Kenneth R. Watts, Lloyd E. Stullken
1985, Open-File Report 81-344
The High Plains aquifer in Kansas is part of a regional system that extends from South Dakota to Texas. In Kansas, the aquifer underlies an area of 30,900 square miles in the western and south-central part. The aquifer is a hydraulically connected aggregation of unconsolidated water-bearing deposits. The High Plains...

Results of the US Geological Survey's second International Interlaboratory Analytical Comparison Study; Standard Reference Water Samples M-86 (major constituents), T-87 (trace constituents), and P-5 (precipitation snowmelt)
V.J. Janzer
1985, Water-Resources Investigations Report 85-4049
The U.S. Geological Survey began an interlaboratory testing program of standard-reference water samples in 1962. Program objectives have been to provide a means for participating anaytical laboratories to: (1) Identify analytical problems, (2) ascertain the accuracy and precision of common water analyses and analytical methods, and (3) obtain reference samples...

Evaluation of techniques for mapping land and crops irrigated by center pivots from computer-enhanced Landsat imagery in part of the James River basin near Huron, South Dakota
K.E. Kolm
1985, Water-Resources Investigations Report 85-4021
The objective of this study was to evaluate remote sensing techniques for mapping irrigated crop types and acreages in part of the James River basin of South Dakota, using Landsat imagery. The results demonstrated that a subtraction (band 7 minus band 4) method was best for identifying the location of...

Determination of roughness coefficients for streams in Colorado
R.D. Jarrett
1985, Water-Resources Investigations Report 85-4004
Most hydraulic calculations of flow in channels and overbank areas require an evaluation of flow resistance, generally expressed as Manning 's roughness coefficient. The degree of roughness depends on many factors. The report summarizes and relates several methods of estimating roughness and presents additional channel-roughness verification data on higher-gradient streams...
Water resources of Aurora and Jerauld Counties, South Dakota
L.J. Hamilton
1985, Water-Resources Investigations Report 84-4030
Large quantities of slightly saline ground water are available for future water requirements in Aurora and Jerauld Counties, 1 ,236 square miles of glaciated, till-covered hills and plains in southeastern South Dakota. More than one million acre-feet of ground water is stored in five major glacial aquifers, outwash sand and...
Contributions of suspended sediment from highway construction and other land uses to the Olentangy River, Columbus, Ohio
D.R. Helsel
1985, Water-Resources Investigations Report 84-4336
Highway construction within the Olentangy River flood plain in Columbus, Ohio, was projected to be a large source of suspended sediment to the river system. A monitoring program was begun by the U.S. Geological Survey in 1978 to quantify the implacts of construction process. Sediment information was collected daily at...
Cost effectiveness of the stream-gaging program in Louisiana
R.A. Herbert, D.D. Carlson
1985, Water-Resources Investigations Report 85-4044
This report documents the results of a study of the cost effectiveness of the stream-gaging program in Louisiana. Data uses and funding sources were identified for the 68 continuous-record stream gages currently (1984) in operation with a budget of $408,700. Three stream gages have uses specific to a short-term study...

An evaluation of the crest-stage gage program in Louisiana
R.A. Herbert, D.D. Carlson, G.J. Wiche
1985, Water-Resources Investigations Report 84-4204
The crest-stage gage program in Louisiana was evaluated to determine if the data were adequate for use in developing regional flood-frequency equations and to determine if any crest-stage gages could be discontinued. An abundance of data at many crest-stage stations and a lack of data for urban area and flat-slope...

1985, Open-File Report 84-703
The U.S. Geological Survey, in cooperation with the cities of Littleton and Englewood, Colorado, studied the effects of the discharge of treated effluent from the Bi-City Waste Water Treatment Plant on low-flow conditions of the South Platte River. An 18-mile reach of the South Platte River, beginning below Chatfield Reservoir,...
An investigation of ground-water recharge by injection in the Palo Alto Baylands, California: Hydraulic and chemical interactions — Final report

1985, Water-Resources Investigations Report 84-4152
The U.S. Geological Survey, in cooperation with the Santa Clara Valley Water District, has completed a study of ground-water recharge by injection in the Palo Alto baylands along San Francisco Bay, California. Selected wells within the Water District 's injection-extraction network were monitored to determine hydraulic and chemical interactions affecting...
Low-flow frequency analyses for streams in west-central Florida
K.M. Hammett
1985, Water-Resources Investigations Report 84-4299
The log-Pearson type III distribution was used for defining low-flow frequency at 116 continuous-record streamflow stations in west-central Florida. Frequency distributions were calculated for 1, 3, 7, 14, 30, 60, 90, 120, and 183 consecutive-day periods for recurrence intervals of 2, 5, 10, and 20 years. Discharge measurements at more...
