Application of acoustic velocity meters for gaging discharge of three low-velocity tidal streams in the St. Johns River basin, northeast Florida
J. V. Sloat, W. S. Gain
1995, Water-Resources Investigations Report 95-4230
Index-velocity data collected with acoustic velocity meters, stage data, and cross-sectional area data were used to calculate discharge at three low-velocity, tidal streamflow stations in north-east Florida. Discharge at three streamflow stations was computed as the product of the channel cross-sectional area and the mean velocity as determined from an...
Quality of surface water and ground water in the proposed artificial-recharge project area, Rillito Creek basin, Tucson, Arizona, 1994
Saeid Tadayon
1995, Water-Resources Investigations Report 95-4270
Controlled artificial recharge of surface runoff is being considered as a water-management technique to address the problem of ground-water overdraft. The planned use of recharge facilities in urban areas has caused concern about the quality of urban runoff to be recharged and the potential for ground-water contamination. The proposed recharge...

L.C. Kjelstrom
1995, Water-Resources Investigations Report 95-4228
The U.S. Environmental Protection Agency requires information on the volume and quality of urban storm-water runoff to apply for a permit to discharge this water into the Boise River under the National Pollutant Discharge Elimination System Program. Concentrations of selected chemical constituents in storm runoff were determined from samples collected...
Analysis of streamflow characteristics for streams on the island of Tutuila, American Samoa
Michael F. Wong
1995, Water-Resources Investigations Report 95-4185
Several methods for estimating streamflow characteristics for low and peak flows for streams on Tutuila, American Samoa are presented. These methods, derived from frequency, flow-duration, and regression analyses, allow the user to compute estimates for the 7-day low flow with 2-year and 10-year recurrence intervals; the median flow; the mean...

1995, Open-File Report 95-279
The implementation of design guidelines for the National Water-Quality Assessment (NAWQA) Program has resulted in the development of new sampling procedures and the modification of existing procedures commonly used in the Water Resources Division of the U.S. Geological Survey. The Georgia-Florida Coastal Plain (GAFL) study unit began the intensive data...
Simulation of stage and the the hydrologic budget of Devils Lake, Sauk County, Wisconsin
J. T. Krohelski, W. G. Batten
1995, Open-File Report 94-348
Water clarity of Devils Lake, in the Driftless Area of southwestern Wisconsin, has been decreasing because of blue-green algal blooms. An understanding of the hydrology of Devils Lake is needed to develop a mitigation plan to reduce phosphorus input. A model was developed to test the current understanding of the...

M. D. Dettinger, J. R. Harrill, D. L. Schmidt, J.W. Hess
1995, Water-Resources Investigations Report 91-4146
In 1985, the State of Nevada entered into a cooperative effort with the U.S. Department of the Interior to study and test the State's carbonate- rock aquifers. The studies were focused on southern Nevada and were intended to address the following concerns: Where is water potentially available in the aquifers?;...

The Black Mesa monitoring program is designed to document long-term effects of ground-water pumping from the N aquifer by industrial and municipal users. The N aquifer is the major source of water in the 5,400-square-mile Black Mesa area, and the ground water occurs under confined and unconfined conditions. Monitoring activities...
Geohydrology and simulation of ground-water flow near Los Alamos, north-central New Mexico
P. F. Frenzel
1995, Water-Resources Investigations Report 95-4091
An existing model was modified in recognition of new geohydrologic interpretations and adjusted to simulate hydrographs in well fields in the Los Alamos area. Hydraulic-head drawdowns at the Buckman well field resulting from two projected ground-water-withdrawal alternatives were estimated with the modified model. The Chaquehui formation (informal usage)...

Evaluation of ground-water flow and hydrologic budget for Lake Five-O, a seepage lake in northwestern Florida
J. W. Grubbs
1995, Water-Resources Investigations Report 94-4145
Temporal and spatial distributions of ground-water inflow to, and leakage from Lake Five-O, a softwater, seepage lake in northwestern Florida, were evaluated using hydrologic data and simulation models of the shallow ground-water system adjacent to the lake. The simulation models indicate that ground-water inflow to the lake and leakage from...
Water Budget for the Island of Kauai, Hawaii
Patricia J. Shade
1995, Water-Resources Investigations Report 95-4128
A geographic information system model was created to calculate a monthly water budget for the island of Kauai. Ground-water recharge is the residual component of a monthly water budget calculated using long-term average rainfall, streamflow, and pan-evaporation data, applied irrigation-water estimates, and soil characteristics. The water-budget components are defined seasonally,...
The use of three-parameter rating table lookup programs, RDRAT and PARM3, in hydraulic flow models
C.L. Sanders Jr.
1995, Water-Resources Investigations Report 95-4090
Subroutines RDRAT and PARM3 enable computer programs such as the BRANCH open-channel unsteady-flow model to route flows through or over combinations of critical-flow sections, culverts, bridges, road- overflow sections, fixed spillways, and(or) dams. The subroutines also obstruct upstream flow to simulate operation of flapper-type tide gates. A multiplier can be...
The distribution of bromide in water in the Floridan aquifer system, Duval County, northeastern Florida
E. R. German, G.F. Taylor
1995, Water-Resources Investigations Report 94-4154
Although Duval County, Florida, has ample ground-water resources for public supply, the potential exists for a problem with excessive disinfectant by-products. These disinfectant by-products result from the treatment of raw water containing low concentrations of bromide and naturally occurring organic compounds. Because of this potential problem, the relation of bromide...
