National Wildlife Refuge, Fresno and Merced counties, California
T. S. Presser, Ivan Barnes
1984, Water-Resources Investigations Report 84-4122
Analyses were made for selenium in waters and other materials of the Kesterson National Wildlife Refuge. Analyses were also made of source agricultural drainage waters from the San Luis Drain discharged into the refuge, and surrounding irrigation supply and return waters. Selenium concentrations range from 140 to 1 ,400 micrograms...
Description and hydrogeologic implications of cored sedimentary material from the 1975 drilling program at the radioactive waste management complex, Idaho
C.T. Rightmire
1984, Water-Resources Investigations Report 84-4071
Samples of sedimentary material from interbeds between basalt flows and from fractures in the flows, taken from two drill cores at the Radioactive Waste Management Complex at the Idaho National Engineering Laboratory were analyzed for (1) particle-size dribution, (2) bulk mineralogy, (3) clay mineralogy, (4) cation-exchange capacity, and (5) carbonate...
Water use in Arkansas, 1981
A.P. Hall, T.W. Holland
1984, Water-Resources Investigations Report 84-4070
Water use and consumption data for 1981 are presented by county and source. Use-data are presented by category for each county. Total water use, excluding wildlife impoundments, was 32,970 million gallons per day, which was 19 percent less than in 1980; consumption was 4,610 million gallons per day. Ground water...
Nutrient and detritus transport in the Apalachicola River, Florida
Harold C. Mattraw, John F. Elder
1984, Water Supply Paper 2196-C
The Apalachicola River in northwest Florida flows 172 kilometers southward from Jim Woodruff Dam near the Florida-Georgia border to Apalachicola Bay on the Gulf of Mexico. The basin is composed of two 3,100-squarekilometer subbasins, the Chipola and the Apalachicola. The Apalachicola subbasin includes a 454-square-kilometer bottom-land hardwood flood plain that...
Finite-element simulation of ground-water flow in the vicinity of Yucca Mountain, Nevada-California
J.B. Czarnecki, R. K. Waddell
1984, Water-Resources Investigations Report 84-4349
A finite-element model of the groundwater flow system in the vicinity of Yucca Mountain at the Nevada Test Site was developed using parameter estimation techniques. The model simulated steady-state ground-water flow occurring in tuffaceous, volcanic , and carbonate rocks, and alluvial aquifers. Hydraulic gradients in the modeled area range from...
The hydrogeologic framework for the southeastern Coastal Plain aquifer system of the United States
R.A. Renken
1984, Water-Resources Investigations Report 84-4243
Tertiary and Cretaceous age sand aquifers of the southeastern United States Coastal Plain constitute a distinct multistate hydrogeologic regime informally defined as the southeastern sand aquifer. Seven regional hydrogeologic units are defined; four regional aquifer units and three regional confining beds. Sand aquifers of this system consist of quartzose, feldspathic,...
Sandstone units of the Lee Formation and related strata in eastern Kentucky
Charles L. Rice
1984, Professional Paper 1151-G
Most of the Cumberland Plateau region of southeastern Kentucky is underlain by thick sequences of quartzose sandstone which are assigned for the most part to the Lee Formation. Much new information has been gathered about the Lee and related strata as a result of the cooperative mapping program of the...
Climatic data for Mirror Lake, West Thornton, New Hampshire, 1981-82
A.M. Sturrock, D.C. Buso, G.M. Bieber, L.G. Engelbrecht, T. C. Winter
1984, Open-File Report 84-816
Research on the hydrology of Mirror Lake, (north-central) New Hampshire includes study of evaporation. Presented here are those climatic data needed for energy-budget and mass-transfer studies, including: temperature of lake water surface, dry-bulb and wet-bulb air temperatures, wind speed, precipitation and solar radiation. Data are collected at raft and land...
Recharge and discharge areas of the Floridan Aquifer in the St. Johns River Water Management District and vicinity, Florida
G. G. Phelps
1984, Water-Resources Investigations Report 82-4058
The Floridan aquifer is the principal source of most of the freshwater used in the St. Johns River Water Management District. An important step in managing water resources is the delineation of recharge and discharge areas. Geohydrologic factors to be considered when delineating recharge and discharge areas include: altitude and...
