Review of mechanisms, methods, and theory for determining recharge to shallow aquifers in North Dakota
W.F. Horak
1988, Water-Resources Investigations Report 88-4122
Effective management of ground-water resources requires knowledge of all components of the water budget for the aquifer of interest. Efforts to simulate ground-water flow prior to development and the effects of proposed pumping in several of North Dakota's shallow glacial aquifers have been hindered by the lack of reliable estimates...
Hydrogeology and flow of water in a sand and gravel aquifer contaminated by wood-preserving compounds, Pensacola, Florida
B.J. Franks
1988, Water-Resources Investigations Report 87-4260
The sand and gravel aquifer in southern Escambia County, Florida , is a typical surficial aquifer composed of quartz sands and gravels interbedded locally with silts and clays.

An experiment in representative ground-water sampling for water- quality analysis
T.L. Huntzinger, L.E. Stullken
1988, Water-Resources Investigations Report 88-4178
Obtaining a sample of groundwater that accurately represents the concentration of a chemical constituent in an aquifer is an important aspect of groundwater-quality studies. Varying aquifer and constituent properties may cause chemical constituents to move within selectively separate parts of the aquifer. An experiment was conducted in an agricultural region...

1988, Water-Resources Investigations Report 87-4253
Analysis of water samples from Lexington Reservoir and Los Gatos Creek upstream from the reservoir from June 1978 through September 1980 showed that water generally met water-quality objectives identified by California Regional Water Quality Control Board, San Francisco Bay Region. Water-temperature profiles show that Lexington Reservoir is a warm monomictic...
Discharge ratings for control structures at McHenry Dam on the Fox River, Illinois
G. G. Fisk
1988, Water-Resources Investigations Report 87-4226
Twenty-three measurement of discharge were used to determine discharge ratings for the five adjustable sluice gates, spillway and fish ladder at McHenry Dam on the Fox River in Illinois. Discharge ratings were determined for free weir, free orifice, and submerged orifice flow regimes. Hydraulic conditions that identify flow regimes at...
Hydrogeology, aquifer characteristics, and ground-water flow of the surficial aquifer system, Broward County, Florida
J.E. Fish
1988, Water-Resources Investigations Report 87-4034
The surficial aquifer system, in which an unconfined groundwater flow system exists, comprises the sediments from land surface to the intermediate confining unit (formerly called the Floridan aquiclude) in Broward County, Florida. These sediments have hydraulic conductivities that range more than seven orders of magnitude from about 0.001 ft/d to...
Techniques for estimating the magnitude and frequency of floods in Minnesota
J.E. Jacques, D. L. Lorenz
1988, Water-Resources Investigations Report 87-4170
Log-Pearson type III flood-frequency analyses were made of annual series peak-flow records from 246 gaging stations on unregulated streams in Minnesota having watersheds ranging in area from 0.08 to 2,520 square miles. These flood discharges were related to watershed and climatic characteristics by using multiple-regression techniques. On the basis of...
Preimpoundment hydrologic conditions in the Swatara Creek (1981-84) and estimated postimpoundment water quality in and downstream from the planned Swatara State Park Reservoir, Lebanon and Schuylkill counties, Pennsylvania

A digital simulation of the glacial-aquifer system in Sanborn and parts of Beadle, Miner, Hanson, Davison, and Jerauld counties, South Dakota
P.J. Emmons
1988, Water-Resources Investigations Report 87-4082
The drought in South Dakota from 1974-76 and the near drought conditions in 1980-81 have resulted in increased demands on the groundwater resources within many of the irrigated areas of the James River basin in eastern South Dakota. These increases in demand for irrigation water from the glacial aquifer system,...

Douglas G. Emerson
1988, Water-Resources Investigations Report 88-4038
Hydrologric data were used to determine the premining surface-water conditions in two small basins in the Fort Union coal region of Montana and North Dakota. The two streams. Hay Creek and West Branch Antelope Creek, are ephemeral. Most of the volume and peak discharges are due to snowmelt runoff. Little...
